VIDEO SWITCH & DECODER D2FD
DECODER PART WIRING
Wiring
① Tens digit: At tens digit area, the short-circuit number is effective numbers; address is the summation of the
effective numbers.
② Units digit: At units digit area, the short-circuit number is effective numbers; address is the summation of the
effective numbers. Address of decoder is consisted with the units digit and tens digit.
③ Connect indoor phone: If audio system two cores are non-polarity. If video system L+ and L- corresponding the
video phones.
④ Connect with main wire “V” “T” “G” to corresponding on door station.
Example: A staircase with seven (7) storey’s and five (5) apartments per floor; connection of flat four (4) on the
floor seven (7). The apartment number is zero-thirty-eight (037).
① Jumpering = 1 + 2 = 3
②Jumpering = 1+2+4 = 7
