I used a volt meter to check the terminals and there’s just no voltage coming out of the AUX -/+ and the ALARM post (when it’s toggled on, of course). I escalated to support and they sent me a replacement, but this one also doesn’t have any voltage either! The non-alarm version has 12v coming out of AUX.
It’s configured in Home Assistant just fine. The switches to the windows toggle the status, everything seems to work. From Home Assistant I can turn on the siren and I see the light toggle on the device according to the siren on/off. I also used the web interface to toggle the siren, still no 12v coming out of those terminals.
And like I said, I have the non-siren 6 sensor version which just has a non-togglable AUX 12v and that measures fine with my multimeter.
Here’s an image I took a while back while I was setting it all up to give to send to a friend. The red arrow is the one not working.
It’s literally impossible for the AUX +/- to not have power of the barrel jack is powered – they are electrically connected to each other, nothing besides copper traces between these two connections.
Make sure that you are opening the “mouth” of the terminal block by twisting the screw counter-clockwise. If you insert the wire above the contact, it will not work.
I figured it out. I was testing the voltage through the terminal tops, which is normally fine. Once I screwed the multimeter leads in, I saw the voltage registering. I unscrewed the leads and tested the top again. Working! So, I unscrewed the terminals as much as possible, still working!
I then went back to testing the replacement board, which also didn’t register any voltage. I verified that there was no voltage coming out of the terminal tops. I simply screwed them down a little bit and back up and suddenly I was getting voltage. Well I got 10v. So I did it again, screwing them all the way down and back up and now I have 12v on that too.
I wonder if there was some sort of oxidation on the terminal metal that was preventing a connection, and exercising the terminals cleared it up. I never screwed them down all the way because the alarm I previously tested was really thick wire, so I barely screwed them down. That little movement must not have been enough to clear the oxidation.
Thank you for pushing me down a different troubleshooting path.
Can I mail you back the replacement board I was sent by support (I’ll pay shipping, no problem)? I would rather you have it for inventory and can resell it, as a way to support you guys. I really appreciate the support you guys have; I chose this board because of Home Assistant support.
Lol, I kinda guessed that was the case. Not the first time this has happened. Those black terminals work a little differently, the screw top is not electrically connected to the terminal. Also the “mouth” of the terminal closes from the bottom up, not top down like the smaller blue terminals.
Yes you can mail back the unneeded board to the return address on the shipping label. Thanks!
