Product Description

USI AMIC3511SB - 3-in-1 Hallway Smart Alarm with Sensing Plus Multi-Criteria Detection and 10-Year Lithium-Free Sealed Battery

The USI AMIC3511SB is a professional-grade 3-in-1 Smart Alarm engineered specifically for hallway installations, protecting against smoke, fire, and carbon monoxide threats with a single battery-operated unit requiring no hardwiring. Powered by Universal Security Instruments' patented Sensing Plus Multi-Criteria Detection Technology, this alarm combines an ionization smoke chamber with an electrochemical carbon monoxide sensor to deliver accurate protection against fast-flaming fires, slow-smoldering fires, and silent CO threats while virtually eliminating nuisance alarms from non-hazardous sources such as everyday cooking smoke and shower steam. The Permanent Power 10-year lithium-free alkaline sealed battery provides a decade of continuous protection with no battery changes required - and eliminates low-battery chirps for the full service life of the alarm. The lithium-free chemistry (Duracell Duralock Power Preserve Technology) is a safer, greener alternative to lithium-based 10-year alarms. Interconnection capability links this alarm to compatible USI devices throughout the home for synchronized whole-house warning when one alarm sounds. Quick-Find Alarm Origination identifies which alarm triggered the event, saving critical response time. Meets the new UL 217 8th Edition requirements for polyurethane foam fire detection, resistance to false alarms from cooking, and immunity to high-voltage current surges. Ideal for retrofit installations, rental properties, and homes without hardwired alarm wiring where comprehensive protection is still required.

Top Features

  • 3-in-1 Combination Protection: Protects against smoke, fire, and carbon monoxide threats in a single alarm - combines ionization smoke chamber with electrochemical CO sensor for comprehensive home safety.
  • Sensing Plus Multi-Criteria Smart Alarm Technology: Virtually eliminates nuisance alarms from everyday cooking smoke and shower steam while accurately detecting real fires and silent CO threats.
  • 10-Year Lithium-Free Sealed Battery: Permanent Power Duracell Duralock Power Preserve Technology provides a decade of continuous protection with no battery changes required - safer, greener alternative to lithium.
  • No Hardwiring Required: Battery-only installation makes this alarm ideal for retrofit, rental properties, and homes without existing alarm wiring - mounts to ceiling or wall with included hardware.
  • UL 217 8th Edition Compliant: Meets the latest UL safety standards including polyurethane foam fire detection, false-alarm resistance from cooking, and high-voltage surge immunity.
