BV-502GB DSC

Product Overview

The BV-502GB is a hardwired, ceiling-mounted dual-technology security sensor engineered to combine passive infrared (PIR) motion tracking and acoustic glass break analysis within a single overhead enclosure. Providing 360-degree omnidirectional coverage, it incorporates a downward-facing Fresnel lens and an optimized quad-element PIR sensor to capture volumetric movement, alongside an advanced microphone that actively monitors for the frequency of shattering glass. This specific model features a built-in supervised housing tamper switch and stands out by utilizing a standard double Form C output structure, giving security systems fully isolated normally open or normally closed dry contacts for both individual motion and glass break reporting circuits.

Key Features

• Dual-Technology Protection: Packages a 360-degree quad-element PIR motion tracking system and an acoustic microphone together for complete room perimeter and volumetric safety.
• Dual Form C Terminals: Configured with two separate Form C dry relay contacts, providing fully flexible normally open or normally closed (NO/NC) connections for both the motion circuit and the glass break circuit.
• Supervised Cover Tamper: Equipped with an integrated, hardware-monitored tamper safety switch that generates a panel trouble alert if the outer housing cover is removed.
• Microprocessor Glass Filtering: Uses specialized dynamic signal evaluation to accurately capture the structural sound profiles of plate, tempered, laminated, and wired glass breakage while excluding background bell and ringing sounds.
• Multi-Level Signal Processing: Employs advanced internal algorithms to read infrared thermal profiles, distinguishing true human intrusion from background noise and ambient air shifts.
• Central Height-Proportional Coverage: Protects a circular floor region spanning a 24-foot diameter when suspended at an 8-foot ceiling level, adjusting up to a 36-foot detection profile at an 12-foot height.
