INSTALLATION INSTRUCTIONS
Model FS-MT
Municipal Tie Module
The FS-MT Municipal Tie module is an optional module for the FS-250 and FS-250C Fire Alarm System
Control Panels. The FS-MT provides local energy and polarity reversal connections. The polarity reversal
connections provide a trouble circuit and an alarm circuit with optional trouble output. The FS-MT module
is mounted on the Main Termination Board. The trouble outputs of the two polarity reversal circuits are
interconnected and the control unit may be programmed to send trouble, supervisory or either.
PARTS SUPPLIED
1 FS-MT module
4 Spacers, 1”
1 Keps Nut, #6-32
1 3.9K ohm E.O.L. Resistor Assembly (P/N 140-050008-2)
1 Instruction Sheet
Step 1.) Installation is to be done by qualified personnel
who have thoroughly read and understood this
instruction sheet.
Step 2.) Disconnect BATTERY and AC prior to working on
equipment.
Step 3.) Set jumper J2 for proper operation.
J2 – REVERSE POLARITY ALARM CIRCUIT
 ALARM

 ALARM WITH TROUBLE
When J2 is set at “Alarm With Trouble”, the “CA”
terminals will measure 0 VDC when trouble is
detected and no alarm is present on the system.
Step 4.) Mount FS-MT as shown, using four spacers to the
Main Board.
NOTE: Check to see that the header and
connectors are mated properly.
Step 5.) Attach ground wire as shown, using #6-32 Keps
Nut to backbox stud.
For the FS-250 or FS-250C use the nearest main
board mounting screw as shown.
Step 6.) If the local energy circuit is not used, connect the
3.9K ohm E.O.L. Resistor Assembly (P/N 140-
050008-2) across terminals LE1 and LE2.
Step 7.) Attach conduit and run wires as required.
Step 8.) Connect wires to the fire alarm system control unit
as required.
Step 9.) Apply power to system.
Step 10.) Program for proper operation of functions.
a) Tech Level>>Outputs>Option Mods>City Tie
(Set City Tie status to Installed)
b) Tech Level>>Sys Params>CityTrbActvn
(Set City Tie trouble activation to Trb, Sup or Either)
c) Maint Level>>Disable/Enable>Outputs>City Tie
>Enabled
NOTE: See Programmer’s Manual (P/N 315-049403 for
FS-250 or P/N 315-049403C for FS-250C) for more
details on programming.
Step 11.) Check for proper operation of functions.
