HTC 711-0 with integrated audio
privacy function, door release and
light button, electronic call signal
encoder with alpha, 3-tone call and
chime for the new 1+n (wire-saving)
system. Facility for connection of a
storey call button.
The telephone is also fitted with 6
buttons and 2 LEDs as permanent
features. The 2 LEDs can be assigned
any op-tional function, for example
display of front door or garage door
status. The LEDs are triggered via
12 V AC with a common reference
point „La“.
The 6 buttons can be used in con-
junction with a switching/remote
controller SFC 602-... to trigger
relays etc. or in conjunction with
Group Controller GC 612-... as
internal call buttons. If the HTC is
connected to the GC 612-..., bridge
"Br. 1" at the top right must be
disconnected.
Buttons 5 and 6 can be used as floa-
ting buttons if the perforated edges
at the bottom left and right are
broken off. Should you ever wish to
return these for use as call buttons,
for instance, the 4 bridges indicated
below must be soldered in.
