- Circle the correct answer from the following statements: a. Always connect a fire alarm circuit or system to a power supply that has ground-fault circuit interrupter (GFCI) protection. b. Never connect a fire alarm circuit or system to a power supply that has ground-fault circuit interrupter (GFCI) protection. c. It makes no difference whether the branch circuit is GFCI or AFCI protected because the alarms are required to have battery backup power.
