Patol ASD531 Single Sensor Standard Display with SSD531 Detector The ASD 531 (Aspirating Smoke Detector) is the new generation of a highly sensitive, active smoke detection system. It is based on the successful ASD 535 and is particularly well suited for monitoring smaller areas and sampling distances where a reduced sampling pipe network is sufficient. The ASD 531 consists of a fan, a highly sensitive smoke sensor, an airflow measurement system, and evaluation electronics. The fan draws in air through sampling holes from the room or facility being monitored and then through a sampling pipe to the evaluating processor unit. Here the air samples are continually monitored for smoke particles by the smoke sensor. Airflow monitoring ensures that the sampling pipe is constantly checked for pipe breakage and any obstruction of the sampling holes. The display and control panel of the evaluating processor unit indicates alarm, fault and status reports. Any increase in the smoke concentration levels are detected very early. Three fixed pre-alarms and one main alarm which can be forwarded to a fire alarm control panel via volt free relays contacts. The ASD 531 is used whenever conventional point-type smoke detectors cannot be used. This may be due for example to ambient conditions (too hot, too cold, too dirty) or because operating conditions are such that access is highly restricted (Elevator Shafts, prisons, false ceilings, clean rooms, laboratories, etc).
