FA2000C Installation and Setup Guide
Slip the bottom part of the circuit board onto the 3 lower Standoffs ensuring it is under the lock washers.
5
Then snap the top part of the circuit board onto the 2 upper Standoffs.
Tighten the 3 screws securing the circuit board to the 3 lower Standoffs.
6
Install the LED Indicator board and connect its cable to J5 on the printed circuit board.
7
ENSURE FACILITY POWER IS OFF.
8
Remove the Power Supply's cover plate (4 screws). Refer to Figure 2-3 and the Simplified Wiring Diagram
(inside of back cover) and install the earth ground connections.
Use wire nuts (not supplied) to connect the facility power wiring to the power supply transformer's black and
9
white wires. Replace the power supply cover plate.
Connect the transformer's 18VAC BLUE flying leads which emerge from the top of the enclosure to the
10
circuit board's AC terminals (Terminals 1 and 2). Replace the power supply cover plate.
The control panel requires connection to a good earth ground in order to provide proper 120VAC shock hazard
protection, lightening transient protection, and earth ground fault detection.
Refer to the National Electrical Code for proper earth grounding methods.
• A dedicated 120VAC circuit must be used for fire applications.
U L
• Wires must be rated for 90 degrees C or higher operation.
Make sure that the dedicated AC circuit is not powered at this time.
Apply AC power only after all other wiring, except the backup battery wiring, has been completed.
