6 Pack of USI Electric Hardwired 2-in-1 Carbon Monoxide and Natural Gas Smart Alarms with Battery Backup

Carbon Monoxide and Natural Gas Detection

The USI Electric MCN108 Hardwired Carbon Monoxide and Natural Gas Smart Alarm is a 2-in-1 device that provides double the protection with a single installation. This dual-sensing alarm protects against two deadly household threats: carbon monoxide and natural gas (or methane). Perfect for new or replacement installations, the 120-volt AC/DC hardwired alarm is suitable for houses, apartments and mobile homes.

Auto sensitivity calibration provides superior nuisance alarm protection and creates consistency in alarm sensitivity. This alarm has additional automatic features including a self-diagnostics check to ensure proper operation, a sensitivity adjustment for changes in temperature or humidity and an end-of-service life warning that sounds when it's time to replace the battery. The 9-volt alkaline battery (included) continues protection in the event of a power outage.

This carbon monoxide and natural gas alarm features a quick activation pull-tab and a front-loading battery drawer for replacement without removing the alarm from the bracket. Mount the bracket to any standard wiring junction box and use the large mounting base to cover imperfections in drywall. The plastic dust cover protects the alarm from debris and (2) tamper-resistant locks prevent unwanted alarm or battery removal.

For maximum protection, install an alarm inside every bedroom, outside every sleeping area and on all levels of the dwelling. The USI Electric MCN108 Hardwired Carbon Monoxide and Natural Gas Smart Alarm comes with a 7 year limited warranty.

Hardwired carbon monoxide (CO) and natural gas alarms are a sophisticated and highly effective solution for protecting your home from two of the most dangerous, yet invisible, household threats. Unlike single-purpose alarms, these dual-sensor units are permanently wired into your home's electrical system, providing a continuous power source for both carbon monoxide and natural gas detection. This hardwired connection ensures unwavering reliability, as the alarms are always on and actively monitoring for leaks. Many of these units are designed to be interconnected, so if one alarm detects a leak, all linked alarms throughout the house will sound off simultaneously, providing a prompt and widespread alert. To further enhance their dependability, these alarms are often equipped with a 10-year sealed battery backup. This vital failsafe guarantees that the alarm remains fully operational even during a power outage, ensuring your family is protected from dangerous gas leaks when they might be most vulnerable. This comprehensive, integrated approach provides a superior level of safety and peace of mind.

• Continuous, Uninterrupted Power: Wired directly into your home's electrical system, the alarm receives a stable power source 24/7. This eliminates the risk of the alarm being disabled due to a forgotten or dead battery.
• Early, Widespread Warning: Hardwired alarms can be interconnected. If one unit detects a gas leak, all connected alarms will sound simultaneously throughout the home, ensuring every resident gets an immediate, life-saving warning, regardless of their location.
• Meets Building Codes: Many modern building codes and regulations require hardwired and interconnected alarms for new construction and major renovations, making this a future-proof and code-compliant choice.
• Dual-Threat Protection: A single, integrated unit provides comprehensive protection against both odorless, toxic carbon monoxide and potentially explosive natural gas, simplifying your home safety setup.

• Reliable Failsafe: The battery backup ensures the alarm remains fully functional during power outages. This is crucial as power failures can often be associated with events that lead to gas leaks (e.g., storms, equipment failure).
• Convenience and Flexibility: Unlike sealed batteries, a removable battery allows you to replace it without having to replace the entire unit. This can be a more cost-effective option over the alarm's 10-year lifespan.
• Easy Maintenance: You have the ability to swap out the battery to address a low-battery chirp, extending the alarm's functional life until the full 10-year end-of-life replacement is needed.
• Immediate Operation: In a temporary power outage, the removable battery ensures the alarm is immediately ready to go, providing peace of mind when it's needed most.
