How do I configure a MIMO2+ in Indigo for dry contact impute

I wired up my MIMO2+ to my alarm system to get dry contact inputs. How do I configure the MIMO2+ to do this in Indigo?

Thanks!
Rick

Rick, not sure what you are trying to do so hard to answer your question. Are you trying to close the MIMO relay and have indigo notice or are you trying to have indigo close the relay and have your alarm system notice?

Re: How do I configure a MIMO2+ in Indigo for dry contact im

I had the alarm company install dry contact relays for the various alarm statuses. I want to use the MIMO to detect when one of these contacts closes. The is no voltage, only the closing of the contact. I don't see a way to configure the device in Indigo to detect a dry contact closed.

Thanks for getting back to me.

Re: How do I configure a MIMO2+ in Indigo for dry contact im

Hi Rick, just trying to help you but FYI, I don't have one of these - did a quick read of the documentation (which leaves much to be desired in my mind). Here is something that I would try.

There are two signal inputs on the MIMO2+. SIG1 (Input 1) and SIG2 (Input 2), depending on the circuit design a signal input (usually) will float high if it is not given some path to ground. (I did not see mention of this in the documentation but I do have a 40 year HW background and I have seen this happen on most circuits). See second picture.

So, if you have dry contacts set up coming from you alarm system you should have four wires, (two from each relay). If you take a set of two wires (from one relay) and connect one to a MIMO signal input and the other to the MIMO ground (next to that signal input) when the alarm relay is open you should not have a path to ground and that signal connection should float high, when the alarm relay is closed a path to ground is created and the signal connection input should drop to zero volts. That should create an event Indigo can see. BTW, There is a utility that can be run to adjust the threshold points the signal inputs reacts to. I looked quickly at that document and it did not specify the default values, so you may need to get into that to tweak it to work with the float values. See first picture.

Same for the other input. This assumes your dry contacts are Normally Open but it could work either way. I don't have anyway to test this and if that does not work you might have to engineer in a voltage to detect.

Let me know if that helps, happy to stick with you if you would like - maybe someone else on the board has an identical setup and can provide some first hand info for you.

Diagrams below -- good luck!

What Norm said for the wiring, then check to see if Binary Input 1 and 2 device states change.

If not, then copy/paste the Event Log results after you force the inputs to change a few times into a reply. If nothing shows, then turn on Indigo's Z-Wave debug logging checkbox.

Thankyou Norm! I wired the contact switches as described. Indigo does not show any responses. I guess a big question is how do I configure the device in Indigo to sense dry contact closures.

Re: How do I configure a MIMO2+ in Indigo for dry contact im

I don't have the device but from what Matt said it looks like when you added it -- it should have created a master device and some sub devices - two of which represent Binary Input 1 and 2. When the alarm relay contact changes from open to closed those devices should change state (within Indigo). Those would be the items you trigger on to accomplish whatever you want to do. If they do not change state then you need to figure out what is happening .

If you have a multimeter step one would be to read the voltage on the high side of each Binary Input (the SIGNAL posts) when the contacts are open. They should read some voltage, when each relay in the alarm system closes that voltage should go to ground (drop to zero). If that is happening and you do not see a change at the indigo device then the threshold values may need to be adjusted.

If you do not see any devices for the signal inputs something may not be configured correctly or the device did not get added correctly to the z-wave network. Wish I had one so I could do some screen shots for you....

Ok,

I got it working..... I had to use the analog inputs and set the threshold voltages. I'm now a happy camper.
