Technical Details

Fireray 50R Optical Beam Detector For Fire Alarm Systems Reflective Beam 5 - 50 Metres

The FIRERAY 50R reflective infrared optical beam smoke detector comprises of a single unit incorporating an infrared Transmitter and Receiver. The signal is reflected by a prism and analysed for smoke presence. The system is designed to be mounted so that the beam will project between 0.3 and 0.6 metres below and parallel to the ceiling. Lateral detection may be up to 7.5 metres either side of the beam.

The FIRERAY 50R optical beam smoke detector can be connected to a zone of a conventional fire alarm control panel, or interfaced to an analogue addressable system via an addressable interface input module or a zone monitor module.

The FIRERAY 50R has three selectable 'Alarm Thresholds' settings of 25%, 35% and 50% which can be selected to suit the environment. If the received infrared signal reduces to below the selected threshold for approximately 10 seconds, the fire relay is activated.There are two modes of operation for the fire relay. 'Auto Reset Mode' will reset the fire relay approximately 5 seconds after the received infrared signal has recovered to a level above the alarm threshold. 'Latching Mode' holds the fire relay active indefinitely after an alarm condition has occurred.

If the infrared beam is obscured rapidly to a level of 90% or greater for 10 seconds the fault relay is activated. This condition can be achieved in a number of ways, for example, an object being placed in the beam path, transmitter failure, loss of the prism, or sudden misalignment of the detector.The fault relay will reset within 5 seconds of the condition being rectified.

The FIRERAY 50R optical beam smoke detectors monitor long term degradation of beam signal strength caused by the build up of dirt on it's optical surfaces; this operates by comparing the received infrared signal against a reference voltage every 15 minutes.

For UL models only, an optional 'Low Level Test Unit is available to test the correct function of the beam detectors at ground level. Operation of a key switch will produce a periodic flash of the green LED on the Low Level Test Unit confirming the beam detector on test is 'live'; after a set period the red LED on the Low Level Test Unit and the red LED on the beam detector illuminate simultaneously.

Applications

The Fireray 50R reflective infrared optical beam smoke detector provides economical and effective protection of large, open plan spaces with high ceilings, particularly if access to 'point type' smoke detectors presents practical difficulties.
