The Autocall head end can control physical or logical points on the FACP, allowing the head end
to perform a range of functions on the FACP such as on/off, system reset, signal silence, etc.
These types of points are called
Control points
. See “Programming Control Points” in this
section for more information.
The FACP’s XALIC can also be configured to report status to the Autocall head end for up to 250
FACP devices. These types of points are called
Status Points
. See “Programming Status Points”
in this section for more information.
Note:
When the FACP functions as a slave to the Autocall panel, it is different than most
master/slave situations. The FACP continues to monitor and control all devices that are
not associated with an XALIC point and can operate completely independent of the
Autocall panel.
A Control Point is a logical input point on the FACP XALIC card that serves as a trigger for a
FACP Custom Control equation (for example, reset, silence, LED annunciation, NAC signaling,
etc.). Each control point on the FACP corresponds to a physical or logical output point on the
Autocall head end. When the head end turns on the output point, the corresponding FACP XALIC
input turns on, and the FACP custom control equations execute.
Each FACP XALIC Control Point address consists of three parts: the MAPNET
®
channel
number, the XA Loop Device Number, and the Subpoint. The
MAPNET channel
number is
automatically assigned to the XALIC card at installation time. It can be any number between 1
and 30 and is always preceded by an M. The
XALIC Device Number
is a number between 1 and
250. It corresponds directly to the matching XA device address on the AUTOCCALL side of the
loop. The
Subpoint
used with a control point is always 1.

Use the three-step process detailed below to program a control point.
Step 1. Identify and Map Addresses.
Before programming Control Points, it may be helpful to list the XALIC control points and the
Autocall device numbers, along with the function of the point or device, in a spreadsheet format.
