AirSense Stratos HSSD2 High Sensitivity Smoke Detector with Command Module (9-30620)

The AirSense Stratos HSSD2 High Sensitivity Smoke Detector with Command Module (9-30620) is a large-area aspirating smoke detector (ASD) with a polycarbonate plastic 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. An integrated Command Module provides central monitoring and display of up to 126 detectors. 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
• Integrated Command Module for central monitoring and display of up to 126 detectors
• Options: Addressable Protocol Interface Cards (APIC™), remote display units and MatrixScan virtual addressable location software
• CPR and VdS approved
