Description

The Ravel RE-337SH is an intelligent addressable multi-sensor detector designed to provide early warning for both smoldering and fast-flaming fires. By combining a photoelectric chamber with a high-accuracy thermistor, the detector analyzes both smoke density and temperature changes, significantly reducing the occurrence of false alarms caused by steam or dust. It operates on a digital protocol compatible with the Avani series panels, featuring digital addressing via an 8-way DIP switch and a sophisticated drift compensation algorithm that maintains sensitivity even as the sensor accumulates dust over time.

Features

  • Dual-Technology Sensing: Combines light scattering (photoelectric) and thermal sensing to detect everything from dense smoke to high-heat flaming fires, ensuring maximum safety.
  • Intelligent Discrimination: The internal microprocessor analyzes signals from both sensors to differentiate between real fire signatures and non-fire phenomena (like steam or dust), minimizing nuisance alarms.
  • 360° Visibility: Features two tri-color LEDs placed on opposite sides of the detector, ensuring that the device’s status (Normal, Fault, or Alarm) can be seen from any angle.
  • Analogue Value Reporting: Constantly transmits precise environmental data to the control panel, allowing for pre-alarm warnings and maintenance alerts if the sensor becomes contaminated.
  • Rate-of-Rise & Fixed Heat: The thermal element triggers an alarm if the temperature increases rapidly or if it reaches a fixed threshold of 59°C providing protection even in smokeless fire scenarios.
  • Durable Construction: Built with a specialized insect screen and a dust-resistant chamber to ensure long-term stability and reduce service calls.
  • Easy Installation: Compatible with the RE-314B standard base or RE-314BI isolator base, featuring a simple twist-lock mechanism for rapid deployment.
