Partyline: Can I trigger a TW-47 / 2-way radio from a KB-702 panel connected to a MS-704 main station?
Question: We have a TW47 connected to Channel D on the MS-704. Can I add a pair of KB-702's and have them connected to channel A and D? If i do, is the switch located at the top middle of the faceplate what determines which channel they are monitoring (A or D)? Lastly, if they are on a Channel D and press the Call button, will that trigger the relay on the TW-47 just as it does on Channel D of the MS-704?
Answer: Yes the KB-702 is a two channel wall mount panel, the terminal strip on the back allows wiring to two different channels. Yes the rocker switch determines which channel is talking / listening to, you can talk / listen to only one channel at a time. Yes, if you are talking / listening on Ch D and trigger the call button you will activate the transmit mode on the 2-way radio connected to the TW-47.
