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
5.3). 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 5815
devices, make sure the device connects to the 5815 via the SLC OUT
terminals.
There can be only one SLC loop on the main panel and on each 5815 module.
Do not connect devices to terminals labeled SLC IN.
Make sure SLC devices have been addressed properly following the
procedure described in Section 5.10.
For contact monitor modules, which are addressed using dipswitches, the
dipswitch 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 5.3.
