Door and window sensors

« Back to Glossary Index

Door and window sensors are an essential component of any burglar alarm system, whether it is for commercial or residential use. These sensors are designed to detect any unauthorized entry into a building through doors or windows. They work by sending a signal to the alarm system when the door or window is opened, triggering an alarm and alerting the monitoring center or the property owner.

Door and window sensors come in different types, including magnetic sensors, which use a magnet and a sensor to detect when a door or window is opened, and acoustic sensors, which use sound waves to detect any movement or vibration. Some sensors are also equipped with motion detectors, which can detect movement within a certain range and trigger an alarm if someone enters the building.

In addition to detecting intruders, door and window sensors can also be used to monitor the comings and goings of employees or family members. They can be programmed to send alerts when a door or window is opened during certain times of the day or when a specific person enters or leaves the building.

1. How do door and window sensors work in burglar alarms?

Door and window sensors work by detecting when a door or window is opened or closed. They consist of two parts: a magnet and a sensor. The magnet is placed on the door or window frame, while the sensor is placed on the door or window itself. When the door or window is opened, the magnet moves away from the sensor, triggering the alarm.

2. How many door and window sensors do I need for my burglar alarm system?

The number of door and window sensors you need for your burglar alarm system depends on the size and layout of your home or business. As a general rule, you should have sensors on all exterior doors and windows, as well as any interior doors that lead to areas with valuables. You may also want to consider adding sensors to any windows that are easily accessible from the ground.

3. Can door and window sensors be installed on sliding doors and windows?

Yes, door and window sensors can be installed on sliding doors and windows. However, they may require a different type of sensor than traditional doors and windows. For example, sliding doors and windows may require a sensor that is designed to detect movement rather than a magnet and sensor combination. It is important to consult with a professional burglar alarm installer to determine the best type of sensor for your sliding doors and windows.
