System Sensor SS-PTIR Addressable Photoelectric / Thermal / IR Smoke Detector with Base

Protect your facility and reduce costly downtime with the System Sensor SS-PTIR addressable combination detector. This multi-criteria detector (photoelectric, thermal and infrared) improves alarm accuracy by correlating data from three sensing elements—rejecting nuisance sources like transient smoke or steam while still responding quickly to real fire conditions. The thermal element supports a 135°F fixed temperature threshold plus rate-of-rise detection, and the unit is UL 268 7th Edition and UL 521 listed for code-compliant performance. Addressable rotary switches make device identification fast and precise, while low standby current and support for SK, LiteSpeed and SS protocols simplify integration into existing fire alarm networks. Dual 360° LEDs and a modern profile help with quick visual inspection and professional aesthetics across commercial, healthcare and educational sites. Ideal for security and building monitoring programs where reliability and reduced false alarms are critical.
