FR50R - Reflective Optical Beam Smoke Detector 5 to 50m range FIRERAY

The FIRERAY 50R conventional infrared optical beam smoke detectors provide economical and effective protection of large, open plan spaces with high ceilings, particularly if access to 'point type' smoke detectors presents practical difficulties.
Optical beam smoke detectors are ideally suited for protecting warehouses, factories, atria, shopping malls, leisure centres, churches,museums, power stations and industrial plants.
The FIRERAY 50R optical beam smoke detectors can be connected to a zone of a conventional fire alarm control panel, or interfaced to an analogue addressable system via an addressable interface input module or a zone monitor module.
