DSC WLS922L-433 Wireless Glassbreak Detector

Protect your premises from window-entry intrusions with the DSC WLS922L-433 wireless glassbreak detector. Designed for commercial and residential security systems, this DSC glass break sensor uses a high-performance microphone and Dynamic Signal Processing to distinguish true glass break events from everyday noise — reducing nuisance alarms and improving monitoring reliability. The detector recognizes all common framed glass types (plate, float, tempered, wired and laminated) and offers an installer-selectable DIP switch with two sensitivity levels so integrators can tune detection for storefronts, offices or busy lobbies. Wireless, hybrid-ready installation and two included lithium batteries let technicians deploy the unit quickly and integrate it into alarm system architecture and repeater networks. A tamper-activated test mode (compatible with the AFT-100 glassbreak simulator) streamlines commissioning and routine checks. Ideal for security integrators, facility managers and surveillance installers who need dependable window protection, the WLS922L-433 enhances intrusion detection and overall monitoring effectiveness. Add it to your next security or alarm system upgrade to strengthen perimeter defense.
