“V1O” and “V2O” to the terminals “V1L” and “V2L” (connected to the local camera), connecting the
block entrance with the user required (during the conversation all other users in that block will be busy
for the length of the “local call”.
- If the call arrives from a main entrance, the system leaves the “BUS” connections and the video outputs
(only 2206V) in stand-by mode and, for the length of the call, the users’ line of the main entrance will be
busy.
Programming
The programming of the 2206A-2206/V consists in the configuration of the internal 4 way Dip-switch to
indicate the number of intercoms connected to the output (Eg. A block with 37 intercoms connected: Dip-
switch 1/2/4=OFF, 3=ON). This programming is used to adjust the impedance of the system according to the
phones connected; a wrong configuration could cause feedback (“Larsen” effect). See the following table for
the correct programming.
Operation Notes
On long runs if the video signal deteriorates we recommend use the V2P and V1P outputs to the following
block which supplies a reconditioned video signal to the rest of the system.
