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.
