All existing dry chemical and wet chemical extinguishing systems shall comply with UL 300, Fire Testing of Fire Extinguishing Systems for Protection of Restaurant Cooking Equipment.
- Carbon dioxide extinguishing systems (NFPA 12, Standard on Carbon Dioxide Extinguishing Systems).
- Automatic fire sprinkler systems (NFPA 13, Standard for the Installation of Sprinkler Systems).
Exceptions:
- Automatic fire-extinguishing equipment provided as part of listed recirculating systems in accordance with UL 710B. [NFPA 96:10.2.5]
- [DSA-SS and DSA-SS/CC] Public school kitchens, without deep-fat fryers, shall be upgraded to a UL 300, Fire Testing of Fire Extinguishing Systems for Protection of Restaurant Cooking Equipment, compliant system during state-funded modernization projects that are under the jurisdiction of the Division of the State Architect.
Penetrations and holes resulting
from the removal of conduit or piping shall be
sealed with listed or equivalent liquid-tight sealing
devices. [NFPA 96: 10.2.7.2]

nozzle(s) such as baffle plates, shelves, or a modification
shall not be permitted. [NFPA 96:10.2.7.3]
Changes or
modifications to the hazard after installation of the
fire-extinguishing systems shall result in re-evaluation
of the system design by a properly trained, qualified,
and certified person(s). [NFPA 96:10.2.7.4]
Grease removal devices, hood exhaust plenums, and
exhaust ducts requiring protection in accordance with
Section 513.1 shall be permitted to be protected by a
listed fixed baffle hood containing a constant or fire-actuated
water wash system that is listed and in accordance
with UL 300 or other equivalent standards and shall be
installed in accordance with the requirements of their listing.
[NFPA 96:10.2.8.1]
The water
for listed, fixed baffle hood assemblies shall be permitted
to be supplied from the domestic water supply
where the minimum water pressure and flow are
provided in accordance with the terms of the listing.
[NFPA 96:10.2.8.3]
The water supply shall
be controlled by a supervised water supply control
valve. [NFPA 96:10.2.8.4]
A water-wash
system approved to be used for protection of the
grease removal device(s), hood exhaust plenum(s),
exhaust duct(s), or combination thereof shall include
instruction and electrical interface for simultaneous
activation of the water-wash system from an automatic
fire-extinguishing system, where the automatic
fire-extinguishing system is used for cooking
equipment protection. [NFPA 96:10.2.8.6]
The water required for
listed automatic fire-extinguishing systems shall be
permitted to be supplied from the domestic water
supply where the minimum water pressure and flow
are provided in accordance with the terms of the listing.
The water supply shall be controlled by a supervised
water supply control valve. Where the water
supply is from a dedicated fire protection water supply
in a building with one or more fire sprinkler systems,
separate indicating control valves and drains
shall be provided and arranged so that the hood system
and sprinkler system are capable of being controlled
individually. [NFPA 96:10.2.9]
Valves controlling
the water supply to listed fixed baffle hood assemblies,
automatic fire-extinguishing systems, or both shall be
listed indicating type of valve and shall be supervised
open by one of the following methods:
- Central station, proprietary, or remote station alarm service.
- Local alarm service that will cause the sounding of an audible signal at a constantly attended point.
- Locking valves open.
- Sealing of valves and approved weekly recorded inspection. [NFPA 96:10.2.10]
