Rationale: Heat detectors activate when a certain temperature or

rate of rise is reached, unlike smoke detectors.

• What NFPA standard governs the installation of fire alarm systems?

A. NFPA 13

B. NFPA 72 **

C. NFPA 101

D. NFPA 70

Rationale: NFPA 72 is the National Fire Alarm and Signaling Code,

which outlines installation and maintenance standards.

• Remote station system

Rationale: Conventional systems divide the building into zones, each

wired to a control panel.

• What is the advantage of an addressable fire alarm system?
• Lower installation cost
• Each device has a unique address for precise location identification

**

• No maintenance required
• Uses less wiring than a conventional system

Rationale: Addressable systems allow precise identification of which

detector or device has activated.

• How often should fire alarm systems be tested according to

NFPA 72?

• Monthly for all devices
• Weekly for control panels only
• Annually for all devices **
• Every 5 years
