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 Silent Knight Technical Support at 800-328-0103 or 763-493-6455 for assistance.
12.2 Common Problems
Problem Possible Cause / Suggested Actions
Trouble message "DBL ADDR" (Double
Address) displays on LCD. An address has been assigned to more than one detector. Correct the address
following the procedure described in Section 7.5 if using IDP devices
Auxiliary power or notification circuits
have incorrect polarity. Correct polarity. For notification and auxiliary power circuits: When in alarm
or powered, 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 wiring is correct (see section
7.4 if using IDP devices). For 5815XL devices, make sure the device connects
to the 5815XL via the SLC OUT terminals.
There can be only one SLC loop on the main panel and on each 5815XL
module. Do not connect devices to terminals labeled SLC IN.
Make sure SLC devices have been addressed properly following the
procedure described in Section 7.5 if using IDP devices.
Make sure correct polarity has been observed for SLC device wiring. See
Section 7.4.
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.
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.
The panel indicates a ground fault trouble
condition (trouble message "GROUND
FAULT" displays). 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.
