12.1 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 Silent Knight Technical Support at 800-446-6444 for assistance.

Section 12: Testing and Troubleshooting

An address has been assigned to more than one detector. Correct the address following the
procedure described in Section 7.9 is using SD devices or Section 7.8 if using SK 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 7.5). 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 7.8 or Section 7.9. 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. Section 7.9 is using
SD devices or Section 7.8 if using 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 remain
connected)
2. 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.
3. 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).
4. Measure the impedance from positive to negative and from negative to positive. Both
measurements must be less than 50 ohms.
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 USB. 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
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
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 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.
