Glass break sensor

« Back to Glossary Index

A glass break sensor is a device used in the burglar alarm industry to detect the sound of breaking glass. It is a type of sensor that is designed to detect the unique sound frequency of breaking glass and trigger an alarm. This device is commonly used in commercial and residential settings to protect against break-ins through windows or glass doors. The glass break sensor is an important component of a comprehensive security system, as it provides an additional layer of protection against intruders.

When a glass break sensor is triggered, it sends a signal to the alarm system, which then activates an alarm. This alarm can be audible or silent, depending on the preferences of the homeowner or business owner. The glass break sensor is designed to be highly sensitive, so it can detect the sound of breaking glass from a distance. This means that it can be placed in a central location and still provide coverage for multiple windows or glass doors.

1. How does a glass break sensor work?

A glass break sensor works by detecting the sound frequency of breaking glass. When the sensor detects the specific frequency, it triggers the alarm system to alert the homeowner or monitoring service. Some sensors also use vibration detection to detect the impact of breaking glass.

2. Where should I install glass break sensors in my home?

Glass break sensors should be installed in areas where there are windows or glass doors that could be easily broken by an intruder. It is recommended to install sensors in every room with windows or glass doors, as well as in hallways and stairwells. The sensors should be placed within 25 feet of the glass and should be mounted on the ceiling or wall, facing the glass.

3. Can a glass break sensor be triggered by other sounds?

While glass break sensors are designed to detect the specific frequency of breaking glass, they can sometimes be triggered by other loud sounds, such as thunder or a slamming door. However, most sensors are designed to filter out these false alarms and only trigger the alarm system when the specific frequency of breaking glass is detected. It is important to test the sensor regularly to ensure it is working properly and not triggering false alarms.
