Wired Alarm. Are there smart WIRED sensors available? Or just Konnected?

[geotrouvetout67]

If your system has a relay or if you can add one, you can just add a z-wave dry sensor that will connect to ST. It won’t allow you to control anything but you can trigger things. See my post below (as well as the wiring correction I added right below), different alarm but same principle.

If you need to add a relay, a power source and the ZW097 sensor, you are looking at less than $100 for a light integration in ST. If you already have a relay with a free switch (ELK 924 are commonly used with alarm systems and have 2 switches) just connect the ZW097 to the NO and COM connectors.

GE Interlogix SIMON 3, XT, XTi integration

I did not try it yet but I think there is a simple way to integrate the Simon to ST as I am looking for doing the same thing. Simon alarm panels have ports for external sirens: HW1 I/O provides the negative and HW 1/2 OUT is the positive. When an external siren is installed, HW I/O is connected to the neg port of a relay such as the ELK924 commonly used and the HW 1/2 OUT goes to the positive trigger port of the relay. Using the same principle, you could use a Smartthings compatible door sensor and connect it to the relay switch port. I think a door sensor is normally closed so you would use the N/C and COM ports of the relay. Break the glass of the reed switch on the door sensor and solder wires from the switch contacts to the N/C and COM ports of the relay, or unsolder the reed switc…
