Current through Register Vol. 56, No. 18, September 16, 2024
(a)
Automatic Fire Sprinkler System: An automatic fire sprinkler system shall be
installed throughout all floors containing the Group A-2 nightclub and all
floors between the Group A-2 nightclub and the level of exit discharge when the
conditions in (a)1 or 2 below exist. For purposes of applying this section, the
level of exit discharge shall be defined as having all exits discharging not
more than five feet above nor more than two feet below the adjacent grade.
1. The work area is located on a floor other
than the level of exit discharge; or
2. The work area is at the level of exit
discharge and has an occupant load of 300 or more or a net occupiable floor
area of greater than 5,000 square feet.
3. The automatic fire sprinkler system shall
be tied to the performance sound system and to the house lights in such a way
that activation of the automatic sprinkler system mutes the performance sound
system and restores the intensity of illumination to that required by the
building subcode. (Fire)
(b) Automatic Alarm System: When the occupant
load of the work area exceeds 100, an automatic fire alarm system that complies
with NFPA 72 shall be installed throughout.
1. If the alarm is activated by smoke
detectors, it shall be activated by either two cross-zoned smoke detectors
within a single protected area or a single smoke detector monitored by an alarm
verification zone or an approved equivalent method and the smoke detectors
shall be of a type designed to reduce the possibility of false notifications
based on the conditions present in the area protected.
2. The automatic fire alarm system shall be
tied to the performance sound system and to the house lights in such a way that
activation of the fire detection system mutes the performance sound system and
restores the intensity of illumination to that required by Section 1008.2.1 of
the building subcode. (Fire)
(c) Manual alarm system: For buildings
greater than three stories in height with occupant loads over 25, when the work
area exceeds 25 percent of the gross enclosed floor area of the building, or
for buildings where the occupant load of the work area exceeds 100, manual fire
alarms shall be required throughout the building. (Fire)
(d) Vertical Opening Protection: When the
work area exceeds 50 percent of the gross enclosed floor area of the building,
vertical opening protection shall be provided throughout the building as
follows:
1. A minimum two hour fire rated
assembly with approved opening protectives shall be required for interior
stairways and other vertical openings connecting more than six floor
levels.
2. A minimum one hour fire
rated assembly with approved opening protectives shall be required for interior
stairways and other vertical openings connecting four to six floor
levels.
3. A minimum 30 minute UFC
fire barrier shall be required for interior stairways and other vertical
openings not exceeding three stories. Exceptions shall be permitted as follows:
i. When connecting the main floor and
mezzanines; or
ii. When all of the
following conditions are met:
(1) The
communicating area has a low hazard occupancy or has a moderate hazard
occupancy which is protected throughout by an automatic fire suppression
system;
(2) The lowest or next to
the lowest level is a street floor;
(3) The entire area is open and unobstructed
in a manner such that it may be assumed that a fire in any part of the
interconnected spaces will be readily obvious to all of the
occupants;
(4) Exit capacity is
sufficient to provide egress simultaneously for all the occupants of all levels
by considering all areas to be a single floor area for the determination of
required exit capacity; and
(5)
Each floor level, considered separately, has at least one-half of its
individual required exit capacity provided by an exit or exits leading directly
out of that level without having to traverse another communicating floor level
or be exposed to the smoke or fire spreading from another communicating floor
level. (Plan review--Building, Fire. Inspection-- Building)
(e)
Requirements for high-rise buildings: Any building or structure having one or
more floors used for human occupancy located either more than six stories or
more than 75 feet above the lowest level accessible to a fire department
vehicle, shall comply with the following:
1.
When the work area is one entire floor or more or when the work area is 20
percent or more of the occupied floor area served by a recirculating air
system, the recirculating air system which serves the work area shall be
equipped with approved smoke and heat detection devices installed in accordance
with the UCC. The devices shall stop the fan(s) automatically and shall be of
the manual reset type. Automatic fan shutdown is not required when the system
is part of an approved smoke removal or smoke control system.
(Building)
2. When the work area is
one entire floor or more or when the work area is 20 percent or more of the
occupied floor area of the building, all elevators in the building shall be
equipped with the following emergency control devices:
i. All automatic (nondesignated attendant)
elevators having a travel distance of 25 feet or more above or below the
designated level shall be equipped with Phase 1 Emergency Recall Operation as
required by ASME A17.1-1987, Rules 211.3a and 211.3b listed in N.J.A.C.
5:70-3;
ii. At least one elevator
shall be equipped with Phase II Emergency In-Car Operation, as required by ASME
A17.1-1987, Rule 211.3c; and
(1) In buildings
with multiple elevators, at least one elevator to each floor served by an
elevator shall be equipped with Phase II Emergency In-Car Operation.
iii. All designated attendant
elevators having a travel distance of 25 feet or more above or below the
designated level shall be equipped with emergency controls, as required by ASME
A17.1-1987, Rule 211.4. (Elevator)
3. When the work area is one entire floor or
more or when the work area is 20 percent or more of the occupied floor area of
the building, standpipes shall be provided up to and including the highest
floor that is part of the work area. The standpipes shall be located and
installed in accordance with the building subcode, except as follows:
i. No pump shall be required provided that
the standpipes are capable of accepting delivery by fire department apparatus
of a minimum of 250 gpm at 65 psi to the topmost floor in buildings equipped
throughout with an automatic fire suppression system or a minimum of 500 gpm at
65 psi to the topmost floor in all other buildings. (Where the standpipe
terminates below the topmost floor, the standpipe shall be designed to meet
these requirements (gpm/psi) for possible future extension of the
standpipe.)
ii. Hose and hose
cabinets shall not be required. (Fire)
(f) Elevator Devices: When the work area
exceeds 50 percent of the gross enclosed floor area of the building, all
elevator devices serving any part of the work area shall comply with the
requirements of
5:23-6.30(g).
