i am working on an old honeywell fire system in a 20 story building. i
keep getting an a/c power loss error but i am not losing a/c power. i
put a fluke recorder on both the 120v input and 29vdc output and
havent seen more than a .3v change in either. ive tryed new power
supplies, boards, and input power source. any ideas what might be
causing this?
