11.2 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 5.8 if using SD devices or
Section 5.6 if using SK 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
5.7 if using SD devices or Section 5.5 if using 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 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 5.7 if using SD devices or Section 5.5 if using
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 5.7 if using SD devices or 5.5 if using SK devices.
