SYSTEMOVERVIEW SYSTEMFUNCTIONALITY •Beam detectors are typically used to replace individual point detectors in large open areas such as warehouses, advantagesinclude:-Single device to install instead of numerous point detectors-Provides single point of maintenance.-Wall mounted for ease of maintenance, especially in warehouses with racking •Beam detector is supplied with reflector (single reflector for 50 Metre version and 4 individual reflectors mounted together for 100 Metre version)•Beam detector is powered directly from the zone or loop,no additional power supply is required•Simple two wire connection •Fire and fault conditions are signalled to panel using standard zone or loop wiring no additional interconnection required•Only one beam detector may be connected per zone•Reflective beam detector is specifically designed to operate with Menvier and JSB panels, use with other types of panels is not recommended•Sensitivity setting can be altered by DIP switches on rear of beam detector•Special version available to work with external power supply if multiple beam detector to be connected to a single zone•IP40 protection •Beam detector has 3 modes of operation-Prism targeting mode - designed to provide simple initial alignment of beam and reflector assembly-Alignment mode - Enables accurate fine tuning of beam alignment without the need for additional calibration equipment or a second operator-Normal running mode INTERFACE OPTIONS •Conventional versions are designed to be directly connected toMenvier or JSB conventional panels•Analogue versions can be connected to suitable Menvier or JSBanalogue panels INSTALLATIONNOTES
