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 DD243
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 DD243.
Scenarios Relating to DD234.
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.
Other DD243 Notes to Consider
When a system auto re-arms with a zone in fault condition The GardTec control panel
will omit the zone concerned. A signal should be sent to the central station indicating
that a detector(s) has (have) been isolated. To achieve this a Digi channel should be
programmed as Zone Exclude, this will automatically send the required signal as the
detector is omitted.
Output Option (Status)
This option has three operating modes and is intended to provide a visual indication of
the system status.
System Set
Output On for 10 seconds
System Unset Output On for 1s Output Off for 1s for a 10 second
period
Confirmed Alarm Output On for 3 seconds Output Off for 1s until
system reset.
It is envisaged that this status output would be fitted to an indicator (i.e. LED) that can
be seen from outside the premises.
