Product Details


Stratos-HSSD has unmatched sensitivity potential, providing the earliest warning of incipient fire with minimum rate of nuisance alarms.

ClassiFire perceptive artificial intelligence ensures that the detector operates at optimum sensitivity for the protected environment, without the need for complex setup. This means the detector will configure itself to provide high sensitivity in a computer room or reduced sensitivity in a smoky area.

Volt-free fire and fault relay outputs are available for remote monitoring by local fire detection or BMS system. Each detector is provided with 3 pairs of remote control input terminals. The inputs may be configured for a number of functions.
