My issue is that I have a non monitored house alarm and I want to be able to get an alert when it goes off but also be able to disarm remotely.
When the alarm is triggered it closes a volt free contact in the alarm box and I was hoping that you have a module which is similar to a digital input when closed will send a message to the controller.
Also when the alarm goes off I want to be able to switch it off remotely. There is a contact in the alarm box when closed will reset the alarm. Do you know of a digital output module which will close a contact command. I believe the voltage at this pair of terminals is 5 volt DC.
Ideally a volt free switched contact switched by the controller
Hopefully you can help me with this problem.
