Ravel RE 326-2SL Photo Electric Smoke & Fixed Temperature Heat Detector

The Ravel RE 326-2SL is a conventional multi-criteria fire detector manufactured by Ravel Electronics for commercial, industrial, and residential fire safety installations. Combining an optical photoelectric light-scattering smoke chamber with an electronic thermistor heat sensor inside a low-profile white enclosure, the detector monitors smoke particle obscuration and fixed thermal thresholds (57°C) simultaneously. Driven by an onboard micro-controller, the unit evaluates signals from both sensors to deliver fast response times to both smoldering smoke and rapid heat increases while providing high immunity to false alarms. Operating across a 9V to 33V DC 2-wire conventional zone loop, it features dual clear-lens 360-degree status LEDs, direct support for remote LED indicator outputs, low quiescent power consumption, and compliance with UL 268 and IS 2175 standards.
