TECHNICAL CHARACTERISTICS OF POWER SUPPLY ART. 6837/C17
Power supply in grey ABS housing; preset for mounting on cases with 12-module DIN support
- 117V A.C. 60Hz supply
- 30VA maximum absorbed power.
- Interchangeable cards for quick maintenance.
- Removable terminal blocks.
- Door lock output: 15V rectified D.C. 1A intermittent cycle (30 sec ON, 150 sec OFF), 0.25A continuous duty for push-button illumination (3x24V 3W max)
PROTECTIONS ON POWER SUPPLY:
- Primary coil of transformer: PTC SIEMENS Type C-840.
- Secondary coil for lock supply: PTC SIEMENS Type C945
- Internal electronic protection and protection of interphone audio line: PTC SIEMENS Type C-945.
Dimensions Art. 6837: 208x185x72 Weight: 1,3 Kg
In the event of a short-circuit, the protection circuit removes the mains voltage until the fault is rectified. After eliminating the short-circuit, it is
necessary to wait for a few minutes to allow cooling of the protective device, so that the power supply may start normal operation again.
OPERATING PRINCIPLE OF INSTALLATION WITHOUT CONVERSATION PRIVACY USING INTERPHONES ART. 8877 - 900/137 -
6201.
When the push-button corresponding to the user required is pressed on the entrance panel, the chime of the called interphone is activated,
called will sound. All the interphones are always in communication with the outdoor unit without conversation privacy, and the electric lock may
be operated at any moment.
OPERATING PRINCIPLE OF INSTALLATION WITH CONVERSATION PRIVACY, USING INTERPHONES ART. 0875/837 - 8873 -
0900/837 - (6201 + 7155).
Press the push-button corresponding to the user’s number on the entrance panel: the interphone chime is activated and an electronic memory system
activates the interphone. At the same time, any previously activated interphone is automatically excluded.
When the called user lifts the interphone handset, he or she can communicate with the outside in complete privacy.
The interphone is excluded when the door-opening push-button is pressed.
N.B.
Power supply Art. 6837 can produce two electronic notes: the first (P1) is normally used for calls from outside; the second (P2) may be used by con-
necting a push-button outside the apartment door and presetting an extra wire on interphone cable riser (see version 1).
With Art. 0900/837 the lock can be activated even if the interphone has not been called from outside. To do this, move the wire from position AC to position
AS.
To reduce the intensity of caall in Arts. 0900/837, transfer wire, on the printed circuit board, from connector 6A to connector 6B.
Disconnect jumper “A” on interphone Art. 6201 and connect card Art. 7155. Function settings for card Art. 7155:
- Direct door lock release in any istant: insert the wire in connector “SD”.
- Door lock release after call: insert the wire in connector “SR” .
