F) For any types of handsets not listed
in table 7 the information is the
same as table 4 to table 6.
G) For all handsets which connect to
the same auxiliary power supply
the display can be switched on at
the same time.
Remark: if small entrance panels are present, the
number of devices to be supplied by 323010 may
require to use more power supplies, increasing
the project cost.
We therefore suggest to use 323005 to setting
auxiliary power supply.
