The Smart Home Alarms device can accept 6V to 24V DC in the base, or 5V DC via USB cable directly to the logic board. If you’re replacing an existing alarm panel system, you can probably draw 12V DC from the existing system. Many alarm systems also have back-up batteries that you can take advantage of in this case.
Powering the Device from an Existing Alarm Panel
Most traditional alarm panels output 12V DC power from two screw terminals labeled AUX Output. This is used to power your home’s motion sensors, keypad, glass-break sensors, etc. You can tap into this power output to power your Smart Home Alarms device. Use your alarm panel’s wiring diagram or user’s manual to identify the 12V DC AUX Output terminals.Below are some examples of some popular alarm panel wiring diagrams highlighted with what to look for:

Step by Step Instructions
1. Disconnect the Power to the alarm panel before you begin. Usually this means unplugging a power adapter and unplugging the backup battery.
2. Find the AUX Power Output on your existing alarm panel. It should be two screw terminals labeled with AUX+ or + and COM, - or G. There are probably already a number of wires attached to these terminals for your various powered sensors and keypad. Loosen the screw terminals with a screwdriver, being careful not to let any existing wires slip out.
DO NOT CONNECT THE KONNECTED DEVICE TO AC POWER. Do not confuse the AUX Power Out on the alarm panel with where the alarm panel receives AC power. Connecting the device to AC power will damage the device and may result in electrocution or fire!
3. Verify that the AUX Power Output is between 6V and 24V DC. Usually the voltage is labeled on the wiring diagram or user’s manual. If not, verify with a multimeter.
4. Using the DC Power Pigtail insert the red bare wire into the AUX + (or +) and tighten. Insert the black bare wire into the COM (or - or G) and tighten.
