POWER SUPPLY Art. 6680/C17 FOR SINGLE AND
MULTI-RESIDENTIAL VIDEO DOOR ENTRY SYSTEM WITH
STANDARD 15V A.C. CALL
N.B.:
FOR THE CHARACTERISTICS OF THE POWER SUPPLIER, REFER TO THE
DESCRIPTION ON THE POWER SUPPLIER FOR SINGLE AND MULTI-FAMILY
VIDEO DOOR ENTRY SYSTEMS WITH “SOUND SYSTEM” CALL FUNCTION.
OPERATION:
The power supply with the “A-B” selector set at “B” does not take account of the note generator located internally and therefore makes the
call to the monitor via terminal 15 (15V ac). Each monitor has its own AC bell, and in this way it differs from previous models. In this ope-
rating mode the power supply Type 6680/C17 completely substitutes Type 6580.
For the other characteristics and adjustments please follow steps laid out on page 3, of power supplier with “SOUND SYSTEM” call.
