All hooked up and working!
Great, I’m glad it’s all working and its always satisfying to have it finished and working. I assume you’ve tested it using one of the with the Konnected zones. I’ve implemented a similar configuration on my smoke alarms. As a final stress test I’ve cut the 120vac power to the smoke alarm and depressed the test button yo see if the 9v backup battery in the alarm will trigger the Konnected zone and it does. So I have confidence that even in the event of a fire and the house power goes out the Konnected system will work. Which also means having a backup battery for your Konnected board and siren / strobe should be considered to complete the system.
Yep, I tested it, but my system only works with 120VAC. The alarms work on the 9V, but don’t activate the relay. While it would be good to have monitoring when the power is out, I’m happy to at least have it monitored the majority of the time.
I do have a UPS powering my modem/router, the ST hub and Konnected boards.
The next project will be the back up data connection, looking at the Netgear LB2120.
I reviewed the relay on the link you provided (https://www.amazon.com/gp/product/B0039PF21U/) and it requires 120 Volts AC to operate.
In my configuration I elected to use a 5 volt DC power and Ground pins on the Konnected board as the power source for a 5 volt DC relay rather then a 120 volt relay. Either will work it was just a matter of preference and I had a 5 volt DC relay avsilsble.
