System Sensor SS-PHOTO-R SS-Series Photoelectric Smoke Detector for DNR(W) Duct Smoke Detectors, Remote Test Capable

Ensure dependable duct smoke protection with the System Sensor SS-PHOTO-R photoelectric smoke detector, engineered for consistent performance in commercial HVAC and duct monitoring applications. This SS-Series detector uses a photoelectric sensor to detect smoldering and slow-burning fires early, minimizing false alarms and protecting sensitive equipment and occupants. Designed for integrators and facility managers, it supports wired analog communications, rotary address switches for fast setup, and a wide 15–32 V DC input range with low standby current to reduce installation complexity and power draw. The SS-PHOTO-R is UL 268 listed and compatible with DNR(W) duct housings and major addressable systems, helping streamline inventory across security, fire alarm, and surveillance projects. Remote test capability speeds routine maintenance and compliance testing, lowering service time and operational disruption. With visible dual LEDs for 360° indication and a modern profile for clean installations, this detector delivers reliable monitoring in ductwork and mechanical rooms.
