I have an ST hub and contact sensor set up at work that notifies me of a fire alarm activation triggered when smoke curtains come down (contacts separate when curtain drops).
I have a second problem which I’m hoping someone can help me with. I have a communication system present in a room that is activated by a push button. The button is connected via an RJ11 cable with two contacts. When the button is pressed, the circuit is momentarily closed and the system is activated. I want to add a wireless switch to this system using ST. Is a relay the correct item to use and if so can anyone recommend something simple and cost effective? It just needs to join the two contacts for a moment. I’m not so good with electronics but I think I could successfully strip and RJ11 and wire the contacts into a relay with screws. Does the relay itself need to be powered some how and if so, with what? There’s power available in the room. Do they come with mains adaptors?
As a follow on, will any z-wave scene controller button be able to activavate my relay? Ideally I want a single button.
I want user to be able to push a single button which momentarily joins two low voltage contacts and activates my existing communication system.
I’d appreciate any advice.
