Carefully align the pins on the MPS-400 board with the connector
on the 4XTM board.
3
Press firmly on the 4XTM board until the board locks in place on
the standoffs.
4
Screw the 4XTM board to the standoffs.
Push the disconnect switch down to prevent unwanted activation of the
Municipal Box during testing of the control panel.
The Disconnect LED lights while the Municipal Box is disconnected; and
The System Trouble LED lights to indicate disconnected and/or open
circuit conditions on the Municipal Box.
During trouble conditions, you can transmit a trouble indication (through an
open circuit signal) on the Alarm Reverse-Polarity output. Do this by cutting
the TBL jumper shown in the following drawing.
