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.

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.

A DFU 911 dust filter unit can be installed in the sampling pipe tube network for use with an ASD aspirating smoke detector in applications subject to dust or dirt. This significantly extends the service life of the smoke sensors, air flow sensors and fans used in the ASD and results in enhanced resistance to false alarms. A filter monitoring function in the ASD can be activated to indicate the optimal time to replace the filter element after a defined, application-specific filter service life has elapsed.

The SIM 35 serial interface module is for networking multiple ASD or ADW special fire detectors via RS485 bus. Using the “ASD / ADW Config” configuration software, all ASD or ADW units present in the network can be visualised and operated from a PC. The SIM 35 provides galvanic separation between the RS485 interface and the special fire detectors.
