Emergency Response Procedures Flashcards

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?

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.

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

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.

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

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.

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

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.

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

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.

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?

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.

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

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.

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

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.

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:

Answer: 60 seconds

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

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

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.

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

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.

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

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.

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:

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.

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

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.

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

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.

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

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.

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

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.

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

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.

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:

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).

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

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.
