March 31, 2022CO Alarm
The process of purchasing the new CO Alarm was fine. I did though like the old model CO5120PDBN, with the digital display better than looking up what the beep sequence is indicating.

Ordered carbon dioxide detector from First alert store. They processed and sent the detector without delay. Called with mailing concern and they quickly and efficiently helped. A great Co. to work with and product is exactly what I needed. The web site is great. Thank You First Alert!

I buy all my smoke and CO alarms here. Prices are very good and my house is protected now, top to bottom.
Here are a few situations that may cause a carbon monoxide alarm "false alarm:"
- The carbon monoxide alarm needs to be relocated. Carbon monoxide alarms should be located 15-20 feet away from all fossil fuel burning sources like furnaces and stoves. Alarms should be located 10 feet away from sources of humidity like showers.
- Fossil fuel burning appliances may not be burning fuel completely. Check pilot lights/flames for blue color. Appearance of yellow or orange flames indicates incomplete combustion-a source of carbon monoxide.
Hardwired Carbon Monoxide Alarm with Battery Backup
This First Alert Hardwired Carbon Monoxide Alarm includes a battery backup that is perfect for meeting codes wherever CO detectors are required for new construction. The hardwired detector features a quick plug-in power connector that makes the installation process a near effortless one as it will connect right into your building’s wiring. Additional features such as a microprocessor that limits nuisance alarms and a single test/silence button add versatility to an already efficient carbon monoxide alarm.
Electrochemical Sensor Monitors CO Levels
The alarm features an advanced electrochemical sensor that detects carbon monoxide leaks from a variety of sources, such as faulty fuel-burning appliances, blocked chimneys, and cars left running in the garage. Carbon monoxide can't be seen, smelled, or tasted in the air, and it is the leading cause of accidental poisoning deaths in America. By placing carbon monoxide detectors on every floor of the home and in each sleeping room, you can help protect your family from the danger of carbon monoxide.
Battery Backup for Detection During a Power Outage
This carbon monoxide alarm is designed for hardwired installation, but it also features a battery backup that helps ensure continued functionality in the event of a power outage. The unit comes with a 9-volt battery and features a pivoting, easy-to-access battery drawer that allows you to replace the battery without dismounting the alarm.
Works in Tandem with Other First Alert Alarms
In addition to functioning independently, this carbon monoxide detector can also integrate with up to 12 other First Alert or BRK hardwired alarms for coverage of larger spaces. It also integrates with up to six other compatible devices, such as bells, horns, and repeaters. If one alarm in the series is triggered, they will all sound. The alarm features a latching indicator to identify which unit triggered the alarm, alerting you to the area of danger.
