Before Turning the Power On
1. To prevent sparking, do not connect the batteries. Connect the batteries after powering the system from the
main AC supply.
2. Check that all modules are installed in the proper location with the proper connections.
3. Check all field (external) wiring for opens, shorts, and ground.
4. Check that all interconnection cables are secure, and that all connectors are plugged in properly.
5. Check all jumpers and switches for proper setting.
6. Check the AC power wiring for proper connection.
7. Check that the chassis is connected to EARTH GROUND (cold water pipe). Refer to NFPA 70.
8. Make sure to close the front cover plate before powering the system from main AC supply.
Note: When using Class A and isolators on an addressable loop, configure system as Class B, wire loop as
Class A, except do not connect the last device back to the panel. Do a system checkout. Then
connect the return of the Class A circuit and configure as Class A.
Power-Up Procedure
1. After completing the above procedures, power up the panel (AC only). The green AC On LED and the Common
Trouble LED should illuminate, and the buzzer should sound.
2. Press the System Reset button. Since the batteries are not connected, the Battery Trouble LED should
illuminate, the trouble buzzer should sound intermittently, and the Common Trouble LED should flash.
3. Connect the batteries while observing correct polarity: the red wire is positive (+) and the black wire is negative
(-). All indicators should extinguish except for the AC On LED and the LCD should show a normal status
condition.
4. Auto-Configure or PC Configure the fire alarm control panel as described in the Configurator Guide.
Troubleshooting

Normally when a circuit trouble occurs, its designated trouble indicator will be illuminated,
as well as the Common Trouble indicator and Trouble buzzer. To correct the fault, check
for open wiring on that particular circuit loop or see if the circuit disconnect switch is in the
ON or CLOSED position. Note: disconnecting a circuit will cause a system trouble (off-
normal position).
The FX-2000N panel has a Common Ground Fault Detector. To correct the fault, check for
any external wiring touching the chassis or other earth ground connection.
Check for the presence of batteries and their condition. Low voltage (below 20.4V) will
cause a battery trouble. If battery trouble condition persists, replace the batteries as soon
as possible.
