  1. 65 dBA
  2. 85 dBA
  3. 105 dBA
  4. 75 dBA Correct answer.

Explanation

Public mode audibility requires at least 75 dBA at 10 ft from the appliance, and also at least 15 dBA above the average ambient level. A higher ambient level raises the required output above 75 dBA.

Question 31Fire Alarm System Fundamentals and Design

What are the two core functions of a fire alarm control panel?

  1. Provide emergency lighting and exit signage on egress paths
  2. Regulate building HVAC and elevator power during normal use
  3. Supply water to the sprinkler piping and record flow data at the riser
  4. Monitor initiating devices and operate notification appliances Correct answer.

Explanation

The control panel receives and interprets signals from initiating devices, then controls notification appliances and any interfaced systems according to its programmed logic. Water supply, lighting, and HVAC regulation are functions of other building systems.

Question 32Fire Alarm System Fundamentals and Design

A fixed-temperature heat detector operates when the sensing element reaches what condition?

  1. The element reaches a preset temperature Correct answer.
  2. Smoke particles in the chamber scatter a light beam
  3. The ambient light level in the space drops sharply
  4. The relative humidity in the protected space rises

Explanation

A fixed-temperature device responds when its heat-sensitive element reaches a predetermined set point. Rate-of-rise and rate-compensated devices are different operating principles.

Question 33Fire Alarm System Fundamentals and Design

A protected-premises fire alarm system's secondary power supply must be able to operate the system for at least how long?

  1. 60 hours of standby followed by 15 minutes of alarm
  2. 24 hours of standby followed by 5 minutes of alarm Correct answer.
  3. 4 hours of standby followed by 5 minutes of alarm
  4. 24 hours of standby followed by 30 minutes of alarm

Explanation

NFPA 72 requires the secondary supply to maintain the system in standby for 24 hours and then be capable of operating it in alarm for 5 minutes. Longer standby or alarm periods apply where local codes or occupancy conditions demand them.

Question 34Fire Alarm System Fundamentals and Design

What distinguishes a Class A initiating device circuit from a Class B circuit?

  1. It can be installed only with fiber-optic cable
  2. It is exempt from electrical supervision requirements
  3. It still works with a single open conductor Correct answer.
  4. It may connect no more than two devices

Explanation

A Class A circuit is wired so that a single open or ground fault on the pathway does not prevent the devices beyond the fault from operating and signaling. Class B circuits lose the devices beyond a single break.

Question 35Fire Alarm System Fundamentals and Design

A 20 ft by 20 ft room has a 10 ft ceiling and a visible appliance mounted on the wall. What is the minimum candela rating allowed?

  1. 7.5 cd
  2. 2 cd
  3. 15 cd Correct answer.
  4. 110 cd

Explanation

For a room no larger than 20 ft by 20 ft with the appliance at the standard mounting height, 15 cd is the minimum listed rating. Larger rooms or longer viewing distances require higher candela values from the published tables.

Question 36Fire Alarm System Fundamentals and Design

Which device initiates Phase I elevator recall of the cars to a designated floor?

  1. A waterflow switch in the sprinkler riser
  2. A smoke detector in the elevator lobby Correct answer.
  3. A manual pull station on any building floor
  4. A duct detector in the supply air duct

Explanation

Smoke detectors in the elevator lobby, machine room, and hoistway pit are the typical inputs for Phase I recall, which returns cars to the designated alternate level. The resulting power shutdown is a separate Phase I function.

Question 37Fire Alarm System Fundamentals and Design

How does cross-zoning reduce unwanted alarms?

  1. It raises the detector sensitivity after dark
  2. It silences the horns after a fixed delay
  3. It requires two detectors to alarm first Correct answer.
  4. It verifies alarms by calling the premises

Explanation

Cross-zoning requires alarm signals from two independent detectors or zones before the system takes the action being protected against. A single detector actuation, such as one triggered by an aerosol, does not produce the final output.

Question 38Fire Alarm System Fundamentals and Design

What is the purpose of alarm verification?

  1. To test battery capacity during standby
  2. To increase the volume of the notification appliances
  3. To delay alarm processing and reduce nuisance alarms Correct answer.
  4. To confirm device address programming

Explanation

Alarm verification briefly resets and rechecks a smoke detector before processing the alarm, so a transient condition does not cause an unwanted response. When verification is used, any verified alarm must still be processed without further delay.

Question 39Fire Alarm System Fundamentals and Design

With 30 ft spacing on a smooth ceiling, what is the greatest distance permitted from any ceiling point to the nearest smoke detector?

  1. 10 ft
  2. 30 ft
  3. 21 ft Correct answer.
  4. 15 ft

Explanation

The coverage radius is 0.7 times the listed spacing, so a 30 ft spacing yields a maximum distance of 21 ft from any point to the nearest detector. The 15 ft figure applies to the distance from a detector to a sidewall.

Question 40Fire Alarm System Fundamentals and Design

A sprinkler system tamper switch sends a supervisory signal when which condition occurs?

  1. The system pressure exceeds its rating
  2. A sprinkler head fuses open
  3. A control valve is closed from its normal position Correct answer.
  4. Water flows through the riser

Explanation

Tamper switches monitor the position of control valves so that a closed valve is reported as a supervisory condition, not an alarm. Waterflow switches, by contrast, report actual water movement.

Question 41Fire Alarm System Fundamentals and Design

What minimum distance must be maintained between a spot-type smoke detector and an air supply diffuser?

  1. At least 36 in. Correct answer.
  2. At least 6 in.
  3. At least 72 in.
  4. At least 12 in.

Explanation

Detectors must be kept at least 36 in. from air supply diffusers and other airflow openings so that supply air does not dilute or blow smoke away from the sensing chamber. Greater distances may be needed where diffuser velocity is high.

Question 42Fire Alarm System Fundamentals and Design

In a sleeping area, audible notification appliances must produce what minimum sound level at the pillow?

  1. 85 dBA
  2. 55 dBA
  3. 65 dBA
  4. 75 dBA Correct answer.

Explanation

NFPA 72 requires a sound level of at least 75 dBA at the pillow in sleeping areas to help awaken occupants. This is in addition to the general public mode requirement of 15 dBA above ambient.

Question 43Fire Alarm System Fundamentals and Design

What is the main advantage of an addressable fire alarm system over a conventional system?

  1. It identifies each device individually at the panel Correct answer.
  2. It requires no secondary power supply
  3. It eliminates the need for a control panel
  4. It uses only two wires throughout the building

Explanation

In an addressable system each device has its own address, so the panel can report the specific device in alarm or trouble. Conventional systems report only the zone or circuit that contains the device.

Question 44Fire Alarm System Fundamentals and Design

A notification appliance circuit supplies power to which group of devices?

  1. Smoke and heat detectors
  2. Horns, strobes, and speakers Correct answer.
  3. Waterflow and pressure switches
  4. Manual pull stations and tamper switches

Explanation

Notification appliance circuits carry operating power to audible and visible signaling devices such as horns, strobes, chimes, and speakers. Initiating devices are connected to initiating device circuits or signaling line circuits instead.

Question 45Fire Alarm System Fundamentals and Design

In a positive alarm sequence, what acknowledgment and investigation times apply before the alarm must be transmitted?

  1. Acknowledge within 180 seconds and investigate within 15 seconds
  2. Acknowledge within 30 seconds and investigate within 90 seconds
  3. Acknowledge within 60 seconds and complete the investigation within 300 seconds
  4. Acknowledge within 15 seconds and investigate within 180 seconds Correct answer.

Explanation

A positive alarm sequence requires trained personnel to acknowledge the signal at the panel within 15 seconds and to investigate within 180 seconds. If the signal is not acknowledged within 15 seconds, the system must process the alarm immediately.

Question 46Fire Alarm System Fundamentals and Design

A system draws 0.5 A in standby for 24 hours and 3.0 A in alarm for 5 minutes. Applying the required 20 percent derating, what minimum battery capacity is needed?

  1. 15.3 Ah Correct answer.
  2. 12.3 Ah
  3. 14.7 Ah
  4. 18.4 Ah

Explanation

Standby energy is 0.5 A times 24 h, or 12 Ah, and alarm energy is 3.0 A times 5/60 h, or 0.25 Ah, for a total of 12.25 Ah. Dividing by 0.8 to add the 20 percent aging margin gives about 15.3 Ah.

Question 47Fire Alarm System Fundamentals and Design

A sprinkler waterflow switch must initiate an alarm signal within what time after water begins to flow?

  1. 5 minutes
  2. 10 seconds
  3. 90 seconds Correct answer.
  4. 30 seconds

Explanation

Waterflow switches are required to initiate an alarm within 90 seconds of water flow, which allows for normal pressure surges without delaying a real alarm. The switch must also be listed to operate at the minimum flow stated by the standard.

Question 48Fire Alarm System Fundamentals and Design

A fire alarm control panel must be listed for releasing device service whenever the system does what?

  1. Monitors duct detectors to shut down air handlers
  2. Sounds horns and strobes throughout a large building
  3. Controls elevator recall and shunt trip functions
  4. Actuates a clean-agent or deluge suppression system Correct answer.

Explanation

Panels that control suppression system releasing devices must be listed specifically for releasing service because of the hazard of an unintended discharge. Ordinary detection and notification panels are not evaluated for that function.

Question 49Fire Alarm System Fundamentals and Design

What minimum number of spot-type smoke detectors is needed for a smooth, unobstructed ceiling measuring 60 ft by 40 ft?

  1. 3
  2. 2
  3. 4 Correct answer.
  4. 6

Explanation

With 30 ft spacing, the 60 ft dimension needs two rows and the 40 ft dimension needs two columns, giving four detectors. Three detectors cannot keep every point within the 21 ft coverage radius.

Question 50Fire Alarm System Fundamentals and Design

A fire alarm system sends a signal indicating that a sprinkler control valve has been closed. This signal is classified as which type?

  1. Supervisory signal Correct answer.
  2. Alarm signal
  3. Trouble signal
  4. Pre-alarm signal

Explanation

NFPA 72 recognizes alarm, supervisory, and trouble signals as distinct types. A supervisory signal indicates an off-normal condition of a system or protected-property component whose impairment could reduce the system's effectiveness, such as a closed control valve. It is not a fire alarm and is not an electrical fault.
