Alarm Silence.
In the following example, M2-1-1 is a monitor point on the 4100’s XA
card. It is linked to XA Device 2 (a switch) on the Autocall system. When XA Device 2 turns
ON, the input activates, which executes the following equation. (P217 is the Network Signal
Silence pseudo point on the FACP.)
IN:
M2-1-1 ON
OUT:
TRACK ON P6 PRI = 9,9
Status points are
logical
fire and trouble points on the FACP XALIC card. The status (on or off)
of these points is controlled by Custom Control equations on the FACP. The function of a status
point is to signal a change in the state of a FACP point to the Autocall head end. For example, a
Custom Control equation could be written to monitor the state of L256, which is the list in which
all points with the FIRE point type are placed. When any device in this list enters an alarm state,
the Custom Control turns ON subpoint 5 for one of the XALIC status points. (For any given
XALIC status point, subpoint 5 is always the fire point and subpoint 6 is always the trouble point.)
This triggers the corresponding XA device at the Autocall head end to turn on as well.
Each FACP XALIC Status 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 Autocall side of the loop. The
Subpoint
used with a status point is always either 5 (alarm status subpoint) or 6 (trouble status
subpoint).
