VISTA-50P/VISTA-50PUL Installation and Setup Guide
Cross-Zoning
Cross Zoning is designed so that a combination of two zones must be faulted within a 5-minute period of each other
(whereas the first zone remains faulted, when the second zone trips) to cause an alarm on either zone. This prevents
momentary faults from one of the zones from causing an alarm condition. You can select four "sets" of cross-zones
(programmed in data fields 1*22, 1*23, 1*24, and 1*25), keeping in mind the following:
•
Both zones in each set must protect the same area.
•
When cross-zoning motion sensors, both device's areas of protection must be situated so that both units will trip at
the same time if their shared protected area is violated.
•
Both zones in each set must be in the same partition.
•
A fire zone must only be crossed to another fire zone protecting the same physical area (see warning below).
DO NOT cross-zone a fire zone with a burglary zone under any circumstance. Cross a fire zone with another fire
zone only, and BOTH must be protecting the same physical area (no walls or partitions separating them). Consult
NFPA 72 standard for exact spacing requirements. We recommend that spacing between fire cross-zones be no
farther than 30 ft.
Conditions That Affect Cross-Zone Operation
•
If one of the zones in a pair is bypassed or has a zone response type set to 0, the cross-zoning feature does not apply.
•
If an entry/exit zone is paired with an interior follower zone, be sure to enter the entry/exit zone as the first zone of
the pair. This ensures that the entry delay time is started before the follower zone is processed.
•
If a relay is programmed to activate on a fault of one of the zones, the relay activates without the other zone being
faulted.
•
If a relay is programmed to activate on either an alarm or trouble, both zones must trip before the relay will
activate, and both zones must restore for the relay to deactivate (if relay is programmed to deactivate on a Zone List
Restore).
If the one of the zones trips and the second zone does not trip within the 5-minute period, an "error" message is
reported to the central station. The Contact ID event code is 378.
