FTTP battery backup and NFPA 72

[satman]

I'm looking for a real answer that I cannot seem to get from my FMO. Fire Marshal Office.

Question pertains to remote or central alarm stations connected to fiber optic interfaces for the only connection to the outside world.

Fiber optic interfaces have battery backup with a industry standard of 6-10 hours.

Old POTS (copper wire -48V) had 24-7 power backup at the CO (telco office).

Is the fiber optic infrastructure required to provide 24 or 60 hr UPS equipment to support a dial tone to fire alarm systems?

Does a residential home with a sprinkler system require a phone line connection and 60hr UPS?

Does a commercial building require a phone line connection 24 or 60hr UPS?

Washington State FMO only referenced 24 for the alarm panel, never mentioned 60hr battery for the alarm panel.


Sincerely,
satman

Why 60 hr. I think it will be burnt to the ground by then?

my guess =

a manufacturer of such devices has the patent on 60 hour backup batteries.

but, i am a bit of a cynic.
