GSM alarm system allows you to identify an alarming situation that arose when the sensors were triggered and transmit it in the form of a voice, text or other message to the owner and (or) law enforcement agencies. In order to make this system on your own, it is necessary to study the object and determine the signaling components.
Instructions
Step 1
Make a list of sensors that you need to monitor the object. For example, if you want to protect your home from strangers, it is recommended to install sound sensors, motion sensors, noise sensors, glass break sensors, impact sensors, magnetic contact sensors, smoke sensors.
Step 2
Install all detectors of your GSM alarm system in the required places of the room Magnetic contact sensors must be installed on the front door. They are triggered if someone enters the apartment unauthorizedly. The signal from them is transmitted to the control unit, which issues a sound signal or other set command. Motion sensors are installed in all the main rooms of an apartment or house.
Step 3
If you are afraid that the enemy will sneak into the house through broken glass, then you need to install an appropriate sensor, which looks like an almost invisible grid. In this case, the appearance of the window will suffer a little. If you do not want to save on safety and strive to preserve the beauty of the interior, then you can purchase special audio detectors that aim at the windows and fix their damage. If you are afraid of fires, it is recommended to install smoke detectors complete with an automatic fire extinguishing system.
Step 4
Choose a place to install the control unit. It must be equipped with a special remote GSM antenna. Mount the antenna in an area with stable GSM signal reception. To do this, point it towards the nearest base station. The unit itself should be in an easily accessible place in the apartment at a height that is inaccessible to children.
Step 5
Connect the sensors to the control unit, and then establish the connection of the latter with the sirens, which will receive a corresponding signal or message about an alarm situation.
