BEAM FIRE DETECTOR USE AND
UCL BUILDING LOCATIONS
USE OF BEAM DETECTORS
Beam Smoke Detection - Beam Detection is used where
situations that the installation, testing, and maintenance of point
type detectors is difficult. For example, in spaces with high
ceilings, once construction has been completed and the space is
occupied, it is often difficult to reach the ceiling without the use of
heavy, cumbersome lifts operations or where that there are large
open expanses etc.
UCL use the optical reflective beam smoke detector unit and
reflective mirror type as per the picture.
The Optical Reflective Beam Smoke Detectors
Beam Smoke Detector works on the principle of light obscuration. The photosensitive element of
the Optical Beam Smoke Detector sees light produced by the Transmitter (TR) in a normal
condition and uses a reflective mirror to return the light beam back to the transmitter. Any
obscuration of the beam detector including smoke, objects (poles, helium filled balloons poles
brushes or persons will imitate a fire signal and place the premises into full fire evacuation.
Transmitter
Mirror Reflector
Any object other than smoke will set the beam detector off passing through the
beam.
Procedure For Working by Beam Detectors
Design Consultants, Consultants, UCL Project Managers and Contractors please note that a ‘Permit
to Work’ on fire alarm systems is required to prevent the unwanted automatic calling of the fire brigade
when working at height or in the vicinity of beam detectors - your will require a Permit (requiring 72 Hours
Notice) to be issued and instruction to isolate the beam detectors during the day time only by an approved
Project Manager. Consultation with Fisk Fire Group & UCL Maintenance Engineers before commencing
general or construction work will be necessary
