High sensitivity air sampling smoke detection system with HSD detectors in a 2m high
raised floor:
– 6 or 12 BDH 2450.1 detection devices with interface card BDC2400 (pre-alarm 15%,
Alarm 30%)
– 6 AD2 active detectors
Air sampling tubes:
– 2 air sampling tubes mounted parallel in 2 metre high raised floor; first tube 1.25m above
the floor, second tube 1.85m above the floor, both in front of the aspiration filters of the air
circulation fans.
Air sampling holes:
– Holes every 60cm (see planning guidelines)
Response sensitivity:
– The system reacts to a test fire with 5 metal film resistors 10Ω 0.6W connected in parallel
at 9V max. 5A.
