Basic System Operation

Call sequence
When the call button is pressed at the entrance panel the apartment station will ring and
its blue pickup / view lamp will flash, highlighting the pickup and view symbols. The
apartment station will continue to ring for up to 30 seconds or until the resident responds
by touching the view symbol (see silent viewing below) or the pickup symbol. After using
the pickup symbol the resident can freely converse with the visitor whose image is now
displayed on the apartment station; at the same time the green lock symbol will flash to
highlight the lock function.
The call may be terminated by touching the pickup symbol again or more usually by
touching the lock symbol first to allow the visitor access through the entrance; the speech
and picture will persist for a further 3 seconds while the door is being released.
Silent viewing
When the apartment station is ringing the resident can touch the view symbol to answer
the call instead of the pickup symbol; this will stop the apartment station ringing and
enable them to view the visitor for up to 60 seconds or until the lock symbol is touched to
release the door. Silent viewing can be 'normalised' at any time by touching the pickup
symbol and conversing with the visitor as described above.
Apartment Station Controls
The diagram in the introduction shows the apartment station and its controls. The controls
are adjusted by touching the end of the slider and sliding the finger up and down. The
default setting is ringer volume halfway and contrast slider fully down.
Auto Display
When 'Auto Display' mode is selected the picture will come on while the apartment station
is ringing, otherwise the picture will only come on when the call is answered. Auto Display
mode is usually pre-selected at installation and generally only one apartment station per
flat should be set in this mode (see 'Extension Apartment Stations' below).
Ringer Mute
The resident can mute the ringing sound in the apartment station when they do not wish to
be disturbed. Ringer mute is activated by touching the mute symbol on the apartment
station, which then illuminates in red as a reminder. Touching the mute symbol a second
time will disengage the mute function. Ringer Mute only stops the audible ring, but the
blue ring lamp will still flash and all other functions work normally. Ringer mute will
continue for the pre-set time even if a call is answered.
During installation it is possible to set a time limit for the mute function in various values
from 2 minutes up to 10 hours or indefinitely. When this time period has elapsed the mute
function will automatically disengage. Default timeout is never (See 'mute timer', page 26).
Door Status Indication
The green lock lamp on the apartment station will illuminate to warn the resident that a
door has been left open following a call. This feature requires a door monitor contact to be
fitted.
