Overview
Aspirating smoke detectors from Securiton are among the most reliable early warning systems for fires.
Available as a single-sensor and two-sensor device, the Securiton ASD 535 Aspirating Smoke Detector can cover large areas of up to 5,760 square metres. Each sensor can accommodate up to 400 metres of sampling pipe with an overall maximum of 120 sampling points.
The airflow from each sampling pipe is analysed independently and reliably detects any deviation in the airflow, as well as detects any breakages or blockages in the sampling pipes.
Securiton ASD 535 Aspirating Smoke Detector has one of the most powerful fans on the market with over 400 pascals of aspirating underpressure. It is ideal for use in harsh environments such as deep-freeze areas, explosion hazard areas or rooms with high levels of contamination.
Securiton aspirating smoke detectors are housed in a modern IP54 enclosure and can be configured and serviced from the fire alarm control panel thanks to the “Config over Line” function.
Area Coverage
The single sensor version of the Securiton ASD 535 Aspirating Smoke Detector can cover an area of up to 2880m2 while the two-sensor version can cover areas up to 5760m2.
