MPC122S & MPC322S Recall Frequently Asked Questions

1. Why is Universal Security Instruments taking this action?

Universal Security Instruments, Inc., in cooperation with the U.S. Consumer Product Safety Commission, is recalling photoelectric combination smoke and carbon monoxide alarms manufactured in 2017. The alarms can fail to alert consumers to the presence of a hazardous level of carbon monoxide, posing a risk of carbon monoxide poisoning or death. Carbon monoxide (CO) is an odorless, colorless, poisonous gas.

2. How do you identify recalled units?

The cover of the alarm must say Photoelectric Smoke & Fire + Carbon Monoxide Alarm. If the alarm says Universal Security Instruments, Inc. on the cover it is battery powered. If the alarm says USI Electric on the cover it is an AC/DC model which requires the power to be turned off prior to removing from the bracket. After you turn off your AC power at the circuit breaker or fuse box, the green LED will now be off and then it is ok to remove the alarm from the bracket. If green LED is still on DO NOT remove from bracket. Contact USI immediately with any questions at 1-877-220-0046.

If you have a model with the correct markings on the cover remove the alarm from the mounting bracket by twisting it counter clockwise. The models covered by the recall are models MPC122S with a date code of 2017JUN02 and MPC322S with a date code of 2017JUN09. After checking your alarm, please reinstall and push the test button to make sure your unit is working properly.

3. If I have one of the recalled models?

You can go to our website https://www.universalsecurity.com/reg-form-2022/alert/ and follow the instructions. Or you can call 1-877-220-0046, or email safety@universalsecurity.com.

4. What do I do while waiting for a replacement?

If you have a recalled alarm, reinstall the alarm while waiting for a replacement.

5. What do I do after I receive my replacement?

Once you get the replacement, follow the installation instructions outlined in the product user’s manual. Be sure to test the alarm. Deface your recalled alarm with the word “RECALLED” on both the front and back of the alarm in permanent marker, send a photo of the defaced unit to USI at safety@universalsecurity.com, and then dispose of the recalled alarm in your household trash.
