Napco PGB Glassbreak Transmitter

Protect windows, storefronts and glass-fronted exposures with the Napco PGB Glassbreak Transmitter, a compact wireless glassbreak sensor engineered for dependable intrusion detection. As part of the Napco Security Technologies Prima line, this transmitter uses a 433MHz omnidirectional acoustic sensor to listen for breaking glass and deliver long-range alerts—up to 656' open air—back to your security panel. The unit ships with a CR2477 3V lithium battery and offers tamper supervision plus 1-way encryption to help maintain signal integrity and reduce nuisance alarms during daily surveillance and monitoring.

Designed for installers and security managers, the PGB mounts quickly with included self-stick tape or optional screws, enabling fast rollout across commercial and residential sites. Its small footprint (2.53" x 1.49" x 0.53") fits discreetly near glazing while providing robust acoustic coverage. Ideal for integration with intrusion detection systems, alarms and central monitoring services, the Napco PGB streamlines protection of glass vulnerabilities.
