Universal Security Instruments Sensing Plus Multi Criteria Smoke, Fire and Carbon Monoxide Alarm With 10 Year Tamper Proof Sealed Battery (AMIC3511SB)

The USI AMIC3511SB 3-in-1 Sensing Plus^® Smoke, Fire & Carbon Monoxide Detector provides 10 years of continuous protection against deadly threats in the home. New Sensing Plus^® Multi-Criteria Detection provides the benefits of both photoelectric and ionization alarms in one device to protect against fast flaming and slow smoldering fires. This USI Electric Smoke and Carbon Monoxide Detector also offers protection against the silent killer - carbon monoxide - making it a 3-in-1 alarm. The ideal addition for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes in every room.

This 3-in-1 smart alarm utilizes a sealed battery (included) that will never have to be replaced throughout the life of the detector, giving you a decade's worth in peace of mind even in the event of a power outage. 10 Year 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. Thi USI electric combo detector features microprocessor intelligence that assists 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).

Perfect for replacing existing USI Alarms, this combination detector features a large mounting base to cover imperfections in drywall and the option to replace retrofitting applications. The quick activation battery pull tab makes it easy to install while the deactivation key switches the alarm off and makes the batteries safe for disposal. Once the 3-in-1 combination alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.

This USI Electric Smoke and Carbon Monoxide Detector conforms to UL 217 Standard 8th Edition and UL 2034 Standard 4th Edition.
