What are the connections and fault finding tips for a 1039/34 IPerVoice Decoder?


The 1039/34 Riser Decoder is the connection point to integrate the Apartment monitors into the IPerVoice Riser, 4 apartments can be connected into each decoder and by the selection of the apartment monitor DIP switch it is assigned to the appropriate decoder output.

For connection into the riser there are 2xRJ45 connections these are labelled Bus In and Bus Out these need to be connected into the riser with the 1039/50 side of the riser to Bus In.

There is 4 x Floor Call connection these are for the connection for the apartment Bell Push these will trigger the apartment monitor to complete 1 ring cycle. These must be connected in association with the correct apartment for example DER1 output = FC1 Floor Call Input.

Connection A2 in/out these are for the connection of the second Audio Channel which will allow a second Audio only call within the riser.
