• A building’s fire alarm system required by code must be inspected and

tested at least how often?

• Monthly
• Quarterly
• Semi-annually
• Annually

B Quarterly testing is the minimum frequency required for routine fire alarm system inspection and testing under citywide maintenance requirements.

• When verifying corrective action on a previously cited fire alarm

system defect, the inspector must ensure that: 1 / 4

• The system panel displays “Normal” status.
• The fire alarm control panel still shows “Trouble” but has a note.
• Only manual pull stations are tested.
• Notification appliances are disabled during the test.

A A “Normal” status confirms that all faults have been cleared and the system is restored to full operational condition.

• Under the applicable codes, a fire alarm system’s backup power

supply must sustain full load operation for at least:

• 15 minutes
• 30 minutes
• 60 minutes
• 90 minutes

C Code mandates require backup power that can support the system under full load for a minimum of 60 minutes following a power failure.

• Which of the following defects would prevent certification of

correction?

• A missing cover on a junction box with wiring intact and secured.
• A supervisory device still showing “Supervisory” status.
• A broken lens on a hallway strobe accessory.
• A manual pull station missing directional signage, but pull station 2 / 4

functional.B A supervisory condition indicates the system is not in fully normal status; the defect must be cleared to certify correction.

• The audible volume level of a fire alarm horn in a residential corridor

must be:

• At least 65 dBA at 10 ft.
• At least 75 dBA at 10 ft.
• At least 85 dBA at 10 ft.
• At least 95 dBA at 10 ft.

C Codes require audible devices to produce a minimum of 85 dBA at 10 feet to ensure adequate occupant warning.

• When a previously nonfunctional manual pull station is replaced, the

inspector must verify:

• The new device is painted the same color as the wall.
• The new device activates the fire alarm control panel and causes full

system alarm.

• The new device has a removable break glass covering.
• The new device is mounted within 8 feet of the floor.

7. A “Trouble” signal on a fire alarm control panel indicates:

• A fire has been detected.
• The system is in supervisory mode.
• There is a fault or impairment in the system.
• The system passed testing.

C “Trouble” status specifically denotes a fault such as wiring, power, or device failure that affects system integrity.

• For which of the following conditions can a temporary variance be

granted rather than requiring immediate correction?

• A totally nonfunctional fire alarm system.
• Broken fire alarm control panel with no backup panel.
• A missing battery cover on backup battery cabinet.
• Entire alarm wiring exposed in a public corridor.

C Minor defects like a missing battery cover may allow temporary variance, assuming no hazard to system operation.

• After correcting a water-flow supervisory device defect, what must the

inspector do?

• Document only the date of correction.
• Verify that the water-flow signal is properly supervised and sends a

supervisory signal when tested.

• Reset the system and leave it untested.
