Questions about smoke & co detector wiring.
For new installations and many remodels, current building codes require interconnected detectors so that when one sounds, they all do. We install to that standard.
Near any fuel-burning appliance — furnaces, water heaters, fireplaces — and outside each sleeping area. We position them to current code as part of the quote.
Yes. Upgrading older battery-only detectors to interconnected, hardwired units with battery backup is one of our most common jobs on older homes.
Yes — every unit we install includes battery backup so the detector functions during a power outage.
Detector wiring as part of a larger project typically follows that project's permit. We'll tell you whether a separate permit applies and handle it where needed.
