Do-it-yourself alarm with a siren

Connecting an alarm system with a siren in the country with your own hands

If you plan to connect the house to the security system yourself, you will have to work a little, especially when deciding to make the alarm wired.

Wired system with howler

The task of installing a wired alarm with a siren involves performing certain actions:

Calculate how many wires are required, which is determined by the number of sensors to be installed and their distance from each other.
Howler and a signal lamp are hung from the outer wall of the property. It is advisable to attach these devices in the area under the roof. The siren can also be mounted in the house - right opposite the entrance. Thanks to this arrangement of the howler, the criminal is very scared, because the effect of surprise will work.

The sensor is mounted where it can better fulfill its purpose. Usually, its name hints at the place of this device, because sensors are responsive to movement, breaking glass or opening a door.
The central blocks are fixed near the door leading to the house. Devices that receive a signal from the sensor are selected after taking into account the power of the siren and the number of devices that monitor the penetration of unauthorized people into the house.

The wires must be inserted into special terminals on the sensors and the control panel. After connecting the wiring, the main cable is laid at least at a distance of 20 cm from other power lines

It is important to connect in accordance with the polarity. In this case, you should focus on the scheme.
Test the operation of the security system and adjust if necessary.

Connecting a GSM system with a siren

To create a wireless home security system, you need to purchase a PIR motion sensor, a 12V siren, a battery holder, a 6V relay, insulating tubes and wires.

The scheme will help to avoid mistakes when installing the alarm

Installation of a GSM system with a siren should be phased:

1. The motion sensor is reworked, transferring it from 220 V to 12 V. The fact is that the system only works with a supply voltage of 8 to 30 V. A 12 V sensor implies the installation of a relay with a voltage of 12 V.
2. The fixation device is opened to remove the spherical part by bending one of the supports. Then the board is removed from the sensor.
3. The points on the left of the devices supply power. To "+" connect the positive pole, and to "-" - the negative source of electric current. The relay winding is connected to the points on the right. After that, the black box (standard relay) is dismantled.
4. The relay is led through the wires to the base of the housing (due to the lack of space inside the spherical part). Power is supplied to the sensor using a switch. This is necessary so that the operation of the device directs current to the relay coil.
5. The siren and batteries are connected through the terminals. By the way, thanks to the relay, several howlers can be connected to the device.

Types of sirens for signaling

Sirens are divided according to the following differences:

• principle of sound generation;
• supply voltage;
• degree of sound pressure;
• type of connection and power supply.

Some of the varieties will be discussed below.

According to the principle of work

At the heart of the operation of sirens, two principles for the formation of a sound effect are used:

1. Piezoelectric. Car sirens use an inverse piezoelectric effect, based on the vibration of a piezoceramic plate under the influence of alternating currents. The frequency of the sound is determined by the frequency of the applied voltage, which ranges from 12 to 20 volts. A control microcontroller can be introduced into the siren design, which will allow generating a two- or three-tone sound. Car sirens are characterized by the ability to supply various sound signals and melodies that differ in frequency or discreteness. At industrial enterprises, 220 V voltage can be used for sirens of warning systems with a piezoelectric effect. Sound pressure is measured in decibels, for sirens in cars, a range from 75 to 115 dB is used.
2. Electromagnetic. The devices are a core of magnetized material, on which a coil of copper wire is wound. The core has a cavity inside, with a thin-walled metal partition installed in it - a membrane. When voltage is applied to the coil with a variable frequency (corresponding to the desired sound), the membrane begins to vibrate and form a single-tone sound with increased volume. To amplify the sound in the sirens, an additional generator is used, which amplifies the sound with a frequency in the range of 800-2000 Hz. The disadvantage of the design is the energy consumption and the need to use a voltage of 220 V. To date, electromagnetic type sirens are occasionally used in security systems of premises.

Type of connection and power supply

Sirens can be divided according to the method of communication with the control unit into wired and wireless.The latter receive a signal to operate via a radio channel of various frequencies.

Wired and wireless devices can have two power options:

• from the main source of energy - a car battery or a regular network in the premises;
• self-powered from its own source (accumulator or batteries).

Making a talking siren is shown in a video from the Tver Garage channel.

Wiring diagram of a piezo mini siren as sounding a warning security zone

For many alarms, along with disarming, the sensors are turned off and this is ideal for this scheme, but there are alarms in which, even after disarming, the sensor remains in working condition and continues to respond to the impact, in which case the connection needs to be changed, otherwise the mini the siren will continue to beep.

Even the most primitive alarm has an exit to block normally closed contacts. After arming, negative voltage appears on this wire, and after disarming, it disappears. This is the output we use, we connect the negative power supply of the sensor to it, but through the diode with the cathode in the direction of the alarm.

For everything to work correctly, you need to take two diodes, connect them with cathodes together and connect to our blocking wire. We connect the negative power supply of the sensor to the anode of one diode, and the blocking relay is connected to the anode of the second diode.

System details

Alert

The most commonly used are inexpensive and easy-to-install howler monkeys.

These are self-contained sound signaling devices. Anyone can install them without prior preparation.If you want to install a wired model, seek professional help.

In this article, we will also talk about the price of a gsm burglar alarm for a summer residence and the installation method.

The most important thing is to notify the neighbors after installing the howler

Show them all the possibilities of signaling so that in the future there will be no curiosities and misunderstandings. This is done for a reason - the sound of a signal can scare sleeping neighbors if a burglary attempt occurs at night. And the cottage or village where the house is located is included in the lists that private security is involved in, then they should also be warned about the alarm. Ideally, the system should be connected to the duty station, but this is not always possible to arrange.

It is worth turning on the siren at a time when you are not at the dacha, during working / night time, in winter, as well as when leaving (on vacation or in the city).

Working principle and description

It should be noted right away that you must have electricity on the site, otherwise, without it, the idea of ​​\u200b\u200binstalling a security alarm in the country will be a failure. Of course, you can always purchase a wireless alarm, but then you will constantly check the charge. For this reason, in order to be completely sure that even in your absence there will be safety, you should give preference to devices in a case that will not be afraid of moisture, so that the sensors can be used outdoors.

A standard alarm and howler kit contains a control panel with a power supply, motion sensors, a light indicator, a siren (howler), battery, cable and wires for connection, electronic keys and readers.

The principle of operation is that motion sensors are triggered, which react to movement, presence, opening doors or a broken window. They can be installed both in the house and on the outer wall. Once triggered, the howler beeps, which can last from three to ten minutes. The duration can be programmed during installation. After the set time has elapsed, the sound goes to 0. Even when triggered, the red light will flash, and during normal operation, the indicator just lights up.

• In order to connect a burglar alarm with a siren to the cottage, certain electronic keys should be used. With their help, the object can be removed from the alarm.
• If the electricity is suddenly turned off, the provided battery will be able to maintain the equipment in a state of operation for about a day.
• In order not to spend a lot on alarms, but at the same time to achieve an intimidating effect, you can use one or more dummies of a burglar alarm to give in the form of red lamps. They will act as movement indicators.
• The devices have a huge advantage in the sense that they can work perfectly even at a temperature of -30 degrees. With these characteristics, the howler can be installed in a non-heated room.
• Sensors are placed in the most “seductive” rooms for thieves, they must be located in the corridor and at the entrance. One sensor is enough for each room.
• You can buy a wired or wireless burglar alarm for your summer house. When choosing the first one, you will need the help of a professional during installation, since only those people who have been installing for more than a year know all the nuances. They will do all the house wiring correctly.
• Wired models have many more useful functions than analogues. But when buying wireless analogs, you won’t need to spend a tidy sum on wiring, and this will not affect the interior in any way.
• You can adjust the volume of the sound.

Connecting a security siren (howler)

batteries and radio signal receiver

The device of the security siren allows the installation of an LED light emitter in its body. Such light and sound signaling devices are widely used in security and fire alarm systems. They are compact, can be installed both indoors and outdoors and are notable for their low price. Recently, inexpensive motion sensors have appeared on the market, which are used to automatically turn on light sources.

Based on such sensors, inexpensive but effective security systems are produced. A security siren with a motion sensor is an effective means of protection for an apartment or a country house.

The composition includes the following elements:

• Ceiling Motion Sensor with 360 Viewing Angle
• internal siren
• Outdoor siren howler
• Power Supply
• Keychain remote control

Motion sensor detects an object up to 5 meters away

The internal siren produces a sharp sound of 100 dB, and the external device attracts the attention of neighbors or passers-by with a sound of 120 dB. The system is easy to install and very reliable.

A person inside the premises can sound an alarm by pressing a button on the key fob.

Security alarm based on motion sensor

The simplest security alarm system for home can be made by hand on the basis of a conventional household motion sensor for lighting, which are installed in entrances to save electricity. But instead of a lighting lamp, you can install a siren.

What will be needed for this?

Motion sensor - you can buy at any hardware store, such as OBI or Leroy Merlin

It is necessary to pay attention to the voltage of the sensor - we need it to work from a 220V network, the viewing angle - depends on the external design of the sensor (wall or ceiling) and the lens used (can be 180 degrees wide or corridor type). The average cost is from 400 to 800 rubles;
Siren powered by 220V

For example, PKI-3 "Ivolga-220", the average price is 250 rubles. Can be bought at radio stores;
A simple switch to turn off the alarm. Anyone will do, from 100 rubles. and higher.

The connection diagram is shown below:

motion sensor needed choose one that has at least two types of adjustments - time setting (TIME) and sensor sensitivity (SENS). With the help of the first one, it will be possible to set the time for the triggering of our alarm, i.e. siren sound time. This value is usually set for five minutes. The second adjustment changes the sensitivity of the sensor, for example, if it does not respond to you or to reduce the so-called "false alarms".

The switch will be needed in order to turn off the device when you are in its field of view and turn it on when you leave this room. It is advisable to install the switch discreetly, so that after activating the security alarm, you would not fall into its radius of action. In addition to the siren, you can also connect a regular light bulb for a double effect on the intruder.

The main disadvantages of such an implementation will be that after switching on, some models of motion sensors require from 1 to 10 seconds to “stabilize” and switch to standby mode. If you come across such a sensor, you need to add a time relay to the general circuit that will keep the siren turned off for the time it is turned on.

There are still miniature motion sensors on sale that operate on 12V, for example, model DD-03. You can also create a simple alarm on them, but you need to connect it to a 12 volt power source or a battery. Thanks to this, the system will be non-volatile and work even if there are power outages.

Wired or wireless

Communication between the sensors and the control unit can be provided both with the help of electrical wires and wirelessly (these technologies are so common today that you will not surprise anyone with them). Both methods have both advantages and disadvantages. The advantages of wireless communication include the absence of the need to lay a cable to each sensor. In the rest - continuous shortcomings. Any wireless sensor must be supplied with a battery. A dead battery can cause a false alarm of the system, and this is unpleasant. In addition, if the alarm works in winter, the battery life at low temperatures will be several times less. Thus, it is better if the “howler” siren in the country house is equipped with wired sensors.

Why is the howler alarm not working?

The howler siren can sometimes fail for several reasons:

1. The power was cut off during the installation of the wired system.
2. The whole system was connected incorrectly.
3. The batteries in the wireless device are dead.
4. An alarm was installed outside.
5. Manufacturing defect.
6. The attackers found a way to turn off the siren.
7. Water, dust, dirt got into the device and closed the contacts.

When choosing any type of howler siren alarm, you must carefully read the instructions in order to properly install and configure the system. Otherwise, your home will not be reliably protected, and unforeseen situations may occur, for example, frequent false alarms. Thanks to the sound warning system, you can be sure that strangers will not enter the territory of your country house or cottage.

Alteration and configuration of devices

Changing the nature of the sound of a standard car siren at the request of users in some cases requires a complete reconstruction or replacement of its main parts. To do this, you need only basic knowledge of circuitry, as well as skills in creating printed circuit boards.

It is possible to assemble a circuit of a two- or multi-tone car siren operating on a voltage of 12 or 15 volts in accordance with the following plan:

1. On paper or using a computer program, create a sketch of the printed circuit board.
2. Using a carbon copy or using a printer, transfer the drawing to glossy paper.
3. Cut out the template.
4. Process the blank from one-sided textolite with fine-grained sandpaper.
5. After degreasing the surface of the future board with an iron or a home-made device, stick a template on it.
6. Remove it by soaking it in warm water.
7. Etch the textolite plate in a solution consisting of 1 part of ferric chloride and 3 parts of distilled water.
8. With a thin drill, drill holes for the legs of the board elements.
9. Solder the radio components according to the diagram.
10. Install the generator inside the siren housing.
11. Carry out the installation of the sound annunciator at the place of its installation on the car.

Multi-tone siren

A multi-tone siren - from the variants of a sound annunciator with a changing tone, is assembled on the basis of a 561LN2 microcircuit, while:

1. The operating frequency of the generator G2, which is responsible for the tone of the siren, determines the state of the transistor VT1.
2. The parameters of its operation are controlled by setting the resistance of the variable resistor R1.
3. The G1 sound generator is responsible for the frequency of the produced signal. Its changes are achieved by adjusting the resistance R2.

To obtain a fixed sound tone, potentiometers R1 - R2 can be replaced with constant resistances with a nominal value of 33 kOhm.

Schematic diagram of a multi-tone siren

Dual Tone

A two-tone siren assembled according to this scheme is connected to the security alarm input and is not inferior to industrial samples in terms of the volume of the emitted signal. At the same time, it consumes significantly less energy and has its own, easily recognizable sound.

The pulses generated at the output of the multivibrator D1.3, D1.4 fall on the output stage, assembled on the basis of the transistor VT1. Influencing them with a signal with a frequency of 2 Hz, generated by the multivibrator D1.1, D1.2, two-tone sounding of the siren is achieved.

Scheme of a two-tone siren

Siren 12 Volt

Using only two transistors and a dynamic head with a resistance of an induction coil of 16 ohms (2 by 8 ohms), a simple siren circuit is assembled with a supply voltage of up to 12 V.

Siren circuit powered by 12V

Siren up to 15 volts

To work in conjunction with a car alarm, a siren assembled using the UMS-8-08 generator is suitable. The increased power of the device requires its connection through a special relay RES-10 (indicated as P1 in the diagram).

Siren with supply voltage up to 15 Volts

8 melodies are stored in the memory of the microcircuit, for the selection of which buttons are provided:

• S1 (start);
• S2 (stop);
• S3 (selection).

An audible signal at the output of the device is generated when the relay contacts are closed.

The microcircuit is powered through resistor R3 and diode VD1. Here the voltage drops to 3.3 volts. The signal from the collector of the transistor VT1 through the inverter D2.1 enters the input of the chip D2.3. It is also directly fed to the D2.2 chip.Due to the phase mismatch of the signals coming from D.2.2 and D.2.3 to the VT2/3/4/5 bridge, the current in the VA1 speaker circuit flows either in one direction or in the opposite direction. It is amplified by the coincidence of the positive and negative half-cycles of both signals.

The circuit is powered from a network with a voltage of up to 15V.

Siren based on a chip from a cell phone

A failed siren can be modified in accordance with the KA2410 chip from a cell phone call.

The signal is amplified by a transistor and sent to the speaker. A protective diode VD1 is installed at the input, which protects the circuit from incorrect connection (supply to positive negative voltage input).

A device based on a microchip from a mobile phone

We connect the alarm and siren

Any sirens for car alarms, if we talk about autonomous equipment, are equipped with all the necessary electrical contacts that allow you to make the correct connection. Another thing is that there may not be free control outputs in the connector of the signaling itself, or none of them can be programmed correctly. Perhaps then it will be possible to use a 2-amp contact intended for an on-line siren.

signaling connector, model unknown

A 2 amp cable can act as a positive control output (but this is not always the case).

Negative polarity control

An "external" siren for alarms can be controlled by a low-current output of negative polarity. This option is used in most cases. The Negative Trigger wire is connected to the control output, and the second "trigger" is left "in the air", that is, isolated.Nevertheless, it is recommended to connect the second control cord to ground.

Wiring diagram, ground control

Power is supplied to the autonomous module through a fuse. You can connect to the signaling power cord, and then do not install an additional pre-flask.

It is important to get high-quality contact with the ground, especially when it comes to controlling a negative impulse (the case under consideration). Whoever decides to ignore this advice will receive an unreliable operation in the situations provided for this.

So, after completing the installation and programming, carry out the verification.

Positive polarity control

Inside the siren loop for car alarms, which is designed for autonomous operation, you can always find a cord in white insulation. Some signalers are still supplied with positive polarity outputs, and accessory manufacturers are aware of this. The white cord must be connected to the output of the main unit. As soon as voltage appears on it, an alarm will sound.

Wiring diagram, positive control

The wire labeled as Negative Trigger always receives 12 volts, and the control voltage will go to the "positive trigger". However, Negative Trigger can be left "free", but then false positives are not excluded.

Instead of a signal output with positive polarity, a power output can sometimes also be used.

This property may have a contact provided for connecting a non-autonomous siren. Two cases are possible: this contact receives a constant voltage or an alternating voltage (rectangular pulses). In the first case, a suitable circuit is shown in this chapter.In other cases, it will be difficult to make a correct connection - additional modules will be required. The first option is typical for some imported signaling models. And Starline uses only the second one.

Tips for everyone

It is clear that the installation of any equipment is carried out by throwing off the "negative" terminal from the battery.

Negative battery terminal in car

But if the wiring on which the actions are performed is already connected to the pre-flask, then the recommendation can be neglected. True, most likely, then you will simply burn the pre-flask. Further, after connecting the siren, it will be possible to supply power and carry out a test. And then, in order to perform any actions, the autonomous module will have to be temporarily deactivated. The included key is used for this.

The module has a built-in mechanical lock

By turning the key in the lock, we give the command "to be silent." Then, it will be possible to remove the terminals from the battery, without fear of deafening from the alarm signal. The main thing is not to forget to return everything as it was. That is, the key will need to be turned in the opposite direction, but after connecting the battery. By the way, the mechanical lock itself can be tried to crack. You need to choose equipment based on this.

Ways to get intruders into the garage

A thief is able to get into the garage using the following methods.

1. A cut of the hinges or the padlock itself. The popularity of this method is due to the fact that it is the least noisy and as simple as possible. The padlock can not only be cut off, but also use large wire cutters, a sledgehammer or a classic crowbar.
2. Undermining is extremely rare, but still used, so attackers need to block the passage by concreting the floor and fixing the walls so that they cannot be lifted with a jack.
3. Creating a hole is allowed if the garage is metal. In this case, the principle of opening a tin can applies, and among the tools used are a classic grinder, hydraulic shears or an autogen. Sometimes a metal structure can simply be bent.
4. The use of master keys or paper clips to open the lock, the selection of keys. To be on the safe side, it is best to refrain from installing a rack and pinion lock, as it is too simple. There should be two locks.
5. Penetration through the roof is possible if it is jacked up or broken through, especially if there is a corresponding ledge above the walls. Car theft in this case is doubtful, but you can lose valuable property.
6. Broken brickwork. The speed of hacking in this case will depend on the quality of the bricks. In some cases, a small scrap will suffice. Often this method is used to penetrate into a neighboring garage, if nothing worthwhile could be stolen in the first one.

You may also be interested in the material that is devoted to installing such a device as a lock on a car from theft.

Be sure to read our expert's article on anti-theft mechanical devices for cars.

In fact, there are even more possible ways of hacking, so setting an alarm is a mandatory measure. Comprehensive protection, involving the installation of floor, wall, roof sensors, as well as vibration sensors, is an ideal option.It will not be superfluous to install warning sensors for opening gates or doors, movement inside the garage.

Despite the abundance of ready-made models on the modern security systems market, a garage alarm can be made independently. To do this, you need to know what requirements the finished device must meet.

Do-it-yourself laser alarm in a country house

Security systems with laser radiation are also popular. Such an alarm is triggered after an object enters the beam coverage area.

circuit diagram

A scheme for such an alarm can be drawn up with the inclusion of a laser emitter and a NE555 timer that controls the functioning of all elements of the system. As a laser receiver, a photoresistor is usually used, in which a small resistance is created during irradiation, and in its absence, changes occur in a large direction, which leads to the inclusion of an audible signal.

Due to the complexity of the circuit, installation of the system may seem difficult.

Installation of an alarm system with a laser pointer

In order for such an alarm to work, you will need to install:

• a laser pointer that generates a beam;
• photocell, i.e. a device with varying resistance;
• a relay that connects the elements of the system with a siren;
• fasteners for mounting;
• body parts;
• switching conductors;
• tools and materials for soldering wires and parts.

Installation of a laser security system is carried out as follows:

1. The wires coming from the sound siren and photocell, and the emitter power line are connected to the relay contacts.

2. The laser emitting special light and the receiver are mounted parallel to each other so that the beam goes to the center of the photocell.In this case, the sensor is placed in a black tube in order to close it from the light sources of the room.

3. The button responsible for turning the system on and off and the wires are positioned so that they are not visible, otherwise intruders will be able to extinguish the alarm.

Advantages and disadvantages of the laser system

The advantages of laser alarms include:

• high mobility, because the elements of the system can be easily transferred to another place;
• secrecy from intruders;
• the ability to connect both to the siren and to the remote control of the security company;
• use to create a system of improvised means.

Among the disadvantages of laser signaling are:

• high cost of parts;
• difficulties in installation and configuration.

Video: how to make the simplest do-it-yourself laser alarm

There is no full confidence that a home-made GSM alarm system and a laser security system can guarantee complete security. Still, such devices have a minimum of functions, and in terms of quality they are far behind their professional counterparts.

Alarm for giving. General information

Organization of security measures

The suburban area is a place of temporary residence. But even in such a place, a person tries to equip himself with coziness and comfort with convenient things. In the absence of the owners, it is difficult to keep track of things.

It is not cost-effective to hire security for each site. In such a situation, there is only one way out, to install an alarm for the cottage.

When organizing security measures to protect property, it is necessary to follow an unspoken rule; the offender must assume that the security at the facility is at a high level.

Since the territory of the location of the sites is usually located far from the places of deployment of law enforcement agencies, it becomes problematic to effectively organize the protection of things, the capture and detention of intruders in the event of an emergency situation.

Therefore, when choosing an alarm system, it is necessary to solve these issues as much as possible, but at the same time, the costs for it should not many times exceed the cost of the protected property.

Steps of protection

The alarm must have several levels of protection.

By their actions to attract the attention of guards and possible neighbors. This is produced by hidden sound and light blocks.
The complex requires a video camera with a good resolution

The image is important to immediately receive at the security point and the owner.
Opening sensors are installed on window frames, glass, entrance doors.

Motion sensors will help determine the presence of an uninvited guest, if he bypasses other controllers.

The best sensor option

• contact sensors. Respond to opening.
• Infrared radiation detectors. Activate a danger signal in the presence of unauthorized presence. The downside is the reaction to animals.
• Video cameras. They help to obtain accurate information about the state of affairs at the facility. In case of a false alarm, you can remotely restore the protection.
• Devices with infrared radiation. Complement the performance of video cameras.
• Impact sensors. Place them on glass. React to impact or glass breaking.

Cascade protection will provide more reliable protection of the cottage than the use of one type of controller.All components work together, and even false alarms are important for understanding the integrity of the entire system during the arming of the object.

For greater confidence, dummies of video cameras are additionally installed around the perimeter of the building. This will scare away the little hooligans.

Wired

In the case of the location of the guard on the territory of subordinate areas, a system with wired data transmission is selected.

Important! The positive side of this equipment is considered to be low cost, timely response and delivery of information to a central point.

The downside of the equipment is a power outage, a break in the wire.

Autonomous system

Installed indoors. Simple operating principle. The system includes motion sensors, opening sensors for doors and windows. There is no direct connection with the owner.

Does not connect to the remote control of private security. Works from the accumulator. In case of unauthorized entry, it produces a high-pitched sound signal.

The principle of surprise and fear is used. High probability of attracting the attention of the watchman or neighbors.

Alarm system with GSM module

The most perfect for the protection of a remotely located cottage. The cascade of sensors is connected to a single unit equipped with two SIM cards from different cellular providers. Any signal is sent simultaneously to the security console and to the owner of the facility.

For reliability, information is received immediately on a personal computer in the form of a video file for recording, on a cell phone or smartphone SMS, MMS, photo and video file.

The system can be powered simultaneously from the mains and from the battery. This will allow you to keep working in any conditions.The ability to obtain timely information will allow you to quickly respond to the situation that has arisen.

Important! This alarm system is good for everyone, but it is expensive. Most of all, it is suitable for private expensive houses.
