The Flagship Model For Large-Scale Applications

The ASD 535 aspirating smoke detector monitors large facilities with areas of up to 5,600 square metres. It is available with one or two sensors. Up to 400 metres of sampling pipe with a maximum of 120 sampling points in total can be connected to each sensor. With over 400 Pa of aspirating underpressure, the ASD 535 has one of the most powerful fans on the market. It is perfect for use in harsh environments, such as deep-freeze areas, explosion hazard areas or rooms with high levels of contamination. Thanks to the new “Config over Line” function, the detectors can be configured and serviced from the fire alarm control panel.

An Even Tougher ASD 535 For Extreme Applications

Tried and proven over many years, the components of the ASD 535 were designed with a higher protection class of IP 66 for use in extreme conditions, thus enabling the devices to also be deployed in wet and dusty environments. All components have a special protective coating to comprehensively safeguard the electronics. Use in corrosive environments such as agricultural and industrial applications ensures that entire systems are fully monitored.

The SecuriSmoke ASD 533 aspirating smoke detector is the latest generation of this 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. 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 ultra-rapid detection is required, such as in data centres.

The Compact Solution For Small to Medium-Sized Applications

The ASD 532 has a sampling tube length of up to 120 metres and works reliably at temperatures of between -20 °C and +60 °C. Thanks to its compact design, it is perfect for use in elevator shafts, prison cells, clean rooms, laboratories, IT racks, telecommunications facilities and many other applications. It has the same technical specifications as the more powerful ASD 535 model, but with just one sampling pipe and a more compact fan.

Simple and Convenient for Smaller Premises

The ASD 531 offers quick commissioning and the highly professional monitoring of smaller areas and premises, and all without the need for training. The detector is configured directly on the device without the need for a PC and operation is uncomplicated. As with the two larger models, it is also equipped with the tried-and-tested HD detector with LVSC (large-volume smoke chamber). This results in outstanding sensitivity combined with an impressively long service life.
