Mich. Admin. Code R. 400.10527 - Fire detection; large facilities

Rule 527.

(1) A newly constructed, remodeled, or converted large facility that elects to provide fire protection through fire detection shall be equipped with a 100% coverage fire detection system which is tested and listed by a nationally recognized, independent testing laboratory and which is installed in compliance with the national fire protection association pamphlet no. 72A, entitled "Local Protective Signaling Systems," 1979, national fire protection association pamphlet no. 72E, entitled "Automatic Fire Detectors," 1978, and these rules, except that the installation of wiring and equipment shall comply with national fire protection association pamphlet no. 70, entitled "National Electrical Code," 1978.

(2) In a new, remodeled, or converted large facility, the main power supply source for an automatic fire detection system shall be from an electric utility company and shall be on a separate circuit which is fused ahead of the building main service switch. A secondary power supply shall be provided which, in the event of the main power supply failure, will maintain the system in an operative condition for 24 hours and, in the event of a fire, will sound the alarm signaling units at least a 5-minute period.

(3) In a new, remodeled, or converted large facility, where an automatic fire detection system is required, the detection devices shall comply with both of the following provisions:

(a) Be installed in all rooms, lofts, closets, stairways, corridors, basements, attics, and any other areas. Spacing of detection devices shall be as recommended by the manufacturer to provide complete coverage. Small bathrooms that contain a single water closet and lavatory, small closets that are not more than 20 square feet, and similar spaces are exempted from the provisions of this subdivision.

(b) Be smoke detectors, except that heat detectors may be installed in attics, kitchens, bathrooms, attached garages, and heating plant rooms instead of smoke detectors. Heat detectors shall be the fixed-temperature, rate-of-rise type.

(4) In a new, remodeled, or converted large facility, an automatic fire detection system shall be an electrical, closed circuit, self-supervised system which gives a distinctive signal in a staff-occupied area when trouble occurs in the system, including loss of the main power supply.

(5) In a new, remodeled, or converted large facility, complete final plans and specifications of the automatic fire detection system, where such a system is to be installed, shall be submitted to the department and approved before installation. The plan shall show facility floor plans and locations and types of detection devices, pull stations, and sounding units.

(6) In existing large facilities, fire detection systems that are approved before these rules take effect shall continue to be approved until the facility is converted or a portion thereof is remodeled. When the facility is converted or a portion thereof is remodeled, the portion of the facility remodeled or converted shall meet the appropriate requirements of this rule. Where the required new system cannot be added to the existing systems maintaining a single signaling alarm system, the total system shall be replaced and shall comply with this rule for remodeled and converted facilities.

(7) Automatic fire detection systems, fire alarm systems, and fire detection systems shall be maintained in proper working condition. When problems occur, they shall be immediately remedied. When the system is rendered inoperable, staff shall be awake and on duty until the system is again operable.
