XPIQ-SLI Wiring Style 4 With Degraded Mode
An XPIQ-SLI, wired Style 4 and configured for degraded mode operation, is illustrated in Figure 2.21 and
Figure 2.22. The initiating devices that are compatible with degraded mode are the FSI-751, FSP-751,
FMM-1 and XP5-M.
The FMM-1 monitor modules must have
terminals 3 and 4 jumpered and XP5-M
switches SW201, SW202, SW203, SW204
and SW205 must be on to enable the
degraded mode operation. Refer to the
documentation supplied with each device for
additional information.
Degraded mode operation allows for
detection of alarm conditions on the local
branch in the event that communication is
lost between the XPIQ and FACP. When the
XPIQ-SLI detects loss of the SLC signal, it
disconnects the local branch from the SLC and monitors the local branch smoke detectors and monitor
modules for an alarm condition. Once an alarm is detected, the XPIQ will automatically send an evacuation
tone from the local tone generator (tone generator #1) to all local speaker zones and it will close the alarm
contacts on TB3. These contacts may be connected to a separate circuit monitored by the FACP. This type of
alarm state is nonlatching and will clear once the local branch devices return to the normal (standby) state.
The control modules installed on the local branch will not be controlled and will remain in the state they were
in prior to the loss of SLC communication. The SLC devices located on the local SLC branch are not
supervised during degraded mode of operation. The degraded mode of operation is solely intended for
enabling alarm detection before qualified personnel arrive to service the system.
