How Many Zones Do I Need?

A good rule of thumb is that smaller homes usually require less coverage. But don’t worry, there’s an easy way to learn how many zones you need.

If your home has a pre-existing traditional alarm system, the zones are most likely listed by the keypad or inside of the alarm system box (the one with all the wires). Count them and voila - you’re ready to select the right Konnected panel!

Not sure how many zones you need for your new pre-wired home? The industry standard is grouping your windows together - each floor or cardinal direction is one zone. We also recommend that you keep each door and motion sensor as separate zones to ensure the most precise monitoring possible!

Looking to Replace Your Old Keypad?

You can upgrade the look and function of your home by replacing your old alarm system keypads with wall-mounted tablets after you've converted your wired alarm system. Wall-mounted Amazon Fire tablets are a beautiful and inexpensive way to create a DIY smart home dashboard.

Run power to the tablet using your alarm system's pre-existing keypad wiring and our 12V to 5V USB adapter and 3D printed tablet frames.

Prefer to keep the traditional keypads? Shop our Interface Kit that allows parallel connection with your existing system.

“My experience with the store & setting up the Konnected panel was really easy to accomplish! Plan to purchase more & add-on's!”

Fred K

"The instructions and videos guide you through the connections to the alarm panel, setting up the Konnected app, and then getting it into the SmartThings app. Worked right away out of the box."

Stuart H

"OMG, this piece of kit is outstanding and works seamlessly. It kinda pays for itself too because I've made some of my Smart Motion Sensors redundant and then sold them on eBay."

A zone in the context of alarm systems refers to a sensor or a group of sensors. Each zone in your system will show up in your smart home app as an individual device that you can name. For example, a single door sensor wired to a zone may be named "Front Door". You may also have a group of windows wired together on one zone and call it "Downstairs Windows". A good place to start is by looking at your existing alarm system and count the number of zones. Often the keypad from your old system will have a zone listing either handwritten on a label, or programmed into the display.

Conversion kits work as a replacement to your traditional alarm panel or an addition to your new-pre wired home. Interface kits allow you to keep the traditional alarm panel and add smart home functionality to it.

If you'd like to keep using your existing keypad, make sure to purchase one of our Interface Kits (instead of the Conversion Kit). Interface Kits allow you to keep the functionality of your traditional keypad, while adding the all-new smart home possibilities controlled from your phone, tablet or computer. If you want to stop using your keypad and monitor your home only with smart home platforms, choose any of the Conversion Kits. No matter your requirements, Konnected has a solution for you.

Great product, this is the future of alarms

Very easy to setup took less than 10 min. Competitively priced. Lots of zones compared to the competition. The home assistant integration is both robust and lightning fast. My sensors update in real time.

Superb addition to the the 21st century home!

This was exactly the product I was looking for. Thanks to Nate and the team for putting it all together, what a brilliant way to snaz up your old home alarm system! Power over ethernet worked fine for me and the board immediately powered on and subsequently was recognised in my home assistant instillation :) I had no trouble wiring up my existing wired door sensor and 5 motion sensors to the board as it has nice handy screw terminals for the wires, once again these appeared correctly in home assistant after configuring them. It was also a breeze to wire up the piezo buzzer so we still have a door open / close sound just like the old system using the existing wiring from the old keypad. Also, I had no trouble using home assistant's manual alarm panel configuration and setting the konnected board up for remote monitoring / notifications depending on what state the unit was in. Its all working exactly as I expected. *Just as random project, I wired up a simple push button doorbell button to one of the 12 output zones and that works great in home assistant too! so I managed to have a very cheap and simple configurable doorbell that I wasn't planning for but this board gave me an easy platform to do so :) The documentation is great for this unit from konnected's website which pretty much helped me do everything, thanks again! Overall I would score this unit an easy 10 out of 10 if your use case is the same as mine. 1. to upgrade old wired alarm system to 21st century 2. to combine with existing home assistant installation for remote monitoring Bonus 3. to pass the wife friendly test when I told her she would be able to disarm the alarm system with her phones NFC reader after setting up an NFC tag and/or that presence detection could do it automatically. Job done!

Worked out perfect for my smart home!

Extremely easy to wire and connect to the internet. I was able to easily connect to SmartThings (without hub) and then connect SmartThings to Google Home. My virtual switches in SmartThings show up in Google Home and enabled me to create routines. With routines in Google Home is was able to automate messages throughout all my smart speakers. Currently my house announces the following: Door Open, Alarm is disarmed, Armed Stay will be active in 20 seconds, Armed Away will be active in 20 seconds, Intruder Alert. Siren will sound in 20 seconds. I purchased 3 Fire 7 tablets to use as control panels and installed ActionTiles on them. The fire tablets display (Always on) time, date, 3 day weather, front door Nest camera, driveway Nest camera, garage open (with security code), arm stay, arm away, disarm (with security code).....and status of all door, window and motion sensors. Battery backup was installed in modem, router, all wifi points and Konnected alarm board. I did this all for less than half the price of the most affordable alarm company I could find and don't need to pay a monthly fee for their ineffective monitoring. I may add more smart switches to my panels for home control....still deciding since I can already control all the switches with voice commands. Added bonus is that I know how everything works if there are ever any issues in the future. Highly recommended!
