FIG 21
This function allows new devices/zones to be added to the system.
When a zone is added then the panel uses the next zone number and adds it to the zone list.
When a new device is added then the panel asks which loop the device is connected to and the scans
the loop looking for a reply of 254, once this reply is received that device is allocated the next
available address location, this process is then repeated for the next device to be added. It is not
possible to add more than one device at a time as multiple replies of 254 would be received at the
same time and the panel would try to address them all with the same location number.
Once a device has been added then it will be placed in zone 1, it then needs to be assigned to the
correct zone and have text inserted.
Sounders and I/O units can be added but on the older software will not operate so these needed to be
programmed by site installer. Version 2.4.25 addresses the issue.
Note. In all instances of an Add device the panel must receive a Watchdog reset for the device
to work correctly.
When zones/devices are deleted then a list of available zones/devices is displayed and the one to be
deleted is selected and then the panel removes that zone/device.
When a Zone is deleted all devices in that zone are also deleted (a warning is displayed on the panel
to this effect).
If a device is deleted the panel returns the address number back to 254 enabling the device to be re-
used
Delete/Add Device cannot be used on address 1 of loop 1, the panel must ALWAYS have a
device at this point.
