S95 Emergency Response Procedures — Questions and Answers

Question 1: When a fire alarm system goes into alarm during a scheduled maintenance window, what is the FIRST action a fire alarm system supervisor should take?

Silence the alarm and resume maintenance
Notify the fire department and occupants immediately (Correct answer)
Check the maintenance log to see if the alarm is expected
Reset the control panel and wait to see if it re-activates

Correct answer: Notify the fire department and occupants immediately

Even during a scheduled maintenance window, a fire alarm activation must be treated as a real emergency until confirmed otherwise, requiring immediate notification of the fire department and occupants.

Question 2: Which NFPA standard specifically governs the inspection, testing, and maintenance of fire alarm systems in the US?

NFPA 1
NFPA 72 (Correct answer)
NFPA 101
NFPA 13

Correct answer: NFPA 72

NFPA 72, the National Fire Alarm and Signaling Code, is the primary standard that governs inspection, testing, and maintenance of fire alarm systems.

Question 3: A building's fire alarm control unit (FACU) displays a 'trouble' signal rather than an alarm signal. What does this indicate?

A confirmed fire event is in progress
A sprinkler head has activated
A fault or supervisory condition exists in the system that requires attention (Correct answer)
The system has been placed in test mode

Correct answer: A fault or supervisory condition exists in the system that requires attention

A trouble signal on an FACU indicates a fault or supervisory condition—such as a wiring break, low battery, or disabled device—that requires investigation and correction.

Question 4: During a fire alarm activation, the Incident Command System (ICS) assigns a Fire Alarm Supervisor. This person's PRIMARY role is to:

Evacuate all occupants personally
Serve as liaison between the FACU and incident commander, reporting system status (Correct answer)
Fight the fire until firefighters arrive
Disable non-essential alarm zones to reduce confusion

Correct answer: Serve as liaison between the FACU and incident commander, reporting system status

The Fire Alarm Supervisor serves as the technical liaison to the incident commander, providing real-time system status including which zones alarmed, elevator recall status, and door hold-open releases.

Question 5: An emergency action plan (EAP) requires that fire alarm supervisors maintain a log of all alarm activations. This log must include:

Only false alarms to track system reliability
Date, time, zone, cause, and actions taken for every activation (Correct answer)
Only activations that required fire department response
Monthly summary totals without individual event details

Correct answer: Date, time, zone, cause, and actions taken for every activation

A complete alarm log must document the date, time, zone activated, determined cause, and all actions taken for every activation to support investigation, code compliance, and pattern analysis.

Question 6: When a fire alarm is activated in a high-rise building, elevator recall is initiated. Which floor should elevators return to under Phase I recall?

The floor directly below the alarmed floor
The highest floor in the building
The designated primary lobby level or alternate recall floor if the lobby is threatened (Correct answer)
The floor where maintenance personnel are located

Correct answer: The designated primary lobby level or alternate recall floor if the lobby is threatened

Phase I elevator recall returns all elevators to the designated primary recall floor (typically the lobby), or an alternate recall floor if the primary floor is threatened by the alarm zone.

Question 7: A fire alarm supervisor receives notice that the monitoring company failed to receive a signal test transmission. The CORRECT response is to:

Document the failure and schedule a re-test within 30 days
Immediately investigate the communication pathway and restore it, posting a fire watch if required by code (Correct answer)
Manually call the fire department at the next scheduled check-in
Place a note in the logbook and wait for the next scheduled transmission test

Correct answer: Immediately investigate the communication pathway and restore it, posting a fire watch if required by code

A failed signal transmission means the system cannot report alarms to the monitoring center, requiring immediate investigation and a fire watch if the outage cannot be quickly corrected per NFPA 72.

Question 8: A voice evacuation system in a high-rise building typically uses which evacuation strategy to reduce stairwell congestion?

Total simultaneous evacuation of all floors
Defend-in-place with no evacuation announced
Staged or phased evacuation, starting with the fire floor and floors immediately above and below (Correct answer)
Evacuate only floors above the fire, leaving lower floors in place

Correct answer: Staged or phased evacuation, starting with the fire floor and floors immediately above and below

High-rise voice evacuation systems use staged (phased) evacuation, prioritizing the fire floor and adjacent floors first, to prevent dangerous stairwell overcrowding and allow orderly egress.

Question 9: Under NFPA 72, the maximum acceptable end-to-end response time for a supervising station to retransmit an alarm signal to the fire department is:

30 seconds
60 seconds (Correct answer)
90 seconds
120 seconds

Correct answer: 60 seconds

NFPA 72 requires that supervising stations retransmit a received alarm signal to the fire department within 60 seconds of receipt.

Question 10: During a fire alarm event, a building supervisor is asked by firefighters to perform a 'positive alarm sequence' reset. This action:

Immediately silences all audible and visible devices
Allows a trained operator up to 3 minutes to investigate before the general alarm sounds, applicable only to certain system types (Correct answer)
Resets all initiating devices to normal status
Transfers control of the system to the fire department

Correct answer: Allows a trained operator up to 3 minutes to investigate before the general alarm sounds, applicable only to certain system types

Positive alarm sequence (PAS) gives a trained operator a defined investigation period (up to 3 minutes per NFPA 72) before the general occupant alarm activates, and is only permitted in specific occupancy types.

Question 11: A supervisory signal on a fire alarm panel indicating 'SPRINKLER VALVE CLOSED' means the supervisor must IMMEDIATELY:

Note it in the log and investigate during normal business hours
Investigate and restore the valve to the open position, or implement a fire watch if the valve cannot be immediately reopened (Correct answer)
Evacuate the building and call 911
Reset the panel to clear the supervisory signal

Correct answer: Investigate and restore the valve to the open position, or implement a fire watch if the valve cannot be immediately reopened

A closed sprinkler control valve disables fire suppression in that zone, requiring immediate investigation to restore the valve or, if delayed, implementation of a fire watch per NFPA 25.

Question 12: During post-incident review after a fire alarm activation, which document is MOST useful for reconstructing the sequence of events?

The building's original architectural drawings
The fire alarm control panel's event history log (printout or electronic record) (Correct answer)
The manufacturer's installation manual for the smoke detectors
The annual inspection certificate

Correct answer: The fire alarm control panel's event history log (printout or electronic record)

The FACU's event history log records time-stamped activations, resets, silences, and trouble conditions, providing a precise chronological record of every system event during an incident.

Question 13: A fire alarm supervisor working in an area with explosive atmospheres (such as a paint spray booth) must ensure that all fire alarm equipment installed there is:

Painted with heat-resistant paint
Listed for use in hazardous (classified) locations per NEC Article 500 (Correct answer)
Installed at least 10 feet from all flammable materials
Equipped with double-pole disconnect switches

Correct answer: Listed for use in hazardous (classified) locations per NEC Article 500

In hazardous classified locations, all electrical equipment including fire alarm devices must be listed for the specific class and division of the hazardous atmosphere per NEC Article 500 to prevent ignition.

Question 14: When testing a duct smoke detector installed in an HVAC system, the test must verify that activation of the detector:

Only sounds the building alarm without affecting HVAC operation
Shuts down the associated air handling unit and triggers the fire alarm system (Correct answer)
Increases airflow to dilute smoke concentration
Activates only the local HVAC alarm without triggering the building fire alarm panel

Correct answer: Shuts down the associated air handling unit and triggers the fire alarm system

Duct smoke detectors must shut down the associated air handling unit to prevent smoke spread via ductwork and must also trigger the building fire alarm system per NFPA 72 and NFPA 90A.

Question 15: A carbon monoxide (CO) detector integrated into a fire alarm system activates. Under NFPA 720, the building supervisor must treat this as:

A nuisance alarm unless confirmed by a CO meter reading above 70 ppm
A life safety emergency requiring immediate evacuation and fire department notification (Correct answer)
A maintenance issue to be resolved by the HVAC technician only
An informational alert that does not require occupant notification

Correct answer: A life safety emergency requiring immediate evacuation and fire department notification

NFPA 720 requires CO alarm signals to be treated as life safety emergencies, triggering occupant notification and emergency services response, since CO is colorless, odorless, and immediately dangerous to life.

Question 16: During a fire, a fire alarm supervisor is directed to use the 'firefighter's telephone' system. This system is designed to:

Call the monitoring center automatically when fire department personnel arrive
Provide two-way voice communication between firefighters at various locations and the fire command center (Correct answer)
Broadcast pre-recorded evacuation instructions to all floors simultaneously
Automatically unlock all stairwell doors upon fire department entry

Correct answer: Provide two-way voice communication between firefighters at various locations and the fire command center

The firefighter's telephone system provides dedicated two-way voice communication between the fire command center and firefighters at remote jacks throughout the building for coordinating suppression and rescue operations.

Question 17: A fire alarm system that uses addressable technology (as opposed to conventional zoning) provides the advantage of:

Lower upfront equipment cost
Identifying the exact device that activated, pinpointing the alarm location (Correct answer)
Eliminating the need for annual inspections
Operating without a connection to a supervising station

Correct answer: Identifying the exact device that activated, pinpointing the alarm location

Addressable systems assign a unique address to each device, allowing the FACU to identify exactly which detector, pull station, or other device activated, which speeds emergency response and troubleshooting.

Question 18: Under NFPA 72, a central station monitoring company must maintain records of all alarm signals received for a minimum of:

6 months
1 year (Correct answer)
3 years
5 years

Correct answer: 1 year

NFPA 72 requires central station supervising companies to retain records of all signals received, including alarms, troubles, and supervisory signals, for a minimum of 1 year.

Question 19: If a fire alarm system's primary power supply fails and the system switches to secondary (battery) power, NFPA 72 requires the batteries to power the system in standby mode for at least:

4 hours followed by 5 minutes of alarm
24 hours followed by 5 minutes of alarm
24 hours followed by 15 minutes of alarm (Correct answer)
72 hours followed by 30 minutes of alarm

Correct answer: 24 hours followed by 15 minutes of alarm

NFPA 72 requires secondary power (batteries) to sustain the fire alarm system in standby for a minimum of 24 hours, followed by at least 5 minutes of full alarm operation (15 minutes for voice/evacuation systems).

Question 20: A fire alarm supervisor who deliberately silences a fire alarm without investigating, resulting in delayed evacuation and injury, may face:

Only a written warning from building management
Civil liability and potential criminal charges depending on jurisdiction (Correct answer)
Loss of insurance coverage for the building only
A mandatory 30-day suspension of their certificate

Correct answer: Civil liability and potential criminal charges depending on jurisdiction

Deliberately suppressing a fire alarm without investigation can constitute negligence or criminal recklessness, exposing the supervisor to both civil liability (lawsuits) and criminal prosecution if injuries result.

Question 21: A building owner requests that a fire alarm supervisor bypass (disable) a smoke detector in a hotel room because guests have repeatedly complained about false alarms from steam. The correct response is to:

Disable the detector immediately to resolve the guest complaint
Refuse to disable the detector and instead investigate the root cause, recommending a detector type appropriate for the environment (Correct answer)
Disable the detector during occupied hours and restore it at night
Replace it with a heat detector without notifying the AHJ

Correct answer: Refuse to disable the detector and instead investigate the root cause, recommending a detector type appropriate for the environment

Disabling a required life safety device without AHJ approval is a code violation; the supervisor must investigate the nuisance cause and recommend appropriate corrective action such as a different detector technology.
