Call

To call an apartment press the relative push-button on the front door unit (Audio/video
module with 2 push-buttons GW 18 302 and 4 push-button module for front door unit
GW 18 321) or select the name or apartment number in the Call module with electronic
index for front door unit (GW 18 322).
When the call is made, the audio/video module will emit a brief tone to confirm it is
functioning properly; this tone can be disabled when configuring the device.
If the call is made using a push-button panel (audio/video module with 2 push-buttons or
4 push-button module), the red light located behind the name holder plate of the push-
button that was pressed will start to flash; when the called apartment answers, the red
light remains switched on during the entire conversation.
If the called apartment is already engaged in a communication with another front door
unit, the audio/video module will emit a busy signal.
For information about the call module with an electronic index, see the relevant user
manual.
If the Call exclusion function is active on the apartment unit, the name holder plate will
be illuminated fixed red, and if the call push-button is pressed a busy signal is obtained
(with call modules with an electronic index, the call exclusion is signalled by the message
"Do not disturb, thank you").
If there is no answer, and if the apartment unit has a video entryphone with an enabled
video entryphone answering machine function, a recorded voice will ask the caller to
leave a video message.

Electro-lock operation

The audio/video module for front door unit can manage two types of electro-locks:
• Standard, with impulse discharge: the electro-lock remains open until the door
is opened and reclosed by the user.
• With self-closure, where the electro-lock closes automatically once the time
set on the audio/video module DIP switches has passed. This operating mode
requires a maintenance current for the entire time the electro-lock must remain
open.
