NFPA 72 -Standby power to telephone modem

NFPA 72 addresses capacity of standby power for fire alarm systems.  In my circumstance, a client has changed their phone service from a traditional phone line to a cable internet modem.  The Fire alarm panel is equipped with batter back up standyby power but the modem is not.


Question:  for a non-critical infrastructure building, do you require the modem to be supplied with battery back up power as well?


The local alarm will still activate and alert occupants.  However, as installed, there would be no remote monitoring capabilities while the power is out.
