The AirSense Stratos Micra 100 (9-30764) is a compact, high-sensitivity aspirating smoke detector (ASD) using laser-based forward light scatter for very early warning of fire. This version is supplied with the 9-30436 input/output expansion card already fitted.
ClassiFire artificial intelligence automatically sets the detector to the best sensitivity for the protected area, and the detector fits into a docking station so that pipes and cables can be installed first and the detector fitted at commissioning. Typical applications include data storage, computer rooms, equipment racks, plant and motor rooms, air-conditioning units, prison cells and heritage properties.
Key features
- High sensitivity from laser-based forward light scatter
- ClassiFire perceptive artificial intelligence adjusts operating parameters for day-to-day changes in the environment
