NOTE: The entrance module and guard door switchboard
station must be configured for TYPE 1.
The entrance module may be programmed for
UNRESTRICTED DOOR LOCK RELEASE (step 5 = 0) or for
DOOR LOCK RELEASE PROTECTED BY PRIVACY
FEATURE (step 5 = 1).
NOTE: Power supply unit Ref. 826/25 can supply one
entrance module and a maximum of 20 decoders. Additional
power supply units must be installed if further decoders are
needed. In this case, power supply unit cond 24 must
UNDER NO CIRCUMSTANCES be connected together: each
must supply a separate group of four-port decoders (up to 30).
The guard door switchboard station must be supplied by
means of its own power supply unit.
INSTRUCTIONS: In Day service, guard door switchboard
station intercepts all calls from the video entrance module.
The switchboard attendant uses the station handset to
establish voice communication with the visitor, and the video
doorphone to view the visitor.
Apartment station video doorphones use the • key to call the
switchboard, and the XXX key to release electric door locks.
To disable call interception, connect entrance module terminal
+ 24 to switchboard station te24N instead of riser
cable power supply unit te24. Under these conditions,
calls from the entrance module will not cause the guard door
switchboard station to ring during Day service (entrance door
open at all times).
For systems of this kind, no video doorphone is installed at
the guard door station.
