sensors and open ame sensors be deployed. At least two sensors of each
type should be deployed, and the automatic re alarm system should be
enabled.
● The battery room should be equipped with independent air conditioners and
ventilation ducts, which must be isolated from those for other equipment
areas or oce areas. If air conditioners and ventilation ducts are shared, re
dampers must be installed for the battery room. The ventilation and exhaust
system must interact with the re alarm system and be able to handle
ammable gases with a concentration lower than 25% lower ammability
limit (LFL).
● The battery room should be equipped with a halogenatedane or
peruorohexanone gas re extinguishing system, which should interwork with
the re alarm system. After the extinguishing agent is released, the battery
room should meet the requirement on ame extinguishing concentration
within 10 min.
● The battery room should be equipped with re extinguishing facilities such as
a water spray (recommended) or water sprinkler system. Ensure that the
water stored can be supplied for more than 2 hours at the designed water
ow rate and the surrounding water source should be able to supply water
continuously for 12 hours to cope with the risk of reignition or re spreading
after a battery re is extinguished.
● The battery room should be equipped with pressure relief explosion-proof
devices or pressure relief channels (such as glass windows and magnetic lock
doors) with equivalent areas. According to the NFPA 68 or GB 50016
standard, if side pressure relief is adopted, a protective fence or wall should
be installed outside the pressure relief channels, and the fence or wall should
be at least 12 m away from the pressure relief wall.
● The battery room should be equipped with drainage facilities for the water
re extinguishing system.
● The battery room should provide coordinated control for re protection to
disconnect the power supply not intended for re protection in the area on
re and related areas. It is recommended that the power supply be
disconnected before the automatic sprinkler system is triggered.
● Fire alarms in the battery room should be automatically reported to the re
supervision center. If the battery room is unattended, an automatic re alarm
system should be deployed to report re alarm signals to the remote
management center.
