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.
