One of the requirements of NFPA is the regular testing of emergency generators. This testing helps to ensure that generator powered backup lighting will operate as expected and that proper signage will be in place to illuminate egress paths if backup lighting should fail. There are two types of tests that must be performed:
- It is required that a monthly test be performed on Level 1 and Level 2 generators. A Level 1 generator is one whose failure could result in death or serious injury. A level 2 generator is one whose failure would not result in life-threatening injury. During testing, a generator should operate under available load for a minimum of thirty minutes.
- If a generator fails the monthly test, it should be operated under a load supplied by a load bank (i.e. load bank testing) for two continuous hours each year.
Monthly and annual generator tests are important measures for preparing generators for power outages, but they should not be the only measures. It is also important for building owners to make sure that their generators receive scheduled maintenance, annual infrared scanning, and modernization and retrofitting, as necessary. Testing is designed to test a generator’s efficiency, but maintaining or improving that efficiency requires a diverse approach that includes the measures above.
VFS is pleased to announce that we can provide this service for our building owner clients. We offer both the monthly testing and the annual testing as required by NFPA. If you are a building owner, contact VFS today to learn more about out services and how we can help you to stay in compliance.
