Overview
Protect occupants and property with dependable, installer-friendly detection crafted for commercial security and fire monitoring. The System Sensor 4WTR-B is a 4-wire, photoelectric combination detector with an isolated thermal sensor and Form C relay that delivers early smoke recognition and added heat detection to reduce nuisance alarms and improve overall system reliability. Its photoelectric sensing chamber targets smoldering fires while the thermal element provides backup in high-draft or high-heat areas.
Designed for efficiency, the i3 series plug-in base and Stop-Drop 'N Lock mounting simplify installation and support neat pre-wiring; inline terminals and ample base space speed up commissioning. The 85 dB built-in sounder provides strong local alerting, and maintenance features such as remote maintenance signaling, drift compensation, and simplified sensitivity measurement minimize service visits and lifecycle costs. Operating on 35 V DC and backed by a 3-year limited warranty, the 4WTR-B integrates smoothly into security, surveillance and building automation systems for continuous monitoring.
Ideal for offices, retail, healthcare and institutional environments, the System Sensor 4WTR-B improves detection accuracy and lowers total cost of ownership—add it to your life-safety system or contact us for configuration assistance.
