Zone Crossing

The Zone Crossing menu is used for additional protection from false alarms
and contains parameters that enable you to link together two related zones.
Both must be violated within a designated time period (between 1 and 9
minutes) before an alarm occurs.
This type of linking is used with motion detectors in hostile or false-alarm prone
environments.
NOTES:
The ProSYS allows 10 unique sets of zone links (pairs of zones), which can be
manually specified, as required. Zones crossed with themselves are valid pairs.
They need to register a violation twice to trigger the alarm. This process is known
as Double Knock. You may want to establish a number of zone links, but leave
them deactivated at this time (see below).

Not Ordered
Affects an alarm in which either zone in the pair may be tripped first. If this
case, the specified zone order (1st, 2nd) has no bearing on the alarm
activation.
7 After choosing one of the above, press / to define the maximum time-
lapse interval between 1 and 9. The Time Slot parameter appears:
8 Enter the time slot, meaning the maximum amount of time allowed between the
triggering events for them to be considered a valid violation (XX,YY indicate the
crossed zones).
O Default: 1 min
O Range: 1 to 9 minutes
9 Repeat the entire process, as required, for any additional zone links (up to 10).
