Push the Disconnect Switch (Figure 2-26) down to prevent unwanted activation of the
Municipal Box during testing of the control panel.
• The 4XTM Disconnect LED lights while the Municipal Box is disconnected; and
• The CPU 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
(Figure 2-26). Figure 2-26 shows connections to the 4XTM with polarities shown in
the activated position:
