DESCRIPTION 

Conventional photoelectric smoke detectors are state-of- the-art detectors suitable for connection to 2-wire or 4-wire non- addressable fire detection control and indicating equipment, or to addressable fire detection control and indicating equipment that can accept non-addressable type detectors1.

Advanced electronics in conjunction with a photoelectric smoke sensing chamber provide early detection of fire and high immunity against unwanted alarms.

Conventional detector range provides fire detection and alarm system designers with a Standards-compliant economical smoke detector for life safety and property protection applications.
