Aspirating Smoke Detectors

Aspirating Smoke Detectors are among the most reliable high sensitivity smoke detection (HSSD) devices for the early warning of fire.

About the product

The ASD range impresses with its proven monitoring technology and unrivalled performance.

Developed in Switzerland and manufactured in Germany, the aspirating smoke detectors are particularly reliable and robust. Thanks to their sophisticated detection technology, actively drawing air into the detector for very fast detection of smoke particles, they can detect incipient fires immediately. An active monitor alerts if operation is compromised, such as the smoke detector being masked.

Whether in IT racks, production halls or large deep-freeze areas, Patol has the perfect fire protection solution for all safety requirements. ASD detectors are available in three models, with the main difference between them being the maximum possible monitoring area. This means that protection without compromise is now even more cost-effective in small premises.
