How Do Burglar Alarm Door Sensors Work

The two pieces are installed next to each other one on the door and one on the wall right next to the door.

How do burglar alarm door sensors work. The good old light sensor. When they separate such as when the door or window is opened the sensors send a signal to the alarm panel. The sensor in turn signals the control box which can be programmed to emit a bell noise or sound an alarm. The magnet needs to be in very close proximity to the sensor when the door is closed or else the device will not work properly.

When the system is armed and a door or window is opened the two magnetic sensors are separated from each other thereby tripping the alarm. But do you know how home burglar alarm sensors actually work and how secured it can be. These sorts of alarms are divided into two categories. Any combination of these three motion sensors may be found in a building s security system and they all play a vital role in keeping your home or business safe.

In a closed circuit system the electric circuit is closed when the door is shut. Some security companies such as simplisafe allow customers to decide whether a triggered sensor means a full on alarm response an alarm response with a detailed event report sent to your email or phone a smart alert or a private text or email without a public alarm event a secret alert. The panel will then assess the situation and notify you of unusual activity inside your home. The best door alarms can easily be controlled with the sensor s remote or your smartphone.

Once the door alarm is attached to your door frame you should be able to control the sensor with ease. The magnet is placed on or inside the door or window itself. The sensor is typically installed on or inside the stationary frame of the door. Remote access allows you to conveniently turn the sensor on off or test the battery.

A pitch sensor is a bit different. We call active sensors the devices emitting energy captured by a receptor. If a protected door or window with a sensor is open you will not be able to arm the system until the door or window is closed or the zone is bypassed. The standard sensor works the same as on any other door.

This means that as long as the door is closed electricity can flow from one end of the circuit to the other. The sensors utilize magnetic fields in order to track movement between the door or window and the frame. The magnet is then mounted on or inside the moving portion of the door usually within a half inch of the sensor. Simplisafe calls their door sensors entry.

When the door or window is opened the magnet will separate from the sensor causing it to activate. When the garage door is raised it breaks the circuit and sets off the alarm. In a burglar alarm the switch detects the act of intrusion opening a door or window for example.
