Honeywell (MI-LPB2-S2I) Intelligent Optical Smoke Beam Detector

Honeywell (MI-LPB2-S2I) Intelligent Optical Smoke Beam Detector

The MI-LPB2I is an intelligent reflector type linear optical beam smoke detector designed to operate as a component of an intelligent fire alarm system. It operates primarily on the principle of light obscuration utilising infra-red light. Optical beam smoke detectors are particularly appropriate for protecting buildings with large open spaces such as warehouses, atriums etc.

The MI-LPB2I detector is combined transmitter/receiver units, which can be directly connected to an intelligent loop without the need of a separate local power supply. The Infra-Red transmitter generates a beam of light receiver where an analysis of the received signal is made. The change in
the strength of the received signal is used to determine the alarm condition.

The MI-LPB2-S2I includes both the standard protocol and the Advanced Protocol and contains a short-circuit isolator.
