Installation of Optional Modules
NAC-REM (NAC/Relay Expander Module)
The NAC-REM Module can be used to add two Style Y (Class B) or Style Z (Class A) NACs (1.5 amps maximum
each) and two Form-C relays to the MS-5210UD. Connector J1 of the NAC-REM module plugs into connector J7
which is located at the top left corner of the MS-5210UD main circuit board.
Install the two supplied metal standoffs into the FACP main circuit board. Ensure that the metal standoff is
installed in the position indicated in Figure 2-12. Carefully align the two connectors and press the NAC-REM
module securely into place. Make certain the pins are properly aligned to prevent bending or breaking of any pins.
It is important that the supplied screw and washer be used to secure the module to the metal standoff. This is nec-
essary in order to help protect against electrical transients.

PRT-24 Printer Interface Module
A remote printer may be permanently or temporarily connected to provide a hardcopy printout of normal current
system status and activity, program entries, history file, troubleshoot mode voltages and walktest data. The
PRT-24 provides an EIA-232 conversion to adapt to most 40 and 80 column printers.

CAUTION: DO NOT connect a printer to the Fire Alarm Control Communicator if a ground fault exists on the
panel. Circuit damage may result.
