DSC LC-203 PIR Motion Detector with Pet Immunity, Dual Technology with Antimasking

Detect real threats while reducing false alarms — the DSC LC-203 PIR Motion Detector delivers dependable detection and streamlined installation for professional security and surveillance deployments. As a Dual Technology PIR motion sensor with pet immunity and built-in antimasKing, the LC-203 blends a fully digital PIR with LODIFF optics and POLY IR materials to deliver stable performance and fewer nuisance alerts from pets or environmental interference. Compatible with any hardwired control panel and powered by 13.8V DC, the detector supports a maximum detection range of 49.2' for flexible coverage across corridors, offices, and residential zones. Integrators benefit from internal EOL resistors that cut wiring time and simplify integration with PowerSeries Neo and PRO panels, while robust white-light and RFI protection ensure consistent monitoring in industrial and high-traffic settings. Ideal for installers and security managers looking to enhance alarm accuracy, the DSC LC-203 is purpose-built for reliable intrusion detection and ongoing surveillance operations.
