Design and function

ASD 533 Aspirating Smoke Detector

The ASD 533 (Aspirating Smoke Detector) is the latest generation of a highly sensitive, active smoke detection system from Securiton, now available in the UK from Patol Ltd. 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 533 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 smoke concentration levels is detected very early. Three pre-alarm and two main alarms can be programmed and forwarded to a fire alarm control panel via volt free relay contacts.

The ASD 533 is suitable 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, highrack storage facilities, etc.). Or because lightning-fast detection is required, e.g. in data centres.

A high-power LED, combined with a Large Volume Smoke Chamber (LVSC), results in unparalleled adjustable sensitivity with low aerodynamic resistance and the utmost resistance to soiling and contamination. These features ensure long system service life and durability. Commissioning and maintenance of the ASD 533 is done via the ASD Config PC Tool, and are calculated using the ASD PipeFlow software. This makes it possible to configure more cost-efficient asymmetrical pipe layouts. The optional MCM35 memory card module allows extensive long-term smoke level recordings (e.g. smoke and airflow values) to be stored directly on the SD memory card and analysed on your PC.
