Wiring for a New Smoke Detector
Electrical Question: How should I wire a new smoke detector to the existing smoke detectors?
My electrical wiring project involves Adding to the Wiring for a New Smoke Detector in the Attached Garage of a Old Home.
- I have a 35 year old home that was completely redone 5 years ago. The contractors installed a wired/linked smoke detector system according to local building codes at that time. The home is a ranch style and is very long. One end is the attached garage and the opposite end is the bedroom section. There is approximately 70 feet of living space between the two areas. I want to add a smoke detector in the garage since fires often start there and there is no detector located there. If a fire started in the garage, it would take a long time for the detectors in the house to begin alarming. Anyway, if I want to add a detector, should I just tap into one of the existing detectors and run a single 14/3 wire to the new detector? Or do I have to do some kind of loop with the new detector wire? Thank you for your help.

Installing a smoke detector in the garage is a smart idea, just be sure to keep it clean and keep insects and spiders away to prevent false alarms in the middle of the night.
Add Wiring for a New Smoke Detector
Yes Spenser, just tap into one of the existing smoke detectors and run a single 14/3 wire to the new smoke detector location. Most wired smoke detectors with battery backup are fully compatible where the wiring connections are made color to color. The red wire is typically the alarm signal wire.
