Section 9: Testing and Troubleshooting
9.1 Troubleshooting
This section of the manual offers suggestions for troubleshooting hardware problems. Please read this section if you encounter a problem
when you install the fire alarm control panel. If these suggestions do not solve your problem or if you encounter a problem that is not listed,
contact Gamewell-FCI technical support for assistance.
9.2 Troubleshooting Common Problems
9.2.1 Periodic Testing And Maintenance
To ensure proper and reliable operation, it is recommended that the System inspection and testing be scheduled monthly or as required by the
national and/or local fire codes. Testing should be done by a qualified services representative if a malfunction is encountered.
Before testing:
1.
Notify the fire department and/or the Central Alarm Receiving Station if an alarm condition is transmitted.
2.
Notify the facility personnel of a test so that the alarm sounding devices are ignored during the test period.
3.
When necessary, activation of notification appliances can be prevented by the DISABLE function.
Testing:
1.
Activate an input via an alarm initiating device and check that the correct outputs activate (notification appliances sound/flash, relays
activate, alarm LED lights). Reset the system. Repeat for each alarm initiating device.
2.
Momentarily open the following circuits one at a time and check for a trouble signal:
• notification appliance (bell) circuits
• initiating devices
3.
If new batteries were installed, wait 48 hours before completing this step. Remove the AC power, activate the initiating device, and
check that the following occurs:
• The ALARM indicator lights.
• All active notification appliances sound.
Measure the battery voltage while the notification appliances are sounding. Replace any battery with terminal voltage less than 85% of rat-
ing. Reapply the AC power and reset the system.
9.2.2 Event History
The event history can be useful for tracking or recalling a trouble condition.
To view event history:
1.
Login to the panel.
2.
Press 3 to select Event History.
3.
Press the up or down arrow key to view events in the history buffer.
Problem
Possible Cause / Suggested Actions
Trouble message “DBL ADDR” (Double
Address) displays on LCD.
An address has been assigned to more than one detector. Check detector addresses for duplications.
For information on setting the SLC address, refer to the
SLC Wiring Manual
.
Auxiliary power or notification circuits
have incorrect polarity.
Correct polarity. For notification and auxiliary power circuits, terminals labeled “X” are positive, terminals
labeled “O” are negative.
SLC devices are not being recognized
(trouble message “Missing” displays).
Check hardware connections. If devices are physically connected, make sure the wiring is correct.
For more information on SLC wiring, refer to the
SLC Wiring Manual
.
For the main panel, the positive side of the device must be connected to Terminal 34; the negative side must
be connected to Terminal 33. For SLC devices, make sure the device connects to the SLC loop via the SLC
OUT terminals.
Make sure SLC devices have been addressed properly.
For information on the procedure to set the SLC Devices addresses, refer to the
SLC Wiring Manual
.
Make sure the correct polarity has been observed for SLC device wiring.
For more information on SLC devices, refer to the
SLC Wiring Manual.
SLC devices are not being recognized
(trouble message “Missing” displays on
the annunciator).
Check that SLC loop impedance is within the required range.
To measure impedance, use the following procedure.
Disconnect both wires from the terminal block at the panel (SLC devices can remain connected).
Measure the impedance from positive to negative and from negative to positive. Both measurements should
be greater than 500 K ohms. If the installation uses T-taps, test each T-tap individually.
Temporarily connect the positive wire to the negative wire of the SLC loop at the point farthest from the panel
(SLC devices can remain connected).
Measure the impedance from positive to negative and from negative to positive. Both measurements must be
less than 50 ohms.
