Ajax GlassProtect Glass Break Sensor — White

Ajax GlassProtect is a wireless glass break detector for rooms with large windows, shopfronts and sliding doors, where an intruder is more likely to come through the glass than the door. It listens for the sound signature of breaking glass up to 9 m away across a 180° arc. The white glossy enclosure suits it to living and retail spaces.

The DualTone digital algorithm only raises an alarm when it hears the low-frequency thump and the high-frequency shatter within 1.5 seconds, which keeps everyday noise out of the log. Three sensitivity levels let you tune it to the room, and NC terminals let a third-party wired detector share the same radio link. It mounts on a SmartBracket panel with no wiring and no need to open the case, and the pre-installed CR123A battery runs for up to 7 years.
