Fireray 100R / 50R Reflective Infrared Optical Beam Smoke Detector (50m- 100m)

Description

The FIRERAY 50R/100R sequence of reflective infrared Beam Detection optical beam smoke detectors are comprised of a one device incorporating an infrared Transmitter and Receiver. The signal is mirrored by a prism and analysed for smoke presence.

The technique is made to be mounted so that the beam will project in between .three and .6 metres underneath and parallel to the ceiling. Lateral detection may be up to seven.5 metres either side of the beam.

The 50R/100R has three selectable ‘Alarm Thresholds’ settings of 25%, 35% and 50% which can be selected to suit the environment. If the
received infra-red 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 infra-red 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 infra-red 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.

Key Features:

• Single Compact Housing
• Area coverage 50 metre or 100 metre model available
• 12-24 Vdc Operation

Applications:

The Fireray 100R/50R series of reflective infrared optical beam smoke detectors provide economical and effective protection of large, open plan spaces with high ceilings, particularly if access to ‘point type’ smoke detectors presents practical difficulties.
