After an initiating device (like a smoke detector or pull station) is triggered, NFPA 72 limits how long thecontrol unit can delay its responseto initiating notification appliances and/or signal transmission.

NFPA 72 (2022), Section 10.11.1.1:

“Fire alarm and emergency alarm initiating devices shall be arranged to initiate the intended alarm or response within 10 seconds unless otherwise permitted. The total delay shall not exceed 30 seconds.”

Correct answer: C. 30 seconds

Emergency voice/alarm communication systems must continue functioning after a loss of primary power for aminimum of 24 hours in standby, followed by15 minutes of alarmoperation.

NFPA 72 (2022), Section 10.6.7.2.1.1 (Exception):

“…followed by 15 minutes of alarm for emergency voice/alarm communication systems.”

This ensures that occupants can still hear evacuation messages even during a power outage.

Correct answer: D. Minimum of 15 minutes

Ground-fault monitoring circuits are required on many fire alarm systems to detect when a wire has unintentionally contacted a grounded surface. During testing, the inspectorintentionally introduces a groundto verify that the panel can detect it.

NFPA 72 (2022), Section 10.17.1:

"Ground-fault conditions shall be annunciated in accordance with the requirements of this Code."

Testing method:

Thestandard functional testis tointentionally ground a circuit(typically using a known resistor) and verify the control panel indicates aground-fault supervisory signal.

Correct answer: D. Verify the ground-fault indication when circuits are grounded
