DESCRIPTION

Art. 4933 is a concentrator with 6 outputs which directs the amplified video

signal (following a call or self-ignition) only towards the riser branch involved in

the call.

In order for Art. 4933 to work properly, the interval for the user addresses

(Standard Mode) or zones (Top Mode) wired to that output must be

programmed for each riser output used in the system.

CAUTION! It is not possible to connect an identical user address or zone

address on more than one riser branch, nor can there be overlapping

intervals, even if these are only partial.

1. Lin Lin Bus line connection terminals.

2. Terminal block M3

L1 L1 riser branch output 1.

L2 L2 riser branch output 2.

L3 L3 riser branch output 3.

L4 L4 riser branch output 4.

L5 L5 riser branch output 5.

L6 L6 riser branch output 6.

3. Green indicator LEDs DL1, DL2, DL3, DL4, DL5, DL6 for the selected

branch output.

4. Terminal protection.

5. P1 Programming button.

6. Dip-switch S2: identifies the branch address (Standard Mode) or zone

address (Top Mode) to program.

7. Dip-switch S1:

•

selectors 1 to 6 in the programming phase identify the branch output

to program.

•

selectors 1 to 6 in normal operation define the amplification level

(OFF= normal; ON= high).

•

selector 7 (only used in the programming phase): identifies the

address set on Dip-switch S2 as the lower (OFF) or upper (ON) limit.

•

selector 8 (only used in the programming phase for Top Mode):

identifies the zone addresses set on Dip-switch S2 (OFF=1-250;

ON=251-500).

8. JP1 jumper for accessing programming mode.

9A. DL8 yellow LED indicating (single flash) programming acquired.

9B. DL7 red LED indicating programming status:

•

lit steadily: not in programming mode and Art. 4933 with correctly

programmed addresses.

•

slow flashing: in programming mode and awaiting selection of

branch output to program.

•

rapid flashing: in programming mode and awaiting selection of

Standard or Top Mode, or with one of the 6 branch outputs selected

and awaiting range code entry.

•

ultra-rapid flashing: error or programming incompatibility, or in

delete mode.
