Connection of a CCTV monitor
Attention! Please use a monitor with no earth connection (Class II) or
use a ground loop separator. CCTV monitor can work either in continuous
or timed mode. In the case of continuous mode (direct powering from
the main) monitor is still powered-ON also when the door station is not
connected (no image).
In timed mode monitor is powered-ON only when the door station is in
connection (with image). To operate in this way it is necessary to
connect the CCTV monitor as shown in the following diagram and
program the internal relay of doorkeeper exchanger as reported in the
chapter “Operating mode of internal relay” (see page 4.34).
