Underwriters Laboratories Inc. has evaluated and listed their first motorised beam detector as compliant with the American National Standards for safety.  The Fireray 5000 from Fire Fighting Enterprises now boasts certification from UL in addition to LPCB, CPD & EN54:12, breaking new ground in the development of this smoke detection technology.

The F5000 incorporates several technological advancements that set it apart from previous detectors.  A newly-developed motorised beam head works in conjunction with the sensor to automatically optimise the signal strength throughout the life of the unit.  This works to keep the beam aligned with the reflective prism even in the event of gradual building shift, and can also factor in environmental factors such as dust buildup.  These features strengthen false alarm immunity over time, and help to reduce the need for maintenance operations. 

These new additions for the F5000 improve its functionality, whilst it retains the benefits intrinsic to the tried, tested and trusted beam technology that has preceded it: large area coverage per unit (~19800 sq ft as opposed to ~900 sq ft for a point type detector), reduced cabling and installation costs, and minimal aesthetic intrusion. 

The Fireray’s low-level system controller is connected to the detector head by a two-wire cable, and can be used to fully control and adjust the beam – making installation significantly easier.  The detector head houses both the transmitter and receiver, with the beam being bounced off a prismatic reflector on the opposite wall.  Beam-type detectors are particularly suited to protecting wide indoor spaces such as warehouses, open-plan offices, corridors and meeting-halls.  By covering large areas with few units, costs and disruptions caused by installation and maintenance can be greatly reduced, and the fire security system can be much less obtrusive – which can be of particular benefit in historic or stylish settings.
