The smoke detectors are an important aspect of every home safety. With many smoke detectors in the market today, everyone is looking for an electrical system that provides unwavering protection. With all the confusion in the market, hardwired detectors emerge as the most reliable and consistent.
This guide will unravel the mystery behind hardwired smoke detectors, the installation process, and today’s top-notch models.
Picture a world where you never second-guess your home’s safety – that’s the promise of hardwired detectors. Curious? We thought so. Stay tuned as we dive into the details, answering questions about hardwired smoke detectors.
What Is a Hardwired Smoke Detector?
These are smoke detector connected to your home’s electrical wiring and do not rely on batteries. They always have power, even if the electricity goes out, as long as it has a backup battery. A hardwired smoke detector is interconnected in that if one detects smoke, all of them will sound an alarm, giving you more time to escape and prevent the fire from spreading.
These devices uses ionization, photoelectric, or dual-sensor sensors to detect smoke. The Ionization smoke detectors are more sensitive to flaming fires, while photoelectric smoke detectors are more sensitive to smoldering fires. Dual-sensor smoke detectors combine both types of sensors for better coverage.
How to Install Hardwired Smoke Detectors
Since installation of hardwired smoke detectors can be challenging, it is recommended that you hire a professional electrician. However, if you are confident in your DIY skills, you can follow these general steps to install hardwired smoke detectors:
- Turn off the power to the circuit you will work on at the main breaker panel.
- Choose the locations for your smoke detectors, following the manufacturer’s instructions and the local codes.
- Install at least one smoke detector on each level of your home. Avoid placing them near sources of steam, dust, or cooking fumes, as they can cause false alarms.
- Drill holes in the ceiling or wall where you will mount the smoke detectors, and run the electrical wires from the nearest junction box to each hole. Use a wire coat hanger to pull the wires through the holes.
- Connect the wires from the junction box to the wires from the smoke detector, following the color coding and the wiring diagram provided by the manufacturer.
- Connect the black wire to the black wire, the white wire to the white wire, and the red wire to the red wire.
- The red wire is used for interconnection to enable smoke detectors to communicate with each other.
- If your smoke detector has a CO detector, connect a yellow wire to a yellow wire. Use wire nuts to secure the connections, and wrap them with electrical tape for extra safety.
- Attach the mounting bracket to the ceiling or wall with screws, and snap the smoke detector onto the bracket.
- Install the backup battery in the smoke detector and test the device by pressing the test button. You should hear a loud beep from your home’s smoke detector and all the other interconnected smoke detectors. If not, check the wiring and the connections and try again.
- Restore the power to the circuit, and enjoy the peace of mind of having hardwired smoke detectors in your home.
