The following terms are defined in Chapter 2:
- BATTERY SYSTEM, STATIONARY STORAGE.
- CAPACITOR ARRAY.
- CAPACITOR ENERGY STORAGE SYSTEM.
- CRITICAL CIRCUIT.
- EMERGENCY POWER SYSTEM.
- ENERGY MANAGEMENT SYSTEMS.
- FUEL CELL POWER SYSTEM, STATIONARY.
- STANDBY POWER SYSTEM.
- STATIONARY BATTERY ARRAY.
Required critical circuits shall be protected using one of the following methods:
Emergency power systems, including all appurtenant components, shall be inspected and tested under load in accordance with NFPA 110, NFPA 70, and NFPA 111.
Exception: Where the emergency power system is used for standby power or peak load shaving, such use shall be recorded and shall be allowed to be substituted for scheduled testing of the generator set, provided that appropriate records are maintained.
Routine maintenance, inspection and operational testing shall be overseen by a properly instructed individual.
Roof access, pathways, and spacing requirements shall be maintained in accordance with the applicable building code. Pathways shall remain capable of supporting the loads required by the applicable building code. Pathways shall be maintained unobstructed and free from vent pipes, conduit or mechanical equipment unless otherwise approved in accordance with the applicable building code.
Exception: Where it is determined by the fire code official that the roof configuration is similar to that of a Group R-3 occupancy, the residential access and ventilation requirements in Sections 1184.108.40.206 through 1220.127.116.11 are a suitable alternative.
There shall be a minimum 6-foot-wide (1829 mm) clear perimeter around the edges of the roof.
Exception: Where either axis of the building is 250 feet (76 200 mm) or less, the clear perimeter around the edges of the roof shall be permitted to be reduced to a minimum width of 4 feet (1219 mm).
Interior pathways shall be provided between array sections to meet the following requirements:
A rapid shutdown switch shall have a label located not greater than 3 feet (914 mm) from the switch that states the following:
RAPID SHUTDOWN SWITCH FOR SOLAR PV SYSTEM
Stationary storage battery systems having capacities exceeding the values indicated in the applicable building code or technologies not listed therein shall be approved by the building official. Stationary storage battery systems shall be maintained in accordance with the applicable building code.
Exception: The fire code official is authorized to approve smaller separation distances if large scale fire and fault condition testing conducted or witnessed and reported by an approved testing laboratory is provided showing that a fire involving the system will not adversely impact occupant egress from adjacent buildings, or adversely impact adjacent stored materials or structures.
Fire areas within buildings containing stationary storage battery systems exceeding the maximum allowable quantities indicated in the applicable building code, shall comply with the applicable building code requirements for Group H occupancies. Where a maximum allowable quantity is not listed in the applicable building code, quantities must be approved by the building official.
MAXIMUM ALLOWABLE BATTERY QUANTITIES Deleted
Where cabinets contain storage batteries and are located in occupied spaces required by the applicable building code to be provided with ventilation, the ventilation shall be operated and maintained. Where supervision of ventilation systems is provided or required by the applicable building code, it shall be maintained.
Exception: Capacitors regulated by NFPA 70, Chapter 460, and capacitors included as a component part of other listed electrical equipment are not required to comply with this section.
Exception: The fire code official is authorized to approve lesser separation distances if large-scale fire and fault condition testing conducted or witnessed and reported by an approved testing laboratory is provided showing that a fire involving the system will not adversely impact occupant egress from adjacent buildings, or adversely impact adjacent stored materials or structures.
