The Universal Security Instruments MPC122S 2-in-1 Photoelectric Smoke and Carbon Monoxide Alarm provides 10 years of continuous protection against deadly threats in the home. The utilization of photoelectric technology allows for increased efficiency in detecting slow smoldering fires. This USI 2-in-1 alarm has also been equipped with a CO detector that's capable of sensing the presence of carbon monoxide in the surrounding area. Perfect for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes. The sealed battery (included) will never have to be replaced throughout the life of the alarm, giving you a decade's worth in peace of mind even in the event of a power outage.
Permanent Power also saves money from battery replacements (up to $38.00 over the 10-year life of the alarm), eliminates annoying low battery chirps and helps the environment by reducing environmental waste from disposed batteries. This 2-in-1 detector features smart alarm technology to assist in completely eliminating nuisance alarms, a single silence/test button to quiet a non-hazardous alarm and an end-of-service life warning that sounds when it's time to replace the battery (approximately 10-years from activation).
The perfect replacement for existing Universal Security Instruments Alarms, this detector features a large mounting base to cover imperfections in drywall and the option to replace retrofitting applications. The quick deactivation key switches the alarm off and makes the batteries safe for disposal. Once the alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.
This USI Combination Alarm exceeds industry standards by meeting new laws and legislation. The Universal Security Instruments MPC122S 2-in-1 Photoelectric Smoke and Carbon Monoxide Alarm is ETL listed to UL Standard UL 217 and UL2034. This USI Alarm is also California State Fire Marshal approved.

I replaced my existing smoke detectors with a smoke detector/CO detector combo unit. Installation was easy, fast and perfect. Highly recommended.

Who knows how good the product is until it's used! I replaced 5 smoke only units from this company after 10 years, these seem to be made with same quality.

I had to return one of the detectors I ordered. It was faulty. The return process was easy and the staff was very helpful. I received my new replacement device in one week, installed it and it operates fine. Thank you.
