Question 1

What is the main function of a fire alarm system?

Accepted Answer

To alert occupants during a fire

Answer

The main function of a fire alarm system is to provide early detection of a fire and promptly alert building occupants. This crucial warning allows individuals sufficient time to evacuate safely and enables emergency services to respond quickly. Its primary role is to initiate the emergency response process and protect lives.

Question 2

Which component of a fire alarm system detects smoke particles?

Accepted Answer

Smoke detector

Answer

A smoke detector is specifically designed to detect the presence of smoke particles in the air, which are often the first indicators of a fire. Upon detection, it triggers the fire alarm system, providing an early warning to occupants. This early detection is critical for maximizing evacuation time and minimizing potential harm.

Question 3

What is the minimum duration emergency lighting must function during a power outage?

Accepted Answer

90 minutes

Answer

Most fire codes, including NFPA 101 Life Safety Code, mandate that emergency lighting systems must remain functional for a minimum of 90 minutes during a power outage. This duration ensures that occupants have sufficient illumination to safely navigate exit paths and evacuate the building, even in prolonged power failures. It is a critical safety requirement for egress.

Question 4

Which system uses water to suppress fires automatically?

Accepted Answer

Sprinkler system

Answer

A sprinkler system is an active fire protection system that automatically detects and suppresses fires using water. When activated by heat, individual sprinkler heads discharge water directly onto the fire, controlling or extinguishing it before it can spread significantly. This automatic response is highly effective in minimizing fire damage and protecting lives.

Question 5

Why are illuminated exit signs important in a building?

Accepted Answer

They guide people during evacuations

Answer

Illuminated exit signs are critical safety features that clearly mark the path to emergency exits, especially during power outages or in smoke-filled conditions. They provide continuous visual guidance, helping occupants quickly and safely navigate out of a building during an evacuation. Their visibility is essential for efficient egress.
