Shop Interface Unit
The operation and functions described in this manual are available from Software Version 4000-016-00 onwards.
Features
The Shop Interface Unit allows MxPro 4 control panels to send and receive alarm signals from other
equipment.
Input signals can be received from clean-contact inputs, with two of the inputs also supporting open circuit
and short circuit fault monitoring on the external wiring.
A special input is also able to differentiate between an input that is pulsing (ALERT) or is on continuously
(EVAC), allowing easy interfacing to older equipment that cannot provide independent Alert and Evacuate
signals.
Two fully programmable outputs are also provided to allow signals to be transmitted out to other equipment.
