securitywarehouse Posted February 16, 2011 Share Posted February 16, 2011 please could you help me with a wiring question. I have puchases a 3021a handset which replaces an old creeam coloured videx vx handset. The old handset had 5 connected points at 1,2,5,6 and 7. Before disconnecting I labelled the wires, removed the handset and re-connected at the same points but I have noticed there is no connection 7 on the 3021a model. The new model has connection points 4,6,2,1,3,5,9,8 but no point 7? So now I have an unconnected wire. Could you please provide some help on this.

accounts3 Posted March 3, 2011 Share Posted March 3, 2011 Use terminal 3 as both 7 & 3 are negative terminals Quote Link to comment Share on other sites More sharing options...
