XPIQ PN 51013:C 7/01/03 19
1.6.4 XPIQ-SLI Signaling Line Interface Board
The XPIQ-SLI board provides data communication interface between the XPIQ-MB and the SLC
(Signaling Line Circuit) of an FACP (Fire Alarm Control Panel). This board acts as a collection of
control modules and is designed to use either CLIP protocol or the FlashScan protocol. The
number of addresses utilized by the XPIQ-SLI depends on the number of channels, speaker zones,
telephone zones and other options selected during configuration by the installer. Two rotary
switches are used to set the starting address of the board. A seven-segment display is used to
indicate the address range used, when the address verification push-button (SW2) is pressed. The
routing of the audio channels to speaker zones is implemented by activating SLC output points in a
matrix programmed in the XPIQ. The rows of this matrix represent audio input channels and the
columns of this matrix represent speaker circuits. Refer to Table 2.4 through Table 2.19.
The XPIQ-SLI can be wired to the SLC in Style 4, 6 or 7. When configured for Style 4 wiring, the
XPIQ-SLI can be utilized to take advantage of the unique degraded mode operation that takes place
when SLC communication with the FACP is lost. When in degraded mode, the XPIQ-SLI
monitors specific FlashScan detectors/monitor modules and automatically activates the evacuation
signal on all speaker zones when an alarm state is detected. Separate alarm contacts on TB3 can be
used as an alternate way of communicating a local alarm condition during degraded mode back to
the FACP. (See TB3 inset in the figure below.)
