An aspirating smoke detector (ASD) continuously draws air through a network of sampling pipes to a central detector, where a highly sensitive sensor looks for the first traces of smoke. Because it senses a fire in its incipient stage, long before visible smoke or heat, it gives people time to act before damage or downtime occurs.
Aspirating smoke detection is the right choice for data centers, cleanrooms, telecom rooms, cold stores, warehouses with high ceilings, heritage buildings and other places where point detectors are hard to reach, hard to see, or not sensitive enough. EN 54-20 defines three classes: Class A for very high sensitivity, Class B for enhanced sensitivity and Class C for normal sensitivity. In North American and many Middle East projects the detectors follow UL 268.
Kidde Global Solutions offers ModuLaser for demanding and larger installations, the compact MiniLaser for small and medium spaces, and AirSense aspirating detection, available through Kidde Commercial, Edwards and AirSense.

They describe sensitivity. Class A is very high sensitivity, Class B is enhanced sensitivity and Class C is normal sensitivity. The class you need depends on the risk and the room. Learn more: EN 54-20 Class A, B and C explained
Yes, periodic checks of the air filter and the sampling pipes. The detector monitors airflow and reports faults, which makes service simple.
A fan draws air from the protected space through a network of sampling pipes into a detector. A highly sensitive sensor analyses the air for the first traces of smoke and raises staged alarms, and the system monitors airflow so a blocked or broken pipe is reported as a fault.
Testing follows the manufacturer's instructions and local rules: introduce test smoke at the sampling hole furthest from the detector, check the alarm and the transport time, and confirm airflow and fault monitoring. Testing is part of the regular service of the system.
The cost depends on the number of detectors, the length and layout of the pipe network, the classes and approvals needed, and the installation. Tell us about the building and our team will give you a quotation.
