ALPHA 3000 (SHIELD)
ALPHA
3000 END TO END BEAM DETECTOR
The
SHIELD Alpha 3000 End to End infrared Optical Beam Smoke Detector (OBSD) has
been designed using the latest optical technology, incorporating modern
industrial, electronic and software techniques. This detector offers cost
effective protection of large, open area spaces with high ceilings. It is also
very suited to applications where access to ceiling mounted smoke detectors
presents practical difficulties.
The SHIELD Alpha 3000 is ideal for applications where line of sight for the IR (infrared) detection path is narrow and where the building structure uses reflective surfaces. It has also been designed to be aesthetically pleasing and thus can equally suit modern architectural buildings as well as historical sites, particularly where ornate ceilings exist.
