Have you actually checked the battery after a low battery signal??? Is the =
battery really low?
 =20

Could be the system is giving you a false low battery indication.

With a new battery and the readings you gave, there's no way that you'd get=
 a low battery signal within 15 minutes of startup.=20

Also, I'm not familiar with the FBI panel but maybe you actually had a low =
battery and the low battery indication is (for some reason) locked into mem=
ory? Can you get into programming? If so, try removing low battery indicati=
on, and restart the panel. Or, maybe just default the panel and reprogram. =
Could just be something locked into memory ..... maybe???=20

With Napco, after receiving a low battery indication and changing the batte=
ry, it is required to do a bell test to put a load on the battery to let th=
e system know the battery can take a load. Don't remember about FBI. It's b=
een too long since I installed them.=20
