Hardwired Smoke Alarms

How often should I replace my smoke alarms?

It's generally recommended that smoke alarms be replaced every ten years. Depending on their location and upkeep, smoke alarms can wear out over time. If you're unsure when a smoke alarm was installed or if you believe it's close to approaching its ten year end of life cycle, you should replace it immediately.

Where should I install smoke alarms?

Early detection of smoke, carbon monoxide, and natural gas is key to saving lives. The National Fire Protection Association (NFPA) recommends the following placement:

• Every Level: Install a smoke alarm on every level of your home, including finished attics and basements.
• Sleeping Areas: Install a smoke detector inside every bedroom or areas where people may sleep.
• Stairways: Position alarms at the top of certain stairways to ensure rising smoke is detected quickly.

Do I need four kinds of detectors or can one do it all?

You never know what kind of hazard will strike your home, or when. That's why we recommend technology that can detect carbon monoxide (CO) and natural gas as well as smoke and fire. You'll get the most protection from detectors that can quickly and accurately respond to a range of threats.

What are “nuisance alarms”? Why are they a concern?

A smoke alarm that goes off when there's no emergency is annoying and often causes homeowners to intentionally disable their detectors. According to the NFPA, almost two-thirds of home fire deaths resulted from fires in homes with no working smoke alarms, often because units were deactivated due to false triggers.

Why does my smoke alarm "chirp" approximately once every minute?

A chirp indicates a "low battery" condition. AC powered smoke alarms with battery backup will chirp indefinitely assuming AC power is present until a fresh battery is installed. Certain models with a silence button may chirp for 8 minutes while in silence mode before returning to normal operation.

What is the total number of smoke alarms or devices I can interconnect?

The total maximum is twenty-four devices. Following NFPA 72 standards:

• Alarms: Up to 12 smoke alarms and up to 6 other alarms, such as heat or carbon monoxide alarms, for a total of 18 alarms.
• Accessories: With 18 alarms, you may add up to 6 additional relay modules.
• CAUTION: USI alarms should only be interconnected with other USI devices to prevent failure or nuisance alarms.
• Circuitry: All interconnected alarms should be powered by the same fuse or circuit breaker and should not be on a GFCI protected circuit.

Why should I go with hardwired smoke alarms?

Hardwired detectors provide a robust, integrated security solution for your home:

• Preexisting Integration: Easily plug into your home's preexisting wiring system.
• Battery Backup: Optimal protection that continues to operate even during a power outage.
• Interconnectivity: Link detectors to create a unified defense system throughout the entire property.
• Modern Standards: Options include Sensing Plus multi-criteria detectors that conform to UL 217 8th Edition.
