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 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).
7. Make sure to
close the front cover plate
before powering the system from main AC supply.
The best way to set up a panel for the first time is to avoid connecting any field wiring at first. To begin set up, power
up the panel with an end of line resistor. The panel should be free of trouble. If the panel is free of trouble, connect
one circuit at a time, checking for troubles each time. If a trouble occurs at any point during the setup, correct the
fault, then continue the field wiring.
Power-up procedure
After completing the System Checkout procedures outlined above,
8. 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.
9. 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 I4 (located at the left
bottom of panel, near the trouble relay).
10.Configure the Fire Alarm Control Panel as described in the Configuration section.
Troubleshooting
Note:
Green LED I4 is illuminated when the system is normal. This LED indicates that the trouble relay is in
normal standby condition.
Symptoms
Possible Cause
Circuit Trouble
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 that the Circuit Disconnect Switch is in the ON or
CLOSED position.
Note: Disconnecting a Circuit will cause a system trouble (off-normal position).
Remote Trouble
Remote
Trouble will be indicated on the main panel 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.
Walk Test Mode
If the Walk Test LED is illuminated steadily, the system is in Walk Test Mode.
Common Trouble
If only a common trouble is indicated on the main panel and none of the above confirming
trouble indicators are on, check the following for possible fault:
• Check for any missing interconnection wiring.
• Check for any Module missing that was part of the Configuration.
• Check for improperly secured cabling.
