Door sensors are a basic part of your home’s security system. This wireless home security system feature provides a barrier to the vulnerable entry points into your house. Door sensors use electrical circuits to work. However, this home security system feature will fail eventually unless properly maintained. Understanding how wireless home security system door sensors work will help you understand more about how to secure your house.

Door sensors use electrical circuits to work

Electricity needs a clear path through which to flow. This electrical path is usually referred to as a circuit. An electrical circuit begins at one point and ends at the same point, in a continuous path. If that path is closed, the electricity continues to flow. However, if there is a break in the path, the electricity cannot flow.

Door sensors use electrical circuits to work. The sensor has a source of electricity. In a wired home security system, that source is the home’s electrical feed. In a wireless home security system, that source is a battery installed in the sensor.

Home security system door sensors come in two parts. There is the piece secured to the door and the piece secured to the frame around the door. Each piece has a magnet. When the door is closed, the magnets are in contact. The electricity can flow through the magnets, completing the circuit. However, when the door is open, the magnets are apart, breaking the circuit.

When the electrical circuit is broken, this activates the home security system alarm. The sensor will send a signal back to the central control panel that the entry point has been opened.

Those that are authorized to enter the home have an access code that will disable the alarm. However, if no one enters a valid access code, the alarm is sent to the central monitoring service, who can contact emergency personnel as needed.

Eventually, door sensors will fail unless properly maintained

Door sensors, either wired or wireless, will fail eventually. Some mechanism inside the sensor will sustain damage or just wear out. If a door sensor in your home is malfunctioning, it is very important to replace it immediately. Until this feature is fixed, it is a point of vulnerability in your home security system.

If you have wireless door sensors, you need to make sure to test and change the batteries as recommended by the home security company. Having a dead battery means having a dead door sensor.
