For a Fire Alarm Panel, if the incoming power supply is UPS power supply, it is still required to add a local battery charger with batteries as UPS? Or we can take the incoming UPS power supply as secondary power to the Fire Alarm Panel?
I need to look how NFPA 72 reads.
My questions would be can the back up supply the stand by and alarm time required
What else is being supplied by the ups
Does the fire alarm need deicated back up power
In 2013 NFPA 72 look at 10.6.4
UPS was allowed starting with the 2010 edition,,,, BUT
Look at all the requirements that have to be met.
