Speak to an expert
The Napco GEM-GB is an advanced wireless acoustic glassbreak detector for use with all Gemini-series control panels and receivers. Using an omnidirectional acoustic sensor, it detects the distinctive high-frequency sound signature of breaking glass — covering all windows in a room from a single ceiling or wall-mounted detector — and transmits a wireless alarm signal to the Gemini panel, triggering the alarm without any wiring to individual windows.
