OPERATION
When switched on for the first time (assigning ID of internal devices) the separator 949S allows the transit of 4- or 8-digit commands together with the voice lines
between internal and external in order to facilitate internal programming. Once all the internal IDs have been assigned, the separator or the various separators
inserted in the system must be programmed as the initial user and final user connected to them. Programmed in this way by sending a call which is within the
range (initial user - final user), the voice line relay of the separator is connected so as to allow the transit of both the call and the voice line towards the calling
panel. Note that the monitors equipped with an internal generator (series 6600) ring even if they are not within the range (initial user - final user) but as regards
the voice line they are not connected to the entrance panel. Once activated, the separator is reset either for another call or at the end of the call. The device
repeats all the digital commands that it receives from the two serial lines in the opposite serial line.

DESCRIPTION ART. 949S
Art. 949S is a separator accessory for use in DIGIBUS systems with both 4 and 8 digits to create:
• An electric protection on the power supply.
• A physical separation for the digital line (the commands are retransmitted) and the voice line (normally disconnected from the rest of the system) between
one group of interphones/monitors and the rest of the system.
Power supply: 13.5 VDC
Max. Absorbed Power: 0.5W
The separator is connected in the system between the entrance panel and the group of interphones/monitors to be “protected”. It is possible to install the sep-
arator art. 949S either on the wall or on a DIN rail. (see Fig.1).
This accessory is used only for internal devices with a decoder on board.
