FireRay 3000 Active Infra-Red Optical Beam Smoke Detector

The FireRay® 3000 End to End Infrared Optical Beam Smoke Detector (OBSD) has been designed using the latest optical technology, incorporating modern industrial, electronic and software techniques. This detector offers cost effective protection of large, open area spaces with high ceilings. It is also very suited to applications where access to ceiling mounted smoke detectors presents practical difficulties.

The FireRay® 3000 is ideal for applications where line of sight for the IR (infra-red) detection path is narrow and where the building structure uses reflective surfaces. It has also been designed to be aesthetically pleasing and thus can equally suit modern architectural buildings as well as heritage sites, particularly where ornate ceilings exist.

The FireRay® 3000 has been designed so that it can be installed by one operator, with its laser assisted alignment method combined with easy to use alignment LED’s offering a visual feedback. Integrated laser alignment aid can be activated at the controller or at the Receiver head.

An additional detector head set (one transmitter & one receiver) can be added to the controller, separate relay contacts are provided for each of the 2 beam sets.


  • Separate Transmitter and Receiver Heads
  • Range 5 to 120 metres, configurable per set of Detectors
  • Integral Laser Alignment in Receiver
  • 2-wire Interface between Controller and Receiver
  • Single and Twin Detector options
  • Separate Fire and Fault Relays per Detector
  • Low Level Controller with LCD display
  • Programmable Sensitivity and Fire Threshold
  • Automatic Gain Control (AGC) for drift compensation
  • First Fix concept for Transmitter, Receiver and Controller
  • Multiple cable gland knockouts for ease of wiring
  • Optional Transmitter powering from Controller
