SecuriSmoke ASD 533 supplied by Securiton AG
The SecuriSmoke ASD 533 (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 smaller monitoring areas and sampling distances where a reduced sampling performance is sufficient.
Design and function
The SecuriSmoke ASD 533 consists of a fan, a highly sensitive smoke sensor, an airflow measurement system, and evaluation electronics. The fan sucks in air samples through the sampling holes from the room or facility being monitored and then feeds the samples 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 soiling of the sampling holes.
The display and control panel of the evaluating processor unit indicates alarm, fault and status reports. Any increase in smoke concentration levels is detected very early. Three presignals and two main alarms can be programmed and forwarded to a fi re alarm control panel either via potential free relays or directly to the SecuriLine addressable loop.
Applications
The SecuriSmoke ASD 533 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 (prisons, false ceilings, clean rooms, laboratories, high-rack storage facilities, etc.). Or because lightning-fast detection is required, e.g. in data centres.
