4. Set the AC input voltage selector switch located near the bottom right of the
controller for either 120 or 240 Vac input voltage. Push the switch up for 120 Vac or
down for 240 Vac. Route two 12 AWG wires between the fused disconnect and the
AC input at JP22. (See Figures 4 and 5.)
5. Route a 6 AWG ground wire from the earth grounding rod to the FC Controller
cabinet ground stud.
6. Route a 1/2-inch conduit between the conduit fittings on the bottom of the FC
Controller cabinet and the siren motor starter cabinet, or alternatively to other
equipment.
NOTE: The following wiring is for the RC2W motor starter. For the 2001-AC wiring, see the
2001-AC manual.
7. Route two 12 AWG wires between JP21 on the FC circuit board and the siren motor
contactor as follows: (See Figures 4 and 5.)
• Connect one wire between JP21-1 of the FC control and terminal 95 of the RC2W
motor starter.
• Connect one wire between JP21-2 and L1 of the RC2W motor starter.
8. If the siren is to be controlled remotely through a momentary contact closure, apply
the contact closure to the appropriate input on JP10. The wire run from the contact to
JP10 must not exceed 50 feet (15.24 meters). If longer wire runs are required, you can
purchase a model TRC1020 for each function. The inputs on JP10 require 1-second
contact closures.
