Description

STANDARD EN54-7 Ed2000 / Full CE marking according to CPD
Number of certification: 0333 CPD 075 013
The Optical smoke detector analyzes an atmosphere by reflection of a light on the particles of smoke
according to TYNDALL effect. It detects especially the cold and visible smoke particles (0,3µm to 2µm)
produced in the early stages of a fire. The threshold of response of alarm is regulated to obtain the value
m=0,2db/m±0,03 according to standard EN54-7.
OC05 includes a developed technology (microprocessors, smd components) which means precision and
high reliability. A specific head detection fixed by a single ceiling base.
12V version of OC05 detectors is also available for security type systems
