I had to do a little reading but I think that I understand what you were saying about the RIB. You are saying to get a backup ps/battery for the 212 ps and have it switch based on the 212 supervisory zone, yes?DELInstallations said:I wouldn't recommend that...think about what happens at the 3-5 year mark on the M1 when the battery fails a self test (in the middle of the night) or as Murphy would dictate, while you are away on vacation.
If you put the listed 12 aH on the 212, that'll get you a hypothetical 6 hours fully loaded standby.
Lets go around this logically, what sort of standby is the M1 running?
There's other ways to skin the cat but you're going to need a RIB, another battery and PS/charger...
Have you used the power calc that Elk provides for battery sizing and standby calcs?
