Installation
Local Energy Municipal Box Service (NFPA 72 Auxiliary Fire Alarm Systems):
Supervisory Current: 5.0 mA
Trip Current: 350 mA (subtracted from notification appliance power)
Coil Voltage: 3.65 VDC
Maximum Coil Resistance: 14.6 ohms
Maximum allowable wire resistance between panel and trip coil: 3 ohms
Municipal Box wiring can leave the building
Remote Station Service (NFPA 72 Remote Station Fire Alarm Systems) - Intended for connection to a polarity reversal circuit or
a Remote Station receiving unit having compatible ratings:
Maximum load for each circuit: 10 mA
Reverse polarity output voltage: 24 VDC
Remote Alarm and Remote Trouble wiring can leave the building
Before installing the module, place the disconnect switch to the right (disconnect) position to prevent accidental activation of the munic-
ipal box. Note that a Disconnect LED will illuminate after the module is installed in the NFW-100X. In addition, the System Trouble
LED will turn on to indicate the Disconnect condition.
The following steps must be followed when installing the 4XTM module:
1.
Remove all power (Primary and Secondary) from the FACP before installing 4XTM
2.
Carefully plug the connectors on the 4XTM module into connectors J12 and J13 on the NFW-100X main circuit board, being
careful not to bend any pins.
3.
Secure 4XTM module to standoffs with supplied screws.
4.
Slide SW2 on the NFW-100X main circuit board to the down position.
5.
Enable 4XTM supervision in user programming. Refer to "4XTM Supervision" on page 80.
6.
Reapply power to the FACP.
7.
For proper 4XTM operation, the output relays must be programmed for the factory default settings: Alarm Relay 1, Trouble Relay 2
and Supervisory Relay 3.
8.
When the installation has been complete, enable the 4XTM module by sliding the disconnect switch to the left.
9.
Test system for proper operation.

Note: The 4XTM Module is not directly suitable for transmitting a reverse polarity
supervisory signal. For applications using reverse polarity of a supervisory signal, refer to
"FACP with Keltron" on page 143.
