Ravel RE-317D-SHL: Analogue Addressable Multi-Sensor (Smoke & Heat) Detector

In addressable fire alarm and life safety installations, multi-sensor detection provides early and reliable fire detection while significantly reducing unwanted false alarms. The Ravel RE-317D-SHL is a low-profile, analogue addressable multi-sensor detector designed specifically to work with AVANI series addressable fire alarm control panels.

Dual-Technology Detection & Drift Compensation

The RE-317D-SHL combines optical photoelectric smoke sensing with thermistor-based thermal detection. The thermal element triggers an alarm at a fixed temperature threshold of 59°C (138°F) or when a rapid temperature rise exceeds 11.1°C/min (20°F/min). The optical smoke chamber features a wide-spectrum sensing design with an integrated insect filter and programmable sensitivity levels via the Fire Alarm Control Panel (FACP). It incorporates an advanced drift compensation feature that automatically adjusts the detector's baseline reference according to ambient environmental changes.

Addressing, Communication & Sleek Design

Operating across an 17–28 VDC input voltage range, system addressing for up to 254 devices is easily set using an onboard 8-way DIP switch. Dual LEDs provide 360° visual indication (blinking red during normal standby and solid red during alarm activation). Built in a sleek, low-profile housing designed to fit a standard 100mm base, it supports air velocities up to 4,000 fpm and features an open-collector remote indicator output (2 mA max).
