Learn Mode Glass Guard Sensor
The Learn Mode (LM) Glass Guard Sensor is designed to be mounted directly on glass in doors, windows, gun cabinets, etc. The LM Glass Guard utilizes a LM Door Window Sensor with no reed switches or magnets. A piezo crystal and sensor circuit have been attached to the terminal block and sensor base. When the glass that the sensor is mounted on breaks, the break will activate the LM transmitter.
