Napco GEM-GB Wireless Glass Break Detector

The GEM-GB is an advanced wireless acoustic glass-break detector for use with all Gemini-Series control panels and receivers. Each transmitter has a unique RF ID code (printed on the sensor module and on the rear case) that distinguishes itself to the receiver. Refer to control-panel instructions for entering this code and its checksum digit into the panel. Be sure to enter all numbers and/or letters, including leading zeros, if any.

The detector is powered by two type DL123A 3-volt lithium batteries, which are factory installed. To energize the unit, simply install the supplied Power-Up Jumper across pins JP1 near the positive terminals of the batteries.
