Here is the quickie on arc fault and gfci issues regarding Fire/burg systems etc. per new NEC 70 which seems to be causing confusion
Arc fault protection is required if smoke alarms being installed in a bedroom are the 120vac type if the smoke detectors are low voltage and attached to a fire/burg panel they do not need arc fault protection.
If the outlet you are plugging the power supply for the fire/burg panel is in a bedroom area that outlet would need arc fault protection if it is new construction or newly installed.
Regarding gfci protection if the fire/burg panel power supply transformer is plugged in to an area such as unfinished basement ,garage etc which requires gfci protection. A single purpose dedicated outlet just for the fire/burg system can be installed and does not need gfci protection so a gfci nuisance trip will not interfere with system operation.
