IL HB0051

Amends the Smoke Detector Act to modify battery requirements for battery-powered smoke detectors in existing dwelling units, requiring self-contained, non-removable long-term batteries instead of standard replaceable batteries.

Battery requirement changes apply only to battery-powered detectors that are over 10 years old, fail operability tests, malfunction, or are newly installed.

Exempts certain devices from battery requirements including centrally monitored alarm systems, wireless devices using low-power radio frequency or Wi-Fi capability with early warning notifications, and devices designated by the State Fire Marshal.

Repeals prior exemption that excluded dwelling units and hotels in municipalities with populations over 1,000,000 inhabitants from smoke detector requirements.

Hotels remain responsible for installing and maintaining smoke detecting equipment and providing specialized detectors for deaf and hearing impaired guests at a rate of one per 75 occupancy units (maximum 5 per hotel).
