RE – 317D SHL

The RE-317D-SHL is an addressable multi-sensor detector developed by Ravel, designed to enhance fire detection systems by integrating both smoke and heat sensing capabilities. This detector is engineered to provide rapid and reliable responses to fire incidents, ensuring optimal safety across various environments.

Key Features:

• Dual Detection Mechanism:
  Combines photoelectric smoke detection with fixed temperature and rate-of-rise heat detection. The heat sensor activates at 59°C (138°F) or when the temperature rise exceeds 11.1°C per minute (20°F/min).

• 360° Visibility:
  Equipped with dual LEDs, the detector offers clear visual indicators from any angle. The LEDs blink during normal operation and remain steady to signal a fire condition.

• Polarity Insensitivity:
  Designed to be polarity-free, simplifying the installation process by eliminating concerns about wiring orientation.

• Advanced Communication Protocol:
  Utilizes sophisticated detection and communication protocols to ensure accurate and timely information relay to the fire alarm control panel (FACP).

• Insect Filter:
  Features an insect-resistant design to prevent false alarms caused by small debris or insects entering the detection chamber.

• Programmable Sensitivity:
  Allows sensitivity adjustments via the FACP, enabling customization based on specific environmental conditions.

Technical Specifications:

• Operating Voltage: 17 to 28V DC
• Standby Current: 500 µA
• Alarm Current: 5 mA
• Remote Output: Up to 2 mA (open collector)
• Smoke Sensitivity: (2.12 ± 0.61) % obs/ft, with settings for high (1.1%), medium (1.4%), and low (2.3%) sensitivity
• Air Velocity Range: 0 to 4000 feet per minute
• Operating Temperature: -10°C to 37.8°C
• Humidity Range: 0 to 95% relative humidity, non-condensing
