Detect earlier.
Respond sooner.
A high-performance fan continuously draws air through the sampling pipe network. After filtration, the air is analysed in the detection chamber so staged alarms can be raised at the earliest signs of smoke.
PRODUCT RANGE
Four models.
One standard of reliability.
The SecuriSmoke ASD range scales from compact equipment rooms to large data centres, high-bay storage and complex industrial environments.

Compact single-pipe system
ASD 531
Designed for individual server racks, equipment rooms, clean rooms and compact protection zones.

High-sensitivity single-pipe system
ASD 532
Engineered for data rooms, clean environments, laboratories and high-reliability projects.

High-performance single-channel system
ASD 535-3
For large data centres, high-bay storage, deep-freeze warehouses and demanding industrial spaces.

Flagship two-channel system
ASD 535-4
Two independent detection channels for extensive spaces and two-zone protection strategies.
INDUSTRIES AND APPLICATIONS
Purpose-built protection
for demanding environments.
Sampling points can be placed where air actually flows, while detection units remain in easily accessible locations for maintenance.

Data centres
Continuously samples air in high-airflow spaces to identify incipient smoke before conventional point detection.
Logistics and warehouses
A maintainable sampling network addresses high racks, smoke stratification and hard-to-reach detection points.
Clean rooms and controlled environments
Stable air sampling supports high-value processes in clean rooms and other high-air-change environments.
Rail and rapid transit hubs
Sampling pipes extend detection into stations, equipment rooms and complex spaces where point detectors are difficult to place.SELECTED PROJECT REFERENCES
