Fireray R Optical Beam Smoke Detector

Fireray R Optical Beam Smoke Detector

The new Fireray® R is the latest Optical Beam Smoke Detector from FFE. Building on our long heritage of innovative products, the Fireray® R is easy to install and has a number of patented features which reduce false alarms. 

The Fireray® R automatically compensates for environmental effects such as dust, sunlight and building movement to keep false alarms and faults to a minimum.

The built-in laser and auto-alignment function makes the Fireray® R easy to install, saving on installation and commissioning costs. The system is fully customisable with both the alarm thresholds (sensitivity) and delay to alarm/fault being controlled from the ground level system controller. An easy-to-use interface unit with a backlit LCD display and fully icon-based.

How does it work? 

An Optical Beam Smoke Detector uses an infra-red Transmitter and Receiver to monitor a signal in an open area. When smoke passes through the invisible infrared Beam, the solid particles and liquid droplets in the smoke reflect and scatter the photons of light. 

The result is that the intensity of the light is reduced. This reduction is known as obscuration and can be detected to signal a fire.

The important thing to note is that this effect occurs equally at all points along the beams path. This ensures that the detector behaves effectively as though it was made up of an infinite number of Point Detectors arranged along a line. 

This makes optical beam smoke detectors ideal for protecting long distances (up to 120m for a single beam), providing that the beam is completely unobstructed and correctly aligned with the detector.
