13.1 Troubleshooting

This section of the manual offers suggestions for troubleshooting hardware problems. Please read this section if you encounter a problem
when installing the control panel. If these suggestions do not solve your problem or if you encounter a problem that is not listed here,
contact Honeywell Technical Support at 800-446-6444 for assistance.
Common Problems:
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).
The panel indicates a ground fault trouble
condition (trouble message "GROUND
FAULT" displays).
5496 module that has been physically
connected to the panel but is not being
recognized.

Section 13: Testing and Troubleshooting

Problem
An address has been assigned to more than one detector. Correct the address
following the procedure described in Section Section 7.1 for IDP devices or
Section Section 7.2 for SK devices, & Section Section 7.3 for SD devices
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
Section 7.9 for SD devices and Section 7.7 for IDP or SK devices). 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 7.10for SD devices and Section 7.8 for IDP or SK devices.
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
7.9for SD devices and Section 7.6 for IDP or SK devices.
Check that SLC loop impedance is within the required range.
To measure impedance, use the following procedure.
1. Disconnect both wires from the terminal block at the panel (SLC devices can
2. Measure the impedance from positive to negative and from negative to positive.
3. Temporarily connect the positive wire to the negative wire of the SLC loop at
4. Measure the impedance from positive to negative and from negative to positive.
An earth ground fault occurs when the panel senses an unexpected flow of current
from one or more of its terminals to the earth connection (Terminal 2).
Isolate the wiring that is causing the fault by removing wiring connections one at a
time until the earth fault is no longer present. Pause at least five seconds after
removing a wire before removing the next one.
The panel will also go into ground fault if a computer is connected to the panel via
a serial cable attached to the panel's 9-pin connector or a USB cable. This is a
correct method for on-site communication between a panel and a computer. Ignore
the ground fault message in this case. The trouble will clear automatically when
you disconnect the computer from the cable

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 9.2.2).
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. 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.
Possible Cause / Suggested Actions

Both measurements should be greater than 500 K ohms. If the installation uses
T-taps, test each T-tap individually.
the point farthest from the panel (SLC devices can remain connected).
Both measurements must be less than 50 ohms.
