The MIO module is the input/output device intended for the co-operation between conventional detectors and AWEX Fire Alarm Control Unit. It can operate on the detection loops or stub detection circuits. Module can work with conventional smoke detectors, conventional multisensory detectors and conventional manual call points. MIO22 CD has 2 outputs dedicated for conventional lines and 2 monitoring inputs (NO/NC contact). Device is equiped with double-sided short-circuit isolator. These ensure constant loop working, even in case of damage. It also lets you find place of that damage easily.
