![]() It is a general purpose regulated power supply with selectable 6, 12, or 24v DC output (defaults to 12v) and built in battery charger which can be found for around $24. I also needed to supply the new Arduino boards with 12v DC and if I use the existing wiring the tablet/phone with 5v DC. So I needed to find something that could not only charge the battery but convert the 16.5v AC over to 12v DC. Also some of my existing sensors such as smoke/heat, glass breakage, and siren need 12v DC also. ![]() However my battery is 12v DC and is charged off of the current alarm panel which I will be removing. First my current panel has a 16.5v AC power adapter which it turns out is pretty standard for security/alarm systems. So once I decided on the Konnected project I started to do some research on what else I would need. I wanted to maintain as much hardware as I could on the current system (door chime on my keypad, siren for alarms, hardwired sensors, etc).I wanted to replace my one keypad with a small Android based tablet or phone.I wanted battery backup for the replacement system.I wanted to remove it so I had room for the new stuff without it looking crappy. I didn’t want the old security board installed at all. ![]() A couple things that I wanted to accomplish: I plan on putting in a MRK1000 or Arduino for some other things but for this project I was willing to pay a little extra for simplicity. Switch or renew?) and I ended up deciding on the Konnected Security project ( ) simply because I wanted a “packaged” solution. I asked for some suggestions ( Guardian Security System up for renewal. This thread is to document the replacement of my current security system. Tl dr - Converted existing security system to SmartThings using the Konnected Security 2.0 product and some other stuff for around $165 and a full days work.
