Connecting control unit and fire panel
NOTICE!
i
To connect the MPA External detector alarm display and to trigger an alarm at MAX ALARM as
well as at DIFF ALARM, the dip switch 22 must be set to ON and the MPA must be connected
to the potential-free contacts 17-19.
Use potential-free contacts 11-19 to transmit alarm and trouble messages to the fire panel.
Remember that in normal mode, the fault relay is active and the contact between 11 and 12 is
therefore closed.
