Exit Delay Reset; Cross Zoning - ADEMCO VISTA-128B Installation And Setup Gude

VISTA-128B Installation and Setup Guide

Exit Delay Reset

U L
This feature is not suitable for use on a UL commercial burglary installation.
This feature is designed to allow an operator to re-enter the premises to retrieve a forgotten
item without triggering an alarm. This feature is enabled in program field 1*21, and works
in the following way:
When the panel is armed, the normal exit delay begins. After the user exits and the door
closes, the exit delay time is reset to 60 seconds. If, within this 60-second period, the entry
door is re-opened, the panel will restart the exit delay sequence using the programmed exit
delay time. This feature will only be activated once after arming.

Cross Zoning

U L
This feature is not suitable for use on a UL commercial burglary installation.
The
Cross-Zoning
within a 5 minute period of each other to cause an alarm on either zone. This prevents
momentary faults from one of the zones causing an alarm condition. You can select four
"sets" of cross-zones, keeping in mind the following:
•
Both must protect the same area.
•
Both 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).
Note: The four sets of cross-zones are programmed in data fields 1*22, 1*23, 1*24, and 1*25.
DO NOT cross-zone a fire zone with a burglary zone under any circumstance. A fire zone must
only be crossed to another fire zone and BOTH must be protecting the same physical area (no
walls or partitions separating them). Consult NFPA 72 standard for exact spacing requirements.
As a guideline, we recommend that spacing between fire cross-zones be no farther than 30 ft .
Conditions That Affect Cross-Zone Operation
•
In the event of a continuous fault (lasting at least 5 minutes) on one of the paired zones, a
fault on the second zone will cause an alarm immediately.
•
If one of the zones in a pair is bypassed or has a zone response type set to 0, the cross-
zoning feature will 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 will ensure 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 will activate
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).
