Mich. Admin. Code R. 400.4524 - Fire detection; large facilities
Rule 524.
(1) An
existing licensed large facility electing to provide fire protection by 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 standard No. 72, entitled "National Fire Alarm
Code", 2013 and these rules except that the installing of wiring and equipment
shall comply with national fire protection association standard No. 70,
entitled "National Electric Code," 2014 .
(2) In an existing licensed 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 with an
identified and locked circuit breaker . 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 for a 5-minute
period.
(3) In an existing licensed
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 areas; that is, all
rooms, lofts, closets, stairways, corridors, basements, attics, and like areas.
Spacing of detection devices shall be as recommended by the manufacturer to
provide complete coverage. Small bathrooms containing a single water closet and
lavatory, small closets which are not more than 20 square feet, and similar
spaces are exempted from this requirement.
(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 and shall be in compliance with NFPA 72.
(5) In a new, remodeled, or converted large
facility, complete final plans and specifications of the automatic fire
detection or alarm system, where such a system is to be installed, shall be
submitted to the department and approved prior to installation. The plan shall
show facility floor plans and locations and types of detection devices,
pull-stations, and sounding units. Newly required systems shall have a panel or
annunciator located in an area regularly occupied by staff.
(6) In large facilities, licensed prior to
November 30, 1983 , fire detection systems shall continue to
be approved until the facility is converted or a portion thereof is remodeled,
then 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
devices 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.
(8) Fire alarm systems shall be tested and
maintained on an annual basis in accordance with NFPA 72. Smoke detector
calibration shall be done as recommended. The licensee shall keep a record of
fire alarm maintenance.
