FLSD Building Systems and Elevators 5

Question 1

A sprinkler head activates on the 15th floor. Which combination of actions should the FLSD take FIRST?

Accepted Answer

Confirm the alarm, notify the fire department, and investigate the activated floor

Answer

The FLSD must first confirm the alarm is real, ensure the fire department has been notified (which the monitoring company typically handles), and investigate the source floor.

Question 2

Which building system is specifically designed to keep stairwells free of smoke during a fire to allow safe evacuation?

Accepted Answer

Stairwell pressurization system

Answer

Stairwell pressurization systems inject outside air into stairwells, creating positive pressure that prevents smoke from entering and keeps egress paths clear.

Question 3

What is the role of the 'fire command center' (FCC) in a high-rise building during an emergency?

Accepted Answer

It is the central location for monitoring and controlling fire and life-safety systems

Answer

The fire command center is the hub where the FLSD and firefighters can monitor alarms, control HVAC smoke modes, communicate with occupants, and coordinate emergency response.

Question 4

If an elevator is 'recalled' to the lobby during a fire alarm and the doors open but then immediately close, what is the MOST likely cause?

Accepted Answer

An obstruction in the door path triggered the safety reversal

Answer

Elevator doors have safety sensors; if something blocks the door path during the open cycle, the safety reversal closes the doors, which is normal protective behavior.

Question 5

In a high-rise building, the FLSD notices that a floor's smoke detector has been in 'alarm bypass' status for two weeks due to renovation work. What is the correct course of action?

Accepted Answer

Ensure an approved fire watch is in place and document the impairment per code

Answer

When a fire protection system or component is impaired, NYC fire code requires an approved fire watch and formal impairment documentation until the system is restored.
