The S1000 is a cost effective and aesthetically pleasing non-addressable optical smoke detector. These detectors are designed for open area protection and provide the earliest warning of fire, whilst utilising advanced chamber design to ensure reliability and a high level of unwanted alarm rejection. A centrally positioned LED indicator provides 360° visibility of detector activation and an in-built magnet test feature allows easy activation to verify operation of the detectors. A selection of connection bases make the unit compatible with most conventional control equipment.
