Good afternoon all!

 

I work at a healthcare facility and I wanted to know what your interpretation of   NFPA 101-2012: 7.9.3; 7.10.9; NFPA 99-2012: 6.3.2.2.11.5 is with respect to testing battery-powered lighting.  Our facility has two electrical feeders and 100% generator back up. We have battery backed up lighting and exit signage that are on the life safety branch. Because we have additional layers of back up, is the battery testing still required for exit signage, lighting etc. that have the batteries?  Is the intent of the testing met because we exercise the emergency power system?
