F01 F01 NYC Fire Alarm Systems and Devices 2 — Questions and Answers
Question 1: What is the purpose of a notification appliance circuit (NAC) in a fire alarm system?
- To detect smoke and heat
- To power the control panel
- To activate audible and visual alerting devices throughout the building (Correct answer)
- To communicate directly with the fire department
Correct answer: To activate audible and visual alerting devices throughout the building
The NAC connects the fire alarm panel to horns, strobes, and speakers that alert building occupants to an emergency.
Question 2: Under NYC regulations, what color are fire alarm pull stations typically required to be?
- Yellow
- Green
- Blue
- Red (Correct answer)
Correct answer: Red
NYC Fire Code requires manual fire alarm pull stations to be red for easy identification by occupants in an emergency.
Question 3: What is the role of a duct smoke detector installed in a building's HVAC system?
- To measure air temperature in ducts
- To detect smoke in air ducts and trigger HVAC shutdown (Correct answer)
- To increase airflow during a fire
- To alert occupants via speakers
Correct answer: To detect smoke in air ducts and trigger HVAC shutdown
Duct smoke detectors sense smoke in HVAC ducts and trigger automatic system shutdown to prevent smoke from spreading throughout the building.
Question 4: If a fire alarm system is placed in 'test mode,' which of the following is true?
- The system is fully operational and will alert FDNY
- Alarms activated during testing will not transmit to the monitoring station (Correct answer)
- All sprinklers are automatically disabled
- The system cannot detect any fire
Correct answer: Alarms activated during testing will not transmit to the monitoring station
When in test mode, alarm activations are suppressed at the central monitoring station to prevent false emergency dispatches during testing.
Question 5: What is a 'zone' in the context of a building fire alarm system?
- A specific floor where a fire has been confirmed
- A designated area or section of a building monitored by grouped detectors (Correct answer)
- The area directly around the fire alarm control panel
- A restricted-access area in the building
Correct answer: A designated area or section of a building monitored by grouped detectors
A zone groups multiple detectors in a specific building area so the FACP can identify which section triggered the alarm.
Question 6: Under NYC Fire Code, who is authorized to reset a fire alarm system after an activation?
- Any building occupant
- The building owner or managing agent without investigation
- A trained fire guard or authorized building representative after the cause is cleared (Correct answer)
- Only FDNY personnel
Correct answer: A trained fire guard or authorized building representative after the cause is cleared
Only a trained fire guard or authorized building representative may reset the fire alarm after the cause of activation has been investigated and cleared.
