The module is designed to connect 2-wire fire alarm loops to an intruder-fire CP as well as to a AC fire alarm CP.
MUSH-DL module is used with the ARTON-DL beam detector.
MUSH-DL issues the Alarm signal when ARTON-DL detector activates and the Fault signal when an optical channel is fully overlapped, short-circuit or 2-wire open-circuit occur.
The module is connected to FACP and 2-wire loop with cross blocks. A signal loop of FACP and EOL resistor should be connected to screw contacts “1”, “2”, “3”. 12V FACP power source should be connected to screw contacts “4”and “5”. Detectors should be connected to screw contacts “6” and “7”.
