DESCRIPTION
Type 7214 is a 7200 series open-voice monitor with 7" TFT LCD screen
(thin film transistor for active matrix display) with 16:9 widescreen
aspect ratio, for DIGIBUS video interphone installations. It is equipped
with a backlit keypad consisting of 8 push-buttons, 4 for conventional
functions: door lock release, conversation, stair light service, and 4
push-buttons for activation of additional auxiliary functions. These latter
push-buttons are also used for the following settings: brightness and
contrast control, ringtone volume control and mute, selection of different
ringtones, conversation volume control, selection of communication
mode and activation of automatic answer function. The device also has
two LEDs (red and green) for indicating ringtone mute, door/gate open
and setting mode.
The monitor is equipped with a removable cover and is available in a
range of alternative colours. Installation of monitor type 7214 requires
the use of back box type 7249.
The back box is made of ABS plastic and is equipped with a cover to
prevent the ingress of mortar and grout during masonry work. Its dimen-
sions are 189x160x52 mm.
Caution: In the case of systems with separate cameras, we recommend
using cameras with a minimum resolution of 420 TV lines.
