Mulligan Posted May 3, 2019 Share Posted May 3, 2019 We have 3 audio amplifiers and wanted to use the 12v trigger to turn them on and off when one of the 6 zones are used in each amp. # 1 - Is it best to use Relay or Contact? # 2 - The amps are not added to the rack. Would 3 fake amps need to be added # 3 - If we used 3 relays or contacts, will they each only turn when a room assigned to that amp is used?

lippavisual Posted May 3, 2019 Share Posted May 3, 2019 #1- if wiring from the controller, you would be using 12v from the contact and a relay to control the flow. 2- yes, it would be easier to add a driver in composer so the system knows what amps are attached to what rooms and when to control it. 3- see #1 and 2, yes alanchow 1 Quote Link to comment Share on other sites More sharing options...

When testing the plug I am getting 12V for all conditions. Am I not reading this diagram correctly? I have added the correct CONTACT and RELAY to the correct AMP and room assignment but curious as to why I am getting the constant 12V vs when only the room is selected on or off. Thanks for the clarifications. Quote Link to comment Share on other sites More sharing options...

If I get a 3 wire 3.5mm plug, do I then just put the tip in CONTACT +12V and the other two in RELAY: COM and RELAY: NO? I found this online and thought it might be an easy solution? No. Voltage flows overs 2 wires, 12V triggers are 2 wire (TS) connectors. Then on the Control4 side, it feeds through a relay to open and shut the voltage.

Mulligan Posted May 20, 2019 Author Share Posted May 20, 2019 Thank you. I updated my post since you replied. This is what I am using now with the two wire. Still just getting constant 12V. know it must be a simple solution, im just not finding the correct combination I guess. Quote Link to comment Share on other sites More sharing options...
brucecampbell Posted May 20, 2019 Share Posted May 20, 2019 I think you might want to use NO as opposed to the NC NC is normally closed - therefore the circuit is connected by default - providing you with your 12 volts until something opens the circuit.

thegreatheed Posted May 20, 2019 Share Posted May 20, 2019 NC = normally closed. So, until the relay is open, it'll be closed and give you 12V. Quote Link to comment Share on other sites More sharing options...
brucecampbell Posted May 20, 2019 Share Posted May 20, 2019 I'm assuming you will also need a trigger built in to your project either by adding a relay to the room and programming it to open/close based on room selections. or there may be drivers which do this already??

I added a phantom Control4 108 amp and bound it to the room and the relay and contacts Quote Link to comment Share on other sites More sharing options...
Mulligan Posted May 20, 2019 Author Share Posted May 20, 2019 This is how it is now wired This is how it is now programmed. Still no joy. Oh well, I will let you know what I finally figure out incase anyone else needs a pictorial for dummies like I do. Thanks for the help.
