TECHNICAL FEATURES OF POWER SUPPLIER ART. 6450
Power supplier for all two-channel hands-free audio door entry systems with "SOUND SYSTEM" call facility.
It is a new power supplier for intercom systems equipped with an electronic double tone generator which replaces conventional
alternative calling with a buzzer or bell. The sound is emitted with two different tones thereby allowing the user to immediately
identify the source of the call (main entrance, gate, garage, etc.). This feature provides economic and practical advantages
since the use of several conventional sound emitting systems is no longer required; the signal is emitted from a single loud-
speaker in the handset.
The power supplier can be used on installations without conversation privacy.
- 230V A.C. 50Hz supply (other voltages on request)
- 60VA maximum absorbed power.
- 18V D.C. 0.8A monitor supply.
- 13V D.C. 0.3A camera supply.
- 15V rectified voltage 0.25A continuous duty for push- button illumination (3x24V 3W max)
- 15V A.C.door lock output: 1A intermittent service.
- Amplified electric door-opener system.
- Interchangeable cards for quick maintenance.
- Removable terminal blocks.
N.B. This particular type of installation requires the use of the GALILEO series door entry panels with speech units Art.
930A. The use of this type of speech unit allows the microphone to be put away from the loudspeaker, allowing so a
balanced adjustment on the audio.
PROTECTION OF POWER SUPPLY:
- Primary coil of transformer by PTC SIEMENS C850
- 1st. secondary coil for internal electronic supply by PTC SIEMENS C965
- 2nd. secondary coil for lock supply by PTC SIEMENS C945
- Electronic protection against overloadings to outdoor unit.
ADJUSTMENTS
P2 - Volume adjustment of speech unit.
P3 - Activation time adjustment for electric lock.
N.B.: The electric door lock must operate by way of an intermittent cycle so that one
operating period corresponds to 5 rest periods, thereby preventing the protection
device from overheating (one period corresponds to the door lock activation time).
Dimensions Art. 6450: 208x135x72 - Weight: 1.4 Kgs.
OPERATION
The audio door entry installation consists of one entrance panel with speech unit, one power supplier and one or more
interphones. When an entrance panel push-button is pressed, the chime rings in the corresponding apartment. To communicate
with the outdoor unit, the user must press the button market until the end of the conversation.
If desired, the user may activate the door-opener; in this case the door opening time may be varied from 1 to 30 seconds using
the potemtiometer P3.
When testing the installed system, use trimmer P2 to adjust the optimal volume of the speech unit.
The power supplier is also equipped with a specific device to eliminate any buzzing on the voice circuit caused by the use of
wires that are too long and/or too thin.
Push-buttons with name-tags are illuminated through output 0-15 on power supplier. Up to a maximum number of 24V 3W
bulbs can be connected. An additional transformer, Art. M832 or 832/030 is required for entrance panels with more than three
bulbs. Intercommunicating networks cannot be created.
Interphones to be used on these installations are Art. 7400.
