This fast and accurate CO and smoke detector identifies threats early, giving you time to act and keep home and family safe.
Your home and family are safer with a detector that uses photoelectric sensors to identify excessive heat before you even smell smoke.
A built-in wireless transmitter communicates directly with your Smart Hub and Vivint app, alerting first responders if necessary.
This detector works with your Vivint smart home to shut down your HVAC system in the event of fire to mitigate the spread of flames.
The battery-operated combination CO and smoke detector comes with a 5-year battery plus backup, so it’s always on.
If your detector is triggered, our support team is notified instantly. They’ll contact first responders if you can’t be reached.

Absolutely. With a combination smoke and carbon monoxide detector you get double protection with a device that identifies life-threatening fire and CO. Technologies that work together to identify smoke and CO makes sense, given that carbon monoxide often builds up as a result of fire.
With a combination detector from Vivint you get the added protection that comes with 24/7 Monitoring. Our specialists are ready to respond to an alarm day or night whether you’re away or asleep in bed to ensure the safety of your home and family. See it and our other products in action.
Installing combination smoke and CO detectors is a simple way to streamline the interior of your home without sacrificing safety. Our combo detector is not hardwired, making installation easier. And fewer battery changes are necessary, and one unit requires less space than two separate units—convenient especially for smaller living spaces. Distinct alarms indicate whether smoke or CO is detected to avoid confusion.
Placement of your combination smoke and CO detectors is much the same as mounting individual detectors. And because the smoke CO detector is not hardwired, installation is easy. According to the National Fire Protection Association, you should install carbon monoxide and smoke alarms in the following spots:
On each level of a multilevel home
Near bedrooms and sleeping areas
Any other areas required by law
To make sure you’re protected again carbon monoxide, combination detectors should also be mounted in the following locations:
Near sources of CO.Place CO detectors 5-20 feet from common sources of carbon monoxide in the home, such as your water heater, furnace, or space heaters. Make sure you don’t place detectors too close to the sources, which could result in false alarms.
Near your attached garage. Running vehicles produce carbon monoxide through their exhaust systems. When a car is in motion or idling in an open space, carbon monoxide and other emissions dissipate and are released into the air as pollution. In enclosed spaces like a garage, however, the concentration of CO can quickly reach deadly levels and can seep into your home.
Try to place detectors approximately 6 inches above or below the ceiling. If ceiling mounted, the detector should be positioned at least 6 inches away from the wall. Other things to keep in mind:
Smoke and CO detectors should always be 5 to 15 feet away from fuel burning appliances.
Nothing should cover or obstruct the detector.
Avoid placing detectors next to exterior doors and windows.
Keep in mind that these are minimum requirements. Depending on the size of your home you may need additional detectors.
Choose Vivint for professional installation and round-the-clock-monitoring.
Protect your property with a camera that actively deters lurkers with light and sound and sends you notifications so you always know what's happening outside your home.
Unexpected visitors? With the Vivint Doorbell Camera Pro and smart locks as part of your system, answer the door with the Doorbell Camera, let visitors in your home with Smart Locks, and lock up when they leave.
Lock up with the press of a button or right form the Vivint app. With smart locks, you can set your system to arm when you lock the door, and know who's coming and going with unique access codes.

The install left a couple holes in the wall with ugly cords that I now have to deal with. This was not what I was told so it is going to be a repair issue now. Other than that the products are great, the coverage is great the hub works well, and the app does too. Much better than blink or ring.

We recently had Vivint Home Security installed in our home, and our experience has been wonderful! From the moment we first inquired, Lucas was our initial point of contact and made the entire process simple and seamless. He helped us choose the products we needed while staying within our budget, and we truly appreciated his guidance and professionalism. A special shoutout to Randy, who was extremely professional, knowledgeable, and genuinely helpful throughout the installation process. What I appreciated most was the time Randy took to answer all my questions, provide valuable insights into our current services, and walk me through additional security options we may want to consider in the future. It’s refreshing to work with people who take the time to educate you rather than simply sell you something. That level of care, patience, and professionalism makes all the difference! We’re excited to have this added layer of security and peace of mind for our family. Thank you, Lucas and Randy, for making our experience such a positive one! Highly recommend!
