Costco Smoke Detector & Carbon Monoxide Detector, 2 Pack by First Alert


Change Your Clock, Change Your Battery! I’m sure everybody has heard that saying 1 way or another as a reminder to change the battery on your smoke detector. Here we have a 2 pack of Costco smoke & carbon monoxide detectors (scroll for photos). These are great because it solves 2 problems with 1 device. The smoke detector will detect smoke & alert you if there is a fire; the carbon monoxide will alert you (with a different tone) of the deadly gas carbon monoxide. Carbon monoxide is produced when fuels such as gas, oil, coal and wood do not fully burn. It can be caused by a running car, faulty water heater, fireplace, gas stove, oven, generators, power tools, wood stoves, etc. These are now required in homes by California law. A brief google search shows the following (note: there may be updates to these laws so please check your local building code)…….

  • The California State Building Code requires that smoke alarms be located in 1) the hallway outside the bedrooms 2) in each bedroom and 3) on every floor regardless of whether there is a bedroom on that floor
  • Carbon Monoxide alarms must be installed outside each separate sleeping area in the immediate vicinity of the bedroom(s), and on every level of home, including basements.

Yes, these are a little pricier than the smoke detectors alone, but they are totally necessary. Carbon monoxide is the silent killer. There are too many stories of people falling asleep & not waking up. If you are unsure of how many you need, you can’t go wrong with installing extra. Here are a few details about this specific brand First Alert Smoke & Carbon Monoxide Alarm 2 pack…….

First Alert Smoke & Carbon Monoxide Detector


First alert has been around since 1958. They are a highly rated product & in homes all over the US. They even give you a graph on the back of the recommended placement of these alarms/detectors so you have a good idea where to start. 3 out of every 5 home fire deaths resulted from fires in homes with no working detectors. That is a very grim statistic for something that is so simple. Just do yourself a favor & grab these Costco Smoke Carbon Monoxide Detector’s.

Nest Smoke/Carbon Monoxide Alarm


Now if you’re looking for a “SMART” smoke/carbon monoxide detector. I highly recommend the NEST system. They have tons of cool features so you can remotely check your detectors even when you’re not home. I like the idea that when I’m not home I will be alerted if there is any smoke or carbon monoxide in the house. It’s a great insurance policy for me if I happen to leave something on the stove. They are a little pricier than the First Alert Smoke & Carbon Monoxide Detectors, but they are great & I highly recommend them. Please check them out here……..
