Data center backup systems
Generator, UPS & Cooling Readiness
Backup systems only help if they work when called. AAAT3 builds generator, UPS, transfer switch and cooling test programs with safe procedures and clean records, so your backups are proven before the utility fails.

Common questions
Why do UPS systems cause so many outages?
Uptime data shows UPS failures are the top cause of power outages, followed by transfer switches and generators. Poor maintenance and testing are common factors.
How often should generators be tested?
NFPA 110 sets monthly testing for many emergency systems, with load requirements. Your authority having jurisdiction and clients may require more.
What is a fuel supply plan?
A plan for fuel storage, quality testing and priority deliveries during a long outage.
Can AAAT3 oversee our service vendors?
Yes. We make sure vendor work follows MOPs, permits and LOTO.
Do you plan for cooling failures?
Yes. We write response steps and run drills for chiller, CRAH and liquid cooling failures.
