The USI Electric MCN108 Hardwired Carbon Monoxide and Natural Gas Smart Alarm is a 2-in-1 device that provides double the protection with a single installation. This dual-sensing alarm protects against two deadly household threats: carbon monoxide and natural gas (or methane). Perfect for new or replacement installations, the 120-volt AC/DC hardwired alarm is suitable for houses, apartments and mobile homes. Auto sensitivity calibration provides superior nuisance alarm protection and creates consistency in alarm sensitivity. This alarm has additional automatic features including a self-diagnostics check to ensure proper operation, a sensitivity adjustment for changes in temperature or humidity and an end-of-service life warning that sounds when it's time to replace the battery. The 9-volt alkaline battery (included) continues protection in the event of a power outage.

This alarm features a quick activation pull-tab and a front-loading battery drawer for replacement without removing the alarm from the bracket. Mount the bracket to any standard wiring junction box and use the large mounting base to cover imperfections in drywall. The plastic dust cover protects the alarm from debris and (2) tamper-resistant locks prevent unwanted alarm or battery removal. For maximum protection, install an alarm inside every bedroom, outside every sleeping area and on all levels of the dwelling. The USI Electric MCN108 Hardwired Carbon Monoxide and Natural Gas Smart Alarm comes with a 7 year limited warranty.

I ordered this model to replace an existing CO detector. Easy removal of two screws made this a simple change out. The existing harness plug worked as advertised. 5 minutes start to finish install. Great

I ordered replacement units directly from USI as the older ones, while still functional, were dated 2003. I called to place order, was treated well, and the products were well priced and shipped timely and free. I recommend this company!

Does Not Fit Well - 02/06/2018
Reviewer: Charlene Mason
We purchased this model MCN108 because we were told it was the correct replacement for an older model CD-9385. However, even with changing to the new universal bracket, we found that the alarm does not fit as snugly against the ceiling as the old model did.

Reviewer: Arne Hawkins
We built a new home and the builder installed Universal products. After 7 years both stopped working so I got on Amazon and ordered two replacements. Not long after, one stopped working and when I checked the manufacturing date, it was 5 years old already. Order direct from Universal and avoid additional costs!

This item was installed with great ease due to the compatible nature of the product. The CO detector is more current compared to the old, expired version obtained 7.5 years ago. We also ordered the smoke detectors and look forward to ensuring the safety of our family. Shipment was in a timely fashion.

Q: WHAT LEVELS (PPM) OF CARBON MONOXIDE CAUSE AN ALARM?

A: Carbon monoxide alarms are designed to alarm before the average healthy adult feels symptoms. Since you cannot see or smell CO, never assume it's not present. Underwriters Laboratories Inc. Standard UL2034 requires residential CO alarms to sound when exposure times and exposure levels of CO in the chart below. CO alarm levels are measured in parts per million (ppm) of CO over time (in minutes). The UL2034 Required Alarm Points are:

If the Alarm is exposed to 400 ppm of CO, it must alarm between 4 and 15 minutes.
If the Alarm is exposed to 150 ppm of CO, it must alarm between 10 and 50 minutes.
If the Alarm is exposed to 70 ppm of CO, it must alarm between 60 and 240 minutes.

Q: IS CARBON MONOXIDE HEAVIER THAN AIR?

A: Carbon monoxide is not heavier than air. A carbon monoxide alarm should be installed in a location where the alarm will stay clean, and out of the way of children or pets. Refer to the user's manual for specific installation requirements.

Q: WHERE SHOULD I INSTALL MY CARBON MONOXIDE ALARMS?

A: It is very important to install a carbon monoxide alarm outside each separate sleeping area, and for maximum protection, install one in every bedroom. Many states now require installation of a carbon monoxide alarm inside each bedroom. For added protection, placement of an additional carbon monoxide alarm at least 15-20 feet away from the furnace or fuel burning heat sources is recommended. Install carbon monoxide alarms a minimum of 10 feet from sources of humidity like bathrooms and showers. In multiple-story dwellings, install one carbon monoxide alarm on every level. If you have a basement, install a carbon monoxide alarm at the top of the basement stairs, and in each separate sleeping area.

Q: WHAT AREAS SHOULD I AVOID INSTALLATION OF A CARBON MONOXIDE ALARM?

A: Do not install carbon monoxide alarms in garages, kitchens, furnace rooms, or in any extremely dusty, dirty, humid, or greasy areas. Do not install alarms in direct sunlight, or areas subjected to temperature extremes. These areas include unconditioned crawl spaces, unfinished attics, un-insulated or poorly insulated ceilings, and porches. Carbon monoxide alarms should not be installed in outlets covered by curtains, heavy furniture or other obstructions. Do not install in turbulent air-near ceiling fans, heat vents, air conditioners, fresh air returns, or open windows. Blowing air may prevent carbon monoxide from reaching the CO sensors.
