Aspirating Smoke Detection Systems

An ASD system continuously draws air through a network of pipes and actively samples it for smoke particles. It uses a highly sensitive sensor, often laser-based, to detect smoke at the earliest stage of a fir, far earlier than conventional detectors.

ASD is ideal for high-risk or mission-critical environments, such as:

• Server rooms and data centres

• Cold storage and refrigerated areas

• Warehouses with high ceilings

• Cleanrooms and healthcare settings

• Heritage buildings and museums

• Correctional facilities and transportation hubs

Yes. ASD systems are often used in dusty or industrial environments because the detection unit is remotely located, away from the source of contamination. Many models include air filtration systems to ensure accurate performance.

Plastic (often red) sampling pipes are installed throughout the protected area with strategically placed holes. The ASD system continuously draws air through these holes into the detection chamber for analysis.

No. While extremely sensitive, modern ASD systems use intelligent algorithms and programmable alarm thresholds, which help minimise false alarms while ensuring early detection.
