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.
OA05 includes a developed technology (microprocessors, smd components) which means precision and high reliability. A specific head detection fixed by a single ceiling base.
OA05 is dedicated to interactive fire detection panels.
The smoke detector OA05 is designed to be installed under flat ceiling with heights ranging between 2, 5 m and 12 m and this, in healthy and more or less ventilated buildings.
The maximum supervised surface is 80m² by detector; however it is preferable to refer to the local rules of installation recommended in particular when the characteristics of the installation differ from those stated above. Eight levels of sensitivity are available while programming the fire detection panel (from 0,1dB/m to 0,35 dB/m).
Photoelectric scattering (Tyndall effect)
1 remote alarm indicator output
Cable section max 2,5mm²
8 levels sensitivity setting (0,1 dB/m to 0,35 dB/m)
Base isolator (option)
Base relay (option)
Constant sensitivity thanks to auto correction
