FA-300 Series LCD Version Installation and Operation Manual

System Checkout

Before turning the power “ON”

To prevent sparking, do not connect the batteries. Connect the batteries after powering the system from the main

AC supply.

1. Check that all modules are installed in the proper location with the proper connections.

2. Check all field (external) wiring for opens, shorts, and ground.

3. Check that all interconnection cables are secure, and that all connectors are plugged in properly.

4. Check all jumpers and DIP switches for proper setting.

5. Check the AC power wiring for proper connection.

6. Check that the chassis is connected to EARTH GROUND (cold water pipe).

Power-up procedure

After completing the System Checkout procedures outlined above,

7. Power up the panel. The "AC-ON" green LED and the “Common Trouble” LED should illuminate, and the

buzzer should sound. Press the “System Reset” button. Since the batteries are not connected, the trouble

buzzer should sound intermittently and the common trouble LED should flash.

8. Connect the batteries while observing correct polarity: the red wire is positive (+) and black wire is negative (-).

All indicators should be OFF except for normal power "AC ON" green LED and green LED I47.

9. Configure the Fire Alarm Control Panel as described in the Configuration section.

Troubleshooting

Note: Green LED I47 is illuminated when the system is normal. This LED indicates that the trouble relay is

in normal standby condition.

Symptoms

(as displayed

on the LCD)

Possible Cause

Circuit Trouble

Normally when a circuit trouble occurs, the common trouble indicator will illuminate and trouble

buzzer will sound. To correct the fault, check for open wiring on that particular circuit loop (as

displayed on the LCD) or that the circuit has not been disconnected (or bypassed).

Disconnecting a Circuit will cause a system trouble (off-normal position).

Remote Fail

Remote Fail will be indicated on the main LCD display for any failure reported by, or failure to

communicate with a remote annunciator or other remote device.

Ground Fault

This panel has a common ground fault detector. To correct the fault, check for any external

wiring touching the chassis or other Earth Ground connection.

Battery Trouble

Check for the presence of batteries and their conditions. Low voltage (below 20.4V) will cause

a battery trouble. If battery trouble condition persists, replace batteries as soon as possible.

Common Trouble

If only a common trouble is indicated on the main panel and none of the above troubles exist,

check the following for a possible fault:

Check for any missing interconnection wiring.

Check for any Module missing that was part of the Configuration.

Check for improperly secured cabling.
