ASD 535

ASD 535

Design and function

The ASD 535 Aspirating Smoke Detector from Securiton, now available in the UK from Patol Ltd, consists of a choice of one or two independent sampling lines with sampling apertures, each with a highly sensitive smoke sensor. Air flow monitoring ensures that the sampling lines are constantly checked for pipe breakage, and the sampling holes monitored for pollution. A high-performance ventilator draws in the air from the room or facility being monitored, through the sampling line to the evaluating processor unit. There the air is continuously evaluated by the specially developed SSD 535 smoke sensors.

The display and control panel of the evaluating processor unit indicate the smoke concentration of the sampled air and other alarm, fault and status messages. Any increase in the smoke concentration is detected very early. Three pre-signals and two main alarms can be programmed and signalled via potential-free relays or directly to the SecuriLine ring circuit.

There are four expansion slots for accommodating modular relay, interface and memory card prints.

Key Features

Key Features

Highly sensitive smoke sensor

The SSD 535 smoke sensor was specially developed for the ASD 535 and is the result of extensive research. Use of a high-power LED, combined with a large volume smoke chamber (LVSC), results in unparalleled, adjustable sensitivity with the lowest aerodynamic resistance and supreme resistance to pollution and soiling. This ensures a long service life.

Easy to plan and commission

For straightforward, standard installations, the ASD 535 with EasyConfig offers fast, foolproof, computer-free commissioning. More complex installations are calculated using the ASD PipeFlow calculation software and configured with ASD Config, the commissioning and maintenance software. This allows for more cost effective asymmetrical pipe layouts. The optional MCM 35 memory module facilitates the comprehensive long-term logging of smoke levels directly to the SD memory card for analysis on a computer.
