2018 Update

Although nearly a year old, all of the information in this article is still relevant. It can be important to know how to replace a hard wired smoke detector; scroll down to find out how. 


Aside from the obvious benefit of never hearing the irritating and constant ‘chirping’ sound warning of a low or faulty battery, a hard-wired smoke detector provides a greater level of safety for your family.  A dead battery puts you at risk, while smoke detectors powered by electricity with battery backup will fulfill home safety and fire regulations. Another benefit is the ability of hard-wired smoke detectors to interface with or be linked into your monitored home security system. Monitored smoke detectors not only sound an alarm, but they will also contact the fire department. A quick response to household or business fires will save lives and property.

Continuous home monitoring by a professional security firm is one way to calm a parent’s mind for the safety of the entire family.  A Huffington Post study found the following statistics (numbers which can be quite alarming):

Although there is no doubt that smoke alarms help to save lives, a study has shown that domestic smoke alarms fail to wake up 80% of sleeping children. Research is increasingly showing that children, and particularly boys, are not disturbed by the sound.

Keep in mind that like all mechanical and electrical home products, they have a certain life-cycle and may fail eventually. The Consumer Reports Agency states that smoke detectors should be fully replaced after 10 years. The sensors will start to lose their sensitivity, putting your home at risk.

How To Replace A Hard Wired Smoke Detector

  • Shut off the power to that circuit at the main electrical panel
  • Unscrew the old detector from it ceiling or wall mount
  • Take note of the three wires are you detach them from the old smoke detector
  • Black=120V Power, White=Neutral, and Red or Yellow are the interconnecting circuit wires
  • If the wires are contained within a plastic plug, detach the plug
  • Remove the old mounting plate and any wire harness connected to your home wiring
  • Install the new wire harness by matching the connections to the black, white, and red house wires
  • Be sure to twist the metal wires to make a good connection and secure with electrical tape or wire caps
  • NOTE: for two-wire detectors – connect the black to black, and white to white
  • Screw the new mounting plate in place and bring the newly attached wiring harness out
  • Attach the new smoke detector plug to its receptacle from the wall/ceiling
  • Install the backup batteries in the new smoke detector head and screw onto base
