F89 F89 Communication Systems and Emergency Notifications Questions and Answers 5 — Questions and Answers
Question 1: When an F89 Fire and Life Safety Director gives an 'all clear' announcement, what must be confirmed BEFORE making that announcement?
- The fire department incident commander has authorized the all clear (Correct answer)
- The building's sprinkler system has been reset
- All elevators have returned to normal service
- The primary power supply has been restored
Correct answer: The fire department incident commander has authorized the all clear
Only the fire department incident commander has authority to declare an all clear; the FLSD must receive that authorization before announcing it.
Question 2: Which of the following is a key reason the fire command station (FCS) must be located in the building lobby or a similarly accessible location?
- To allow arriving fire department personnel immediate access to alarm controls and communications (Correct answer)
- To reduce cable runs and lower installation cost
- To comply with ADA requirements for accessible equipment
- To prevent unauthorized access to the sprinkler riser
Correct answer: To allow arriving fire department personnel immediate access to alarm controls and communications
The FCS must be accessible to responding firefighters who need to quickly assess alarm conditions and control voice communications upon arrival.
Question 3: A building's emergency communication system uses a 'positive alarm sequence.' What does this feature do?
- Allows a brief delay for trained staff to investigate before full alarm activation (Correct answer)
- Automatically silences the alarm after 30 seconds if no second detector activates
- Sends an automatic signal to the fire department without staff involvement
- Activates all notification appliances immediately upon any single detector activation
Correct answer: Allows a brief delay for trained staff to investigate before full alarm activation
Positive alarm sequence permits an approved delay during which staff can investigate an alarm before system-wide notification occurs, reducing nuisance alarms.
Question 4: Under New York City high-rise fire safety rules, the fire safety director must be available at the fire command station within how many minutes of an alarm activation?
- Within 1 minute (Correct answer)
- Within 3 minutes
- Within 5 minutes
- Within 10 minutes
Correct answer: Within 1 minute
NYC fire safety regulations require the fire safety director or deputy to be at the fire command station within 1 minute of alarm activation.
Question 5: What is the primary function of a 'trouble signal' generated by the fire alarm control panel?
- To indicate a fault or abnormal condition in the system that requires service (Correct answer)
- To signal that a fire has been confirmed and suppression has activated
- To notify occupants to begin evacuation immediately
- To test the notification appliances on a scheduled basis
Correct answer: To indicate a fault or abnormal condition in the system that requires service
A trouble signal alerts personnel to a system abnormality such as a wiring fault, low battery, or disabled device requiring technician attention.
Question 6: During a fire emergency, an occupant with a hearing impairment is not responding to audible alarms on the 22nd floor. Which notification appliance is SPECIFICALLY designed to alert this individual?
- Visible (strobe) notification appliance (Correct answer)
- Low-frequency sounder (520 Hz)
- Tactile alerting device
- Firefighter telephone handset
Correct answer: Visible (strobe) notification appliance
Visible strobe appliances are the standard ADA-compliant devices installed to alert occupants who cannot perceive audible alarms.
Question 7: A warden reports that the corridor speaker on the 15th floor is emitting a distorted, garbled voice message during a drill. What is the MOST likely cause?
- A damaged or failed speaker cone or a loose wiring connection to that speaker (Correct answer)
- Incorrect placement of the fire command station microphone
- A software error in the fire alarm control panel
- Feedback from the building's public address (PA) system
Correct answer: A damaged or failed speaker cone or a loose wiring connection to that speaker
Distortion limited to a single speaker typically results from physical damage to the speaker cone or a loose/corroded wiring connection at that device.
