Wireless Portable Glass Break Alarm System

The tattletale Glass Break Sensor is designed to detect the breaking of tempered, coated, plate, and multi-pane glass. 2-stage detection requires there to be a thump of an object hitting glass and the breaking of the glass to take place in order to trip the sensor. When installing make sure the test button is pointing towards the floor for proper detection.”,”highlights”:[“Integrates seamlessly to tattletale for quick and easy set-up”,”Detection range of 15 ft. over 360° cone for reliability”,”Powered by 2 lithium batteries to ensure long-lasting use”
