Job Checkin

Bldg A has the battery troubles coming in and out. Facp aes and all nac panel batteries are due except for unit 110 nac those are dated 2020. Total of 2x 12v12ah and 7 x 12v 8ah needed to replace all due batteries in bldg A. I did not have the 12ah batteries on hand or enough 8 ah to replace all. The zone trouble comes in as zone 0 to the monitoring station so it’s not possible to tell which nac panel is exactly causing the trouble, all should be replaced. The trouble is intermittent and the nac panels did not show yellow light battery trouble when I was on site. The panel was normal when I arrived. History does show low battery intermittent trouble and teetotal. There are other bldgs with panels here that may have due batteries as well. Suggest replacing all due batteries in all buildings .
