The 407 non-addressable reflective beam line-type smoke detector is suitable for connection to 2-wire non-addressable fire detection control and indicating equipment, or to addressable fire detection control and indicating equipment that can accept non-addressable type detectors.

The transceiver component has four selectable detection ranges, providing smoke detection over distances from 8 m to 100 m. Three sensitivity settings can be used to compensate for differences in installed environments.

Automatic compensation adjusts for lens contamination, alignment drift, ambient light conditions and transmitted beam ageing. Operational parameters are set using a separate hand-held device manager.

The 407 non-addressable reflective beam line-type smoke detectors provide fire detection and alarm system designers with a Standards-compliant, economical smoke detector for high spaces and areas with complex ceilings where point-type smoke detectors may not be suitable due to environmental conditions.
