Note, the Advent xt controller must be reset for it to detect a telephone handset has been connected.
DUAL HANDSETS
Normally only one telephone will be connected per channel, if a flat requires a second handset then both telephones

both ZFT220 telephones. The second handset MUST have link LK3 moved to position “B” (slave) - it is not possible to have
more than 2 telephones per flat. For connection details see Tynetec Drg No. ZXT100 sheet 4.

Note; a maximum of 2 strobes per flat is permitted.
