NOTICE!
Use the Cross Point function on non-fire points only.
The Cross Point option reduces false alarms. Points can be programmed so that the control
panel needs to see an Alarm condition within a programmed period of time (called Cross
Point Time) from at least two points within a Cross Point Group (Table 38) before Cross Point
Alarm Events are generated. These points must have P## Cross Point set to Yes to generate
this event.
There are 31 Cross Point Groups in the D9412GV4 and ten in the D7412GV4. Each Cross Point
Group consists of eight points and is identified by the point numbers in them (for example,
Cross Points 1 to 8, Cross Points 9 to 16, and so on). The maximum number of points that can
be programmed to meet the Cross Point criteria is two. Point numbers from different Cross
Point Groups do not affect each other. Refer to Table 5.3, Page 151 for a complete listing of
Cross Points comprising each Cross Point Group.
When any point with P## Cross Point set to Yes detects an alarm condition, the control panel
starts a timer as programmed in the Cross Point Time prompt.
If a second Cross Point within the same Cross Point Group detects an alarm condition, the
control panel creates a Cross Point Alarm Event for both points, provided both points activate
inside the Cross Point Window. A Cross Point is considered to be in alarm when it meets the
criteria for Instant Alarm response. The Cross Point index must have P## Pt Response set to a
value that generates an instant alarm response.
If a single Cross Point detects an alarm and stays faulted throughout the duration of the Cross
Point Window, a standard Alarm Report is generated for that point.
Conversely, if a single Cross Point detects an alarm, then restores, and no other conditions
occur, an Unverified Event is generated for that point. A second alarm on the first point does
not create an Alarm Event but rather an Unverified Event.
