Secondary Zones
The Program Part / Test /Chime option has now been renamed to Program Zone
Attributes. Within this section you are able to allocate zones as Secondary Zones.
Secondary type zones would be used for detectors that may be deemed as having an
over sensitive nature, this will stop unwanted user call-outs. Zones that are entered as
Secondary will follow the chain of events below.
During a set period triggering a Secondary Zone will start the Secondary Time
Window. This will be logged but no further action is taken. If the second zone to alarm
during the same set period is also a Secondary Zone then it will be logged and the
Secondary Time Window will be restarted.
If the time set within the Secondary Time Window is still running and a zone that is not
allocated as a Secondary Zone is triggered the event will be logged an Alarm A (un-
confirmed) and Alarm B (confirmed) will be transmitted.
This feature is not mandatory for BS8243.
Comms Restore
With Comms Restore turned on any outstanding alarm channels will be restored at the
end of the Confirm Time Window.
This feature is mandatory for BS8243
Perimeter Zones
Within the Program Zone Attribute section you are able to allocate zones as Perimeter.
Zones that are entered as Perimeter will follow the chain of events below.
When activated an unconfirmed alarm will be transmitted to the central station. An
output or digi channel may be programmed as perimeter (or if using Point ID a new
signal type of perimeter will be sent). This will allow central station to inform the
keyholder that an unconfirmed alarm has been received and is a perimeter type device
i.e window backdoor etc. etc. This feature is not mandatory for BS8243.
Scenarios Relating to BS8243.
Sounder / Bell Considerations
Please note careful consideration should be given when programming Confirm
Sounder and Confirm Bell Modes. If both are programmed for confirmed and any of the
above scenarios occur no local sounders will activate.
