Auxiliary Systems in
Data Centers
Auxiliary Systems are critical components in data centers to ensure the safety
of personnel and equipment. They are designed to quickly detect and respond
to potential fire hazards, minimizing damage and providing prompt alerts for
proactive measures.

Fire Hazard & Its Impact
Potential Hazards
Studies reveals that 43% of businesses that closed due to fire never reopen and
29% of those that do reopen fail within 3 years. With these statistics in mind, it is
imperative that all businesses prepare themselves for unseen disasters. The good
news is that the most effective method of fire protection is fire prevention
2 NFPA
The NFPA is responsible for creating fire protection standards, one of them being
NFPA 75. NFPA 75 is the Standard for protection of computer or data processing
equipment. One notable addition to NFPA 75 that took place in 1999, allows data
centers to continue to power electronic equipment upon activation of a Gaseous
Agent Total Flooding System. This exception was made for data centers that meet
the following risk considerations of Economic loss that could result from:
• Loss of function or loss of records
• Loss of equipment value
• Loss of life
• Risk of fire threat to the installation, occupants & property

5. Internal -General Use
Total Flooding Fire Extinguisher Systems
•Series of high pressure extinguisher agent tanks
•A gaseous agent is a gaseous chemical compound that extinguishes the fire by either removing heat or oxygen or both.
Flooded Fire Extinguishers
Inert Gases (Pro-Inert, Inergen)
FlourineBased (FM 200, Novec1230, FE
227)

6. Internal -General Use
Pre-action & Sprinkler System
Pre-action System
Requires an initial detection before
water is released, suitable for areas
with sensitive equipment.
Sprinkler System
Automatic system releasing water when
high heat is detected, effectively
suppressing fires.

7. Internal -General Use
Water Leak Detection & Rodent Repellent System
Leak Detection
Monitors water presence to prevent
hardware damage and potential corrosive
effects on electrical components.
Rodent Repellent
Protects data center equipment from rodent
infestations and potential damage to wiring
and insulation.
