Free FLSD Fire Alarm Systems Questions and Answers 1 — Questions and Answers
Question 1: An FLSD is on duty at the Fire Command Center when a yellow light illuminates on the Fire Alarm Control Panel (FACP) accompanied by a local buzzer. The panel indicates a "Supervisory" signal from a tamper switch on a 15th-floor sprinkler control valve. What is the most appropriate initial action for the FLSD to take?
- Immediately initiate a building-wide evacuation.
- Acknowledge the signal, silence the local buzzer, and dispatch building personnel to investigate the status of the valve. (Correct answer)
- Reset the fire alarm system to clear the signal.
- Wait for a second signal before taking any action.
Correct answer: Acknowledge the signal, silence the local buzzer, and dispatch building personnel to investigate the status of the valve.
A supervisory signal indicates an off-normal condition of a fire protection system, not an active fire. The correct procedure is to acknowledge the signal to silence the local buzzer and then promptly dispatch a trained staff member to investigate the cause, in this case, a potentially closed sprinkler valve, and restore it to its normal position. This action does not warrant a building evacuation or a full system reset until the condition is understood.
Question 2: Which of the following is considered a manual fire alarm initiating device?
- Smoke detector
- Heat detector
- Pull station (Correct answer)
- Sprinkler water flow switch
Correct answer: Pull station
A manual pull station requires human intervention to activate the fire alarm system. Smoke detectors, heat detectors, and water flow switches are all automatic initiating devices that activate when they sense specific conditions related to a fire, such as smoke, high temperature, or water movement in the sprinkler pipes.
Question 3: During a fire alarm activation, what is the primary responsibility of the Fire Life Safety Director (FLSD) from the Fire Command Center *before* the fire department arrives?
- Personally proceed to the fire floor to extinguish the fire.
- Operate the fire alarm control panel, implement the Fire Safety Plan, and communicate with building occupants. (Correct answer)
- Silence and reset the alarm system immediately to prevent panic.
- Evacuate the Fire Command Center and direct operations from outside the building.
Correct answer: Operate the fire alarm control panel, implement the Fire Safety Plan, and communicate with building occupants.
The FLSD's primary role is to manage the incident from the Fire Command Center. This includes operating the FACP, using the communication systems to provide instructions to occupants, and implementing the building's approved Fire Safety and Evacuation Plan. The FLSD coordinates the emergency response within the building until the fire department arrives and takes command.
Question 4: A 'trouble' signal on the Fire Alarm Control Panel (FACP) most likely indicates:
- A confirmed fire on the 10th floor.
- A tamper switch on a sprinkler valve has been activated.
- A fault or malfunction within the fire alarm system's wiring or components. (Correct answer)
- A pre-alarm condition indicating the potential for a fire.
Correct answer: A fault or malfunction within the fire alarm system's wiring or components.
A trouble signal indicates a fault within the fire alarm system itself, such as a broken wire, a malfunctioning device, or a power issue. It does not indicate an active fire (alarm) or an issue with a monitored system like a sprinkler valve (supervisory). It is a notification that the system's integrity is compromised and requires service.
Question 5: An FLSD receives a fire alarm from a smoke detector in an elevator lobby on the 22nd floor. According to standard procedure, what should happen to the elevators in that bank?
- All elevators in that bank should be sent to the 22nd floor for evacuation.
- Elevators should continue normal operation until the fire is confirmed.
- All elevators in that bank should immediately shut down in their current position.
- Phase I emergency recall should be initiated, sending the elevators to the designated recall level, typically the ground floor. (Correct answer)
Correct answer: Phase I emergency recall should be initiated, sending the elevators to the designated recall level, typically the ground floor.
The activation of an elevator lobby smoke detector is designed to automatically initiate Phase I emergency recall. This safety feature sends all elevators in the bank to the primary recall floor (usually the lobby) and takes them out of normal service to prevent them from opening on the fire floor and exposing occupants to danger.
Question 6: Which type of automatic detector is designed to activate when the temperature rises at an abnormally fast pace, such as 15 degrees in one minute?
- Ionization smoke detector
- Rate-of-rise heat detector (Correct answer)
- Photoelectric smoke detector
- Fixed-temperature heat detector
Correct answer: Rate-of-rise heat detector
A rate-of-rise heat detector is specifically designed to detect a rapid increase in temperature, which is a common characteristic of a developing fire. A fixed-temperature detector activates at a specific, predetermined temperature, while ionization and photoelectric detectors sense smoke particles.
An FLSD is on duty at the Fire Command Center when a yellow light illuminates on the Fire Alarm Control Panel (FACP) accompanied by a local buzzer.
The panel indicates a "Supervisory" signal from a tamper switch on a 15th-floor sprinkler control valve.
