Description
Standard EN54-7 Ed2000
Security addressing
CE certified according to CPD
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).

TS1000
Tripod turnstiles are compact and cost-effective entrance solutions. Designing for smooth and silent operation, reducing power consumption, wear and tear. It is suitable for areas with a high traffic.
The TS1000 series, our stainless steel compact version,offer high operating reliability in a small casework, ideal for sites where space is an issue. By receiving a signal from the access control system, or pushing button, it allows the entry of one person in a time. Entering into different directions are electronically controlled. Default mode is to lock the mechanism until a valid authorization signal is received. IIf you want to set one side free, you can adjust the mechanism. In case of emergency, the horizontal arm will drop to allow free passage.
