7.4.4 Replacing a radio device with another of the same type
The procedure for replacing radio devices on a detector line is no different to the
one used for replacing wired devices. The relevant fire detection system
documents also apply to the SWING radio fire detection system.
If you replace a radio device with another device of the same type, the system
should not change; only the radio device identification information will need to be
altered.
If you want to replace multiple radio devices, you must finish replacing one device
before you start replacing the next one.
This will ensure that the site configuration does not change.
