The GB-501 PG2 is a wireless two-way glass-break detector that detects the breaking of framed glass mounted in an outside wall.
The GB-501 PG2 applies PowerG 2-way transceiver technology, and is made up of two modules:
Sentrol ShatterPro™ acoustic sensor with Pattern Recognition Technology™ (protected under U.S. Patent 5,192,931)
Visonic MC-302 PG2 transmitter
The acoustic sensor shares its housing with a miniature transmitter using PowerG 2-way communications protocol.
Upon alarm (glass break detection), a digital message is transmitted, composed of the PowerG ID followed by various status and message-type markers. Alarm and other data are thus forwarded to the wireless alarm control panel.
The GB-501 PG2 is protected by a front tamper switch and back tamper switch that is activated when the cover is removed or when the base is forcibly detached from the wall. In a tamper situation, a message is transmitted with the “tamper alert” marker ON.
A periodic supervision message is transmitted automatically. The wireless control panel is thus informed, at regular intervals, of the sensor’s active participation in the system.
A red LED mounted on the transmitter PCB (visible only when the cover is off) lights whenever alarm or tamper events are reported. The LED does not light while a supervision message is being transmitted.
