Morley IAS MI LPB2 Addressable Optical Smoke Beam Detector

Fire Projects recommend Morley-IAS MI-LPB2by Honeywell is an addressable 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 an Infra-Red beam. Fire Projects has done several installation of optical beam smoke detectors, which are particularly appropriate for protecting buildings with large open spaces such as warehouses, atriums etc.
The Morley-IAS MI-LPB2 detector is a combined transmitter/receiver unit that can be directly connected to an analogue loop circuit. The Infra-Red transmitter generates a beam of light towards a high efficiency reflector. The reflector returns the beam to the receiver where an analysis of the received signal is made. Fire Projects may change in the strength of the received signal is used to determine the alarm condition.
The sensitivity of the detector can be set by Fire Projects between 25% and 50% obscuration, providing application flexibility to suit the environment in which the detector will be installed. In addition to the four fixed value alarm thresholds, there are two variable thresholds that automatically compensate for changes in the environment which could otherwise result in unwanted alarms while remaining within a known sensitivity range. Beam detector installed by Fire Projects can incorporates automatic drift compensation, whereby the detector will adjust its detection thresholds in line with any long term signal reduction of the beam caused by contamination of the optical surface. The detector can be adjusted up to 10° vertically and horizontally for alignment. Where greater angular adjustment is required, the multi-mount accessory enables the detector to move through 28° vertically and 360° horizontally when ceiling mounted or up to 23° vertically and 90° horizontally when wall mounted.
