Section 425 ILCS 10/2 - Installation requirements(a) Every facility shall be equipped with at least one approved smoke detector in an operating condition within 15 feet of every room used for sleeping purposes. The detector shall be installed on the ceiling and at least 6 inches from any wall, or on a wall located between 4 and 6 inches from the ceiling.(b) Every facility shall have at least one approved smoke detector installed on every story of the facility, including basements but not including unoccupied attics; provided that there shall be at least one detector at the beginning and at the end of each separate corridor or hallway 200 feet or more in length in any occupied story, including basements.(c) Every facility shall have at least one approved smoke detector at the uppermost ceiling of each interior stairwell, except in fire resistive structures. The detector shall be installed on the ceiling, at least 6 inches from the wall, or on a wall located between 4 and 6 inches from the ceiling.(d) The requirements of this Section shall apply to any facility in existence on July 1, 1988, beginning on that date. Except as provided in subsection (e), the smoke detectors required in such facilities may be either battery powered or wired into the structure's AC power line, and need not be interconnected.(e) In the case of any facility unit that is newly constructed, reconstructed or substantially remodelled after December 31, 1987, the requirements of this Section shall apply beginning on the first day of occupancy of the facility after such construction, reconstruction or substantial remodelling. The smoke detectors required in such facility shall be permanently wired into the structure's AC power line and, if more than one detector is required to be installed within the facility, the detectors shall be wired so that the actuation of one detector will actuate all the detectors in the facility unit. In the case of any facility unit that is newly constructed, reconstructed, or substantially remodeled on or after January 1, 2011, smoke detectors permanently wired into the structure's AC power line must also maintain an alternative back-up power source, which may be either a battery or batteries or an emergency generator.
(f) Compliance with an applicable federal, State or local law, rule or building code which requires the installation and maintenance of smoke detectors in a manner different from this Section, but providing a level of safety for occupants which is equal to or greater than that provided by this Section, shall be deemed to be compliance with this Section, and the requirements of such more stringent law shall govern over the requirements of this Section.(g) In the case of a facility subject to this Act, the provisions of this Act shall be enforced by the State agency which licenses that facility. The State licensing agency may suspend the facility's license for a violation of this Act where appropriate.Amended by P.A. 096-1292,§ 5, eff. 1/1/2011.
