The AirSense Stratos HSSD2 High Sensitivity Smoke Detector (9-30706) is a large-area aspirating smoke detector (ASD) with a sheet steel enclosure, providing very high sensitivity smoke detection for the earliest warning of an incipient fire with a minimum of nuisance alarms. Laser-based forward light scatter gives reliable early warning over areas of up to 2000m² through a combined sampling pipe length of up to 200m.
Volt-free fire and fault relay outputs allow remote monitoring by a local fire detection panel or BMS, and RS485 communications are built in for networking. A Command Module is available for central monitoring and display. It is suited to computer rooms, data storage, equipment racks, plant and motor rooms, air-conditioning units and duct protection, heritage properties, prison cells and other critical areas.
Key features
- Laser-based forward light scatter for very high sensitivity
- ClassiFire® Perceptive Artificial Intelligence automatically adjusts the operating parameters to the protected environment and to contamination of the dust separation system, so the detector runs at high sensitivity in a computer room or reduced sensitivity in a smoky area without complex set-up
- Patented Dual Technology LDD 3D3 Laser Dust Discrimination avoids unwanted alarms from dust
- Up to 2000m² coverage from 4 pipe inlets
- RS485 communications built in; SenseNET compatible, up to 127 detectors per loop
- Options: Addressable Protocol Interface Cards (APIC™), remote display units and MatrixScan virtual addressable location software
- CPR, LPCB, VdS, NF, CSIRO, UL and FM approved
