Goodnight from Spain.
I would need to make a contact without electric charge (dry contact?) to connect the alarm. It is very simple: if the two cables are together, the alarm will be connected, if the two cables are separated, the alarm will be disconnected. I would like to know if it is possible to carry out this operation with the "4ch pro" (it is the one that seems more suitable to me) or with "1 Channel Inching / Self-Locking WiFi Wireless Switch 5V 12V"
Greetings and thanks!!
I'm sorry. Maybe I did not know how to explain. I have TWO CABLES coming from the alarm center. By joining these two cables (when making the connection) the alarm is switched on. If I disconnect them, the alarm goes off. What I need is a contactor, free of electric charge, that makes that on / off = Electrical connection but without electrical charge. I think that's called dry connect. The alarm is connected to a central office where they call me in case there is an incident. That is not a problem.
