Question 1

A projected beam smoke detector is best suited for which type of environment?

Accepted Answer

Large open spaces such as atriums and warehouses

Answer

Projected beam smoke detectors use an infrared beam across large open areas, making them ideal for spaces where ceiling-mounted point detectors would be impractical.

Question 2

When a fire alarm control panel is placed in 'alarm silence' mode, which of the following continues to operate?

Accepted Answer

Strobe notification appliances

Answer

Alarm silence stops audible devices but strobe lights and other visible notification appliances typically continue to operate until the system is fully reset.

Question 3

Which factor is MOST critical when determining the placement of manual pull stations?

Accepted Answer

Location at exits and paths of egress

Answer

Manual pull stations must be placed at exits and along paths of egress so occupants can activate them while evacuating the building.

Question 4

What does NFPA 72 specify as the mounting height range for manual pull stations?

Accepted Answer

42 to 48 inches above finished floor

Answer

NFPA 72 requires manual pull stations to be mounted with the operable part between 42 and 48 inches above the finished floor for accessibility.

Question 5

A fire alarm system using a digital alarm communicator transmitter (DACT) must be connected to how many separate telephone lines?

NFPA 72 requires a DACT to be connected to two separate telephone lines so that if one line is busy or fails, the second provides a backup communication path.
