Sample NICET Fire Alarm Systems questions

System Components & Devices

What is the primary purpose of a manual pull station in a fire alarm system?

  1. A. To automatically detect heat and activate the alarm
  2. B. To allow occupants to manually initiate a fire alarm signal
  3. C. To reset the fire alarm control panel after an alarm
  4. D. To monitor the integrity of the notification appliance circuit

Answer: B. Manual pull stations are initiating devices that allow building occupants to manually trigger a fire alarm signal when they discover a fire or emergency condition. They do not automatically detect fire — that function is performed by automatic detectors.

NFPA 72 Code Requirements

According to NFPA 72, what is the minimum candela rating required for a visible notification appliance (strobe) located in a corridor that is no more than 20 feet wide?

  1. A. 15 candela
  2. B. 30 candela
  3. C. 75 candela
  4. D. 110 candela

Answer: A. NFPA 72 Table 18.5.5.4.1(a) specifies that in corridors up to 20 feet wide, a single strobe placed at the midpoint can use a 15-candela rating. Higher candela ratings are required for wider areas or when strobes are placed at greater distances from occupants.

Wiring & Installation

What is the key operational difference between a Class A and Class B initiating device circuit (IDC)?

  1. A. Class A operates at higher voltage; Class B operates at lower voltage
  2. B. Class A uses two separate paths so the circuit continues to function with a single open fault; Class B does not
  3. C. Class A supports addressable devices only; Class B supports conventional devices only
  4. D. Class A requires end-of-line resistors; Class B does not

Answer: B. Class A wiring (also called Style D) uses a loop configuration with separate supply and return conductors, so a single open-circuit fault will not prevent devices from operating — the panel can still communicate with all devices via the alternate path. Class B (Style B) uses a single path with an end-of-line resistor; a single open fault will disable all devices beyond the break.
