Description

The Ravel RE-337H is a high-accuracy addressable heat detector engineered to integrate with the Avani series fire alarm control panels.1 It utilizes a sophisticated thermistor-based sensing circuit to monitor ambient temperature levels.2 The detector is typically configured to trigger an alarm when it reaches a fixed temperature threshold of 59?C (138?F) or detects a rapid rate-of-rise in temperature, depending on the panel configuration.

Features

  • Dual-Action Sensing: Combines Rate-of-Rise detection for fast-developing fires with Fixed Temperature sensing for slow-burning fires that reach a high thermal threshold.
  • False Alarm Immunity: Highly resistant to smoke, steam, and airborne dust, making it the preferred choice for areas where photoelectric detectors would cause nuisance alarms.
  • Full 360° LED Visibility: Equipped with two LEDs on opposite sides of the detector head; a blinking red light indicates normal polling, while a steady red light confirms an alarm state.
  • Analogue Data Transmission: Constantly reports temperature values to the main panel, allowing for intelligent fire-sensing algorithms and early “pre-alarm” warnings.
  • Maintenance-Friendly Design: Without an optical chamber to clog, the RE-337H requires less frequent cleaning than smoke detectors and offers a longer service life in harsh environments.
  • Manual DIP Switch Addressing: Features an 8-position DIP switch for straightforward manual addressing, ensuring the address remains locked even if the device is powered down.
  • Base Compatibility: Designed to lock securely into the RE-314B standard base or the RE-314BI isolator base for protection against loop short circuits.
