12.1 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 Honeywell Technical Support for assistance.
12.2 Troubleshooting Common Problems
Problem
Trouble message "DBL ADDR"
(Double Address) displays on LCD.
Auxiliary power or notification circuits
have incorrect polarity.
SLC devices are not being recognized
(trouble message "Missing" displays).
SLC devices are not being recognized
(trouble message "Missing" displays on
the annunciator).
5496 module that has been physically
connected to the panel but is not being
recognized.
12.2.1 Periodic Testing And Maintenance
To ensure the 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.

Section 12: Testing and Troubleshooting
An address has been assigned to more than one detector. Correct the address following the
procedure described in Section 7.7 for SK & IDP devices or Section 7.9 for SD devices.
For additional information on IDP, SK and SD SLC devices, refer to Section 7.
Correct polarity. For notification and auxiliary power circuits: When in alarm or powered, terminals
labeled "X" are positive, terminals labeled "O" are negative.
Check hardware connections. If devices are physically connected, make sure wiring is correct (see
Section 7.6). For the main panel, the positive side of 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 following the procedure described in
Section 7.
For contact monitor modules, which are addressed using DIP switches, the DIP switch must be set
to the correct address before power is applied to the SLC loop. If this procedure is not followed, the
device will have an incorrect address.
Make sure correct polarity has been observed for SLC device wiring. See Section 7.
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 40 ohms.
Check the status of the 5496 green LED. If it flashes in the pattern.5 sec. on /.5 sec. off, it is likely
that the 5496 has not been added to the system through programming. JumpStart will add any
5496s connected to the panel. If you have already run JumpStart, 5496s can be added manually
(see Section 8.2.2).
Check that the correct ID for the 5496 module has been set through the DIP switches. Assign ID#1
to the first 5496 and ID#2 to the second 5496. See Section 4.11.1 for complete details.
If the wiring between the 5496 and the panel is correct, measure the voltage from 5496 Terminal (+)
to Terminal (-). Voltage should be in the range 27.2-27.4V when AC power is present.
If the green LED is not flashing, the likely cause is incorrect wiring from between the 5496 and the
panel. See Section 4.4 for wiring details.
