SDAU Aspiration Smoke Detector

SDAU Aspiration Smoke Detector

SDAU is a high sensitivity aspiration smoke detector, certified in respect of European product standard EN54 20 Class A, B and C. It’s endowed with CE mark agreement according to ZA directive enclosure “Construction Products Directive” 89/106/CEE. SDAU is compliant to European directive 2002/95/CE, concerning the use of dangerous substances inside electrical products, in particular about the use of lead.

SDAU consists of one or two independent aspiration pipe networks with sampling apertures, each with a highly sensitive smoke sensor. Air flow monitoring (independent control for each network) ensures that the sampling lines are constantly checked for pipe breakage and the sampling holes monitored for pollution. A high performance aspirator sucks the air from the monitored area through the sampling holes to the evaluating processor unit. There the air is continuously evaluated by the smoke sensors. SDAU is able to indicate the smoke concentration of the sampled air and other alarm, fault and status via LCD and specific LED. Any increase in the smoke concentration is detected very early. Three pre signals and one main alarm can be programmed for each network and signalled via voltage-free relay. There are four expansion slots for accommodating modular relay interfaces and memory card for events logging.
