High-precision aspirating smoke detectors

Issue 5 2020 Fire & Safety

The SecuriSmoke ASD range by Securiton offers three VdS approved models and makes the lightning-fast detection of fires both scalable and cost-effective for any area – be it a single facility or an area measuring up to 5760 m2.

The ASD535 is the flagship model and available as either a single- or two-sensor device. It can monitor an area of up to 5760 m2 at temperatures ranging between -30°C and +60°C while retaining full functionality at all times. In deep-freeze applications, the unit is installed directly in the area and the sampling holes are heated automatically when needed, to prevent freezing.

The ASD533 is a scaled-down version of the ASD535 and suited for areas up to 1920 m2 with temperatures ranging between -20°C to +60°C. Dusty, steamy or dirty conditions make no difference to the ASD535/533. Their extremely low noise levels (34 dBA) make them compliant with ISO standard 11690-1 for the design of low-noise workplaces containing machinery.

The ASD532 is suited for small and medium-sized areas of up to 1280 m2 with temperatures ranging between -20°C to +60°C. It has the same technical specifications as the ASD535, but with just one sampling pipe and a more compact fan.

The compact ASD531 is ideal for areas up to 720 m2 with temperatures ranging between -10°C to +55°C, making it an effective, cost-effective option for applications such as elevator shafts, electrical distribution cabinets, false ceilings, clean rooms, ventilation ducts, and IT racks.


The FidesNet network solution is typically used wherever remote visualisation and operation are required, or in difficult-to-access or restricted-access areas. Multiple SecuriSmoke ASDs can be connected in a network offering an at-a-glance overview and straightforward operation on the 7-inch colour touch panel.

The extensive range of SecuriSmoke accessories includes various dust filters, water retaining boxes and other tools.
