tend to require at least 1.5A peak current and this will require the use of an isolation relay
and a separate power supply for the lock.
Exit Button Input
The exit button is used to unlock the door for the preset lock operating time. The input is
designed only for use with a normally open push button. ‘Exit +’ is the input and ‘Exit –’ is
internally connected to 0V.
The ‘Exit +’ input can also be used for connection to other equipment to open the door as
shown in Diagram J – bellissimo Combined System Connections.
Door Open Switch
The door open switch is used to provide an indication at the phone that the door has been
left open. This switch can have closed contacts when the door is closed or open contacts
when the door is closed, the choice being made in Panel Programming. The default of
‘contacts open when door closed’ must be selected when this feature is not required.
Time Clock Sharing
In a large system a single time clock can be shared between distributed equipment areas
by borrowing one of the ‘comm -’ wires in the interconnecting Cat5 to use as the shared
“Time clock common”. See the detailed diagram on page 35.
Commissioning
The major components of the bellissimo Video system are fitted with high quality
pluggable screw terminal blocks. This enables all the connections to the system to be fully
completed, whilst easily isolating individual pieces of equipment during testing and
commissioning.
When powering up for the first time, it is highly recommended that only the most basic
system be connected. i.e. 1 BS videophone, 1 door controller and panel, and 1 video
controller; the remaining equipment can be isolated by unplugging terminal blocks.
NB: Ensure the 1 door and video controller remain interconnected and that the ‘end of line’
controller is terminated temporarily using the jumpers (see page 20).
Proceed to test the system by calling the videophone from the door panel in the usual way.
Any problems can be resolved by rechecking wiring and connections, assisted by the
various suggestions and tests in the section “Troubleshooting”. Once the basic system is
fully functioning, continue to reconnect and test the remaining equipment item by item until
completed.
