Hardwired Interconnected Smoke Detector - 5 Pack, Fast Alerts

Our review of this hardwired interconnected smoke detector pack finds it best suited for homeowners who want a straightforward, reliable home fire warning system. The main reason to buy is the interconnected design: when one alarm senses smoke, all units sound, improving the chance everyone in a multi-room house will wake or escape. Installation requires hardwiring but the included DC 9V backup batteries and a 10-year product life make this a low-maintenance choice for long-term protection.

Key Features

• Interconnected alarms: Up to 12 units can be wired together so a single detection triggers all alarms for whole-house notification.
• Backup battery: Each detector includes a DC 9V battery to keep the alarm functioning during a power outage and signals when battery replacement is needed.
• Photoelectric sensing: Enhanced sensing technology responds quickly to smoldering fires and reduces false alarms often caused by cooking.
• Do Not Disturb mode: A hold of the test button enables an approximate ten-hour Do Not Disturb mode to prevent nuisance alerts and flashing overnight.
• Test and LED status: Weekly testing is simplified with one test button that checks all interconnected units and LED indicators show normal and alert states.

Who It's For

This product is aimed at families and homeowners who want a coordinated fire alarm system across several rooms or floors and who are comfortable with hardwired installation or hiring an electrician. The pack of five suits medium to larger homes where multiple devices are needed to meet coverage recommendations.

It is not ideal for renters who cannot modify wiring or for people who need a plug-in or battery-only alarm with wireless app connectivity. If you require networked smart-home features or remote alerts, consider a different alarm with those integrations.
