Interconnected Smoke & CO Detector Installation

Oregon's Interconnected Smoke Alarm Requirements: What Every Homeowner Must Know

Oregon has some of the most comprehensive residential fire safety requirements in the nation, and understanding these requirements is essential for every homeowner in Lane and Douglas Counties. Oregon Revised Statute 479.255 requires that all single-family homes and dwellings have smoke alarms installed in every sleeping room, outside each sleeping area, and on every level of the home including basements. For homes with fuel-burning appliances, fireplaces, or attached garages, carbon monoxide alarms are also required on every level and within 15 feet of each bedroom door. Critically, Oregon building codes require that all newly installed smoke alarms in homes with existing 120-volt wiring be hardwired and interconnected — meaning that when any single alarm detects smoke, every alarm in the home sounds simultaneously. This interconnection requirement is based on compelling fire safety research: studies by the National Fire Protection Association (NFPA) show that interconnected alarms provide up to 30 additional seconds of warning time compared to standalone alarms, which can make the critical difference between safe evacuation and tragedy. Checkpoint Electric LLC strictly follows all Oregon building codes and NFPA 72 installation standards, ensuring your home's alarm system provides the maximum possible protection for your family.
