38 Amended: April 22EMEA Fire Technical Support: DF6000/CF3000 Applications GuideAdd/Delete.Fig 27This 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 scansthe loop looking for a reply of 254, once this reply is received that device is allocated the nextavailable address location, this process is then repeated for the next device to be added. It is notpossible to add more than one device at a time as multiple replies of 254 would be received at thesame 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 thecorrect 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 beprogrammed 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 deviceto follow the output programming.When zones/devices are deleted then a list of available zones/devices is displayed and the one to bedeleted 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 panelto this effect).If a device is deleted the panel returns the address number back to 254 enabling the device to be re-usedDelete/Add Device cannot be used on address 1 of loop 1, the panel must ALWAYS have a device atthis point.
