Universal Security Instruments Sensing Plus Multi Criteria Hallway Smoke and Carbon Monoxide Alarm With 10 Year Tamper Proof Battery (AMICH3511SC)

The USI AMICH3511SC 3-in-1 Sensing Plus^® Smoke, Fire & Carbon Monoxide Alarm 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 combination 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, Universal Sensing Plus Alarms^® are suitable for houses, apartments and mobile homes in every room.

This 3-in-1 detector implements a 10 year lithium-free battery that 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.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. This combination detector features microprocessor intelligence that offers superior false alarm resistance. 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) have also been included.

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

This 10 year combination alarm conforms to UL 217 Standard 8th Edition and UL 2034 Standard 4th Edition. 8^th edition smoke, fire and carbon monoxide detectors have also been approved by the California State Fire Marshal and Federal Housing Authority (FHA) to exceed industry standards.
