Description

The Securiton ASD 535 Aspirating Smoke Detector is highlighted as a highly reliable early warning fire detection system, offered in both single-sensor and two-sensor configurations. This detector boasts substantial coverage capabilities, with the two-sensor variant protecting areas up to 5,760 square metres. Each sensor can accommodate up to 400 metres of sampling pipe, incorporating a maximum of 120 sampling points, with independent analysis of airflow from each pipe to detect deviations, breakages, or blockages.

Engineered for robust performance, the ASD 535 is equipped with a powerful fan delivering over 400 pascals of aspirating underpressure. This feature makes it particularly well-suited for demanding environments such as deep-freeze areas, explosion hazard zones, or locations with high levels of contamination. It is also designed to be immune to common disturbances like dust, dirt, moisture, and steam, ensuring dependable detection and minimised false alarms.

The detector is housed in a modern IP54 enclosure and features a “Config over Line” function, enabling convenient configuration and servicing directly from a fire alarm control panel. It provides three EN54-20 compliant sensitivity classes – A, B, and C – offering adaptable options for diverse operational requirements, alongside both standard and advanced LED display options for clear status indication.

Furthermore, the Securiton ASD 535 supports dual pipe lengths of up to 400m each and allows for flexible orientation of pipe inlets. It holds a comprehensive set of international approvals, including VdS, FM, UL, UKCA, and CE, affirming its compliance with global safety and quality standards. Its technical specifications detail a broad supply voltage range and precise alarm sensitivity settings.
