  1. In a corridor, wall-mounted strobes must be spaced no more than how many feet apart per NFPA 72?

    Answer: 100 feet

    NFPA 72 requires corridor strobes to be spaced no more than 100 feet apart measured along the corridor to ensure adequate visual coverage.

  2. The first strobe in a corridor must be placed within how many feet of each end of the corridor per NFPA 72?

    Answer: 15 feet

    Per NFPA 72, the first strobe in a corridor must be located within 15 feet of each end to ensure occupants near corridor ends receive visual notification.

  3. What is 'public mode' notification in a fire alarm system?

    Answer: Notification intended to alert all building occupants to take protective action

    Public mode notification is designed to alert all building occupants simultaneously so they can take appropriate protective action such as evacuation.

  4. What is 'private mode' notification in a fire alarm system?

    Answer: Notification directed to responsible personnel rather than all occupants

    Private mode notification is directed to designated personnel (such as security or building staff) rather than all building occupants, allowing trained staff to respond first.

  5. Per NFPA 72, what is the maximum mounting height for a ceiling-mounted strobe?

    Answer: 30 feet

    NFPA 72 permits ceiling-mounted strobes to be installed at a maximum height of 30 feet above the finished floor.

  6. Why does NFPA 72 require a low-frequency sounder at 520 Hz for sleeping area notification?

    Answer: To awaken sleeping occupants more effectively, especially those with mild hearing loss

    Research has shown that low-frequency tones at 520 Hz are significantly more effective at awakening sleeping occupants, particularly those with mild to moderate hearing loss.

  7. A Notification Appliance Circuit (NAC) provides supervised power to which devices?

    Answer: Audible and visual notification appliances

    The Notification Appliance Circuit (NAC) provides supervised power distribution specifically to audible and visual notification devices throughout the protected premises.
