FACP FACP System Integration & Interfaces 2 — Questions and Answers
Question 1: What is the purpose of a fire alarm system's interface with a magnetic door holder?
- To release the door holder and allow a fire door to close automatically upon alarm (Correct answer)
- To lock exit doors during a fire alarm
- To open emergency exits remotely
- To hold all doors open for evacuation
Correct answer: To release the door holder and allow a fire door to close automatically upon alarm
Magnetic door holders keep fire doors open for convenience; upon fire alarm activation, the FACP de-energizes the magnet, allowing the door to close and prevent fire spread.
Question 2: In a mass notification system (MNS) integrated with a FACP, which NFPA standard provides the primary guidance?
- NFPA 72, Chapter 24 (Correct answer)
- NFPA 101, Chapter 7
- NFPA 13, Section 6
- NFPA 70, Article 760
Correct answer: NFPA 72, Chapter 24
NFPA 72 Chapter 24 covers emergency communication systems including mass notification systems that may be integrated with or interface with fire alarm control panels.
Question 3: When integrating a FACP with a Building Management System (BMS) via BACnet, what must the technician verify?
- That the BACnet object mapping correctly reflects fire alarm points and that the BMS cannot override fire alarm outputs (Correct answer)
- That the BMS has full control over all FACP outputs
- That the FACP is powered by the BMS
- That BACnet replaces the dedicated fire alarm network
Correct answer: That the BACnet object mapping correctly reflects fire alarm points and that the BMS cannot override fire alarm outputs
BACnet integration must be configured so the BMS can monitor fire alarm status but cannot override or control life-safety outputs, preserving the integrity of the fire alarm system.
Question 4: A FACP controls a pre-action sprinkler system. Which two inputs must typically both be present before the pre-action valve opens?
- A fire alarm signal from the detection system AND operation of a sprinkler head (or second alarm) (Correct answer)
- Only a waterflow switch signal
- Only a manual pull station activation
- A supervisory signal and a trouble signal
Correct answer: A fire alarm signal from the detection system AND operation of a sprinkler head (or second alarm)
Pre-action systems require a 'double interlock' — typically a fire detection signal plus confirmation of a sprinkler head operation — before releasing water, reducing accidental discharge.
Question 5: Which interface is used to connect a FACP to a remote annunciator panel located at the building's main entry?
- A dedicated annunciator circuit or RS-485 data bus depending on the panel manufacturer (Correct answer)
- A standard 120V AC power feed
- A fiber optic backbone only
- A wireless Z-Wave network
Correct answer: A dedicated annunciator circuit or RS-485 data bus depending on the panel manufacturer
Remote annunciators connect via a proprietary RS-485 or similar data bus (or dedicated wiring circuit) defined by the FACP manufacturer to display panel status at a remote location.
Question 6: A FACP is being integrated with a kitchen hood suppression system. What signal does the suppression system typically send to the FACP upon activation?
- An alarm signal via a dry contact relay wired to an IDC or monitor module (Correct answer)
- A supervisory signal via the SLC
- A trouble signal via the NAC
- A reset signal to the control panel
Correct answer: An alarm signal via a dry contact relay wired to an IDC or monitor module
Kitchen hood suppression systems use a dry contact output from their control panel to trigger an alarm at the FACP through a monitor module or dedicated IDC zone.
