These 10 free NICET questions are organized by exam domain, so you can see how each part of the NICET Fire Alarm Systems (FAS) Certification blueprint is tested. Reveal the answer and explanation under each question.

Domain 1: Level I: Fundamentals, Installation, Initiating Devices and Notification Appliances

Question 1

A fire alarm technician discovers an end-of-line resistor taped to the back of the fire alarm panel instead of installed at the last device on the circuit. This means:

  1. The circuit is properly supervised and will detect faults normally
  2. The circuit is not properly supervised because the wiring beyond the panel is unmonitored
  3. The EOLR is in an acceptable alternate location per the installation code
  4. The circuit is configured as Class A and does not require an EOLR
Show answer & explanation

Correct answer: B - The circuit is not properly supervised because the wiring beyond the panel is unmonitored

Domain 2: Level II: Circuits, Power Calculations, Codes, Occupancy and Work Planning

Question 2

A fire alarm system has the following: Standby current = 0.5A, Alarm current = 3.0A. System type: General (5-minute alarm). What is the required battery capacity with 20% safety factor?

  1. 12.0 AH
  2. 12.3 AH
  3. 14.7 AH
  4. 15.0 AH
Show answer & explanation

Correct answer: C - 14.7 AH

Question 3

A technician installs a fire alarm cable that runs from a general-purpose area, through a riser shaft, and then into a plenum space. What cable rating must be used for the ENTIRE run?

  1. FPL rated cable because the general-purpose area determines the minimum cable type
  2. FPLR rated cable because the riser shaft section determines the minimum cable type
  3. FPLP rated cable because the most restrictive area determines the rating for the entire run
  4. Different cable types can be spliced together at each transition point between areas
Show answer & explanation

Correct answer: C - FPLP rated cable because the most restrictive area determines the rating for the entire run

Question 4

A smoke detector sensitivity test reveals that a detector is reading outside its listed and marked sensitivity range. What is the FIRST required action?

  1. Immediately replace the detector
  2. Clean the detector and retest it
  3. Adjust the panel sensitivity settings for that zone
  4. Document the reading and schedule a follow-up test in 30 days
Show answer & explanation

Correct answer: B - Clean the detector and retest it

Domain 3: Level III: System Design, Commissioning, Periodic Testing and Project Supervision

Question 5

A Level III technician discovers that a Level I technician has been installing spot-type smoke detectors on a ceiling with exposed beams that are 20 inches deep and spaced 10 feet on center. The technician installed detectors as though the ceiling were smooth. What correction is required?

  1. No correction needed because the beam spacing and depth are within code allowances
  2. Each bay must be treated as a separate room since the beams exceed 18 inches in depth
  3. Detectors must be relocated to the bottom of each beam
  4. Add additional detectors between the existing ones at half the listed spacing
Show answer & explanation

Correct answer: B - Each bay must be treated as a separate room since the beams exceed 18 inches in depth

Question 6

A room measures 35 feet × 35 feet. This room falls between the 28×28 and 40×40 entries in NFPA 72 Table 18.5.5.5.1(a). The Level III technician should select:

  1. 15 cd since the room dimensions are closer to the 28×28 table entry
  2. 30 cd based on linear interpolation between the two table entries
  3. 60 cd since you must round up to the next larger room size in the table
  4. 45 cd calculated as the average of the 30 cd and 60 cd table values
Show answer & explanation

Correct answer: C - 60 cd since you must round up to the next larger room size in the table

Question 7

Audible notification appliances in sleeping areas must use what type of signal?

  1. A standard 3-120 Hz temporal pattern horn signal
  2. A high-frequency signal above 2000 Hz
  3. A 520 Hz low-frequency square wave or equivalent signal
  4. Any audible signal that meets the 75 dBA requirement
Show answer & explanation

Correct answer: C - A 520 Hz low-frequency square wave or equivalent signal

Domain 4: Level IV: Advanced Design, Integrated Systems, Operations and Business Management

Question 8

A fire alarm company receives a change order request from a general contractor to add 15 notification appliances to an already-contracted project. Before executing the change order, the Level IV technician should FIRST:

  1. Evaluate the impact on battery calculations, voltage drop, and circuit loading
  2. Decline the change order because it was not in the original contract
  3. Forward the request to the insurance carrier for approval
  4. Install the appliances and invoice for time and materials
Show answer & explanation

Correct answer: A - Evaluate the impact on battery calculations, voltage drop, and circuit loading

Question 9

When approving shop drawings, the Level IV technician discovers that the battery calculation shows a required capacity of 22.5 AH, but the designer has specified an 18 AH battery. The CORRECT action is to:

  1. Approve the drawing with a note to retest battery capacity in 6 months
  2. Approve the drawing since the specified battery capacity is close enough
  3. Require two 12 AH batteries wired in series to meet the 22.5 AH requirement
  4. Reject the specification and require the next available battery size above 22.5 AH
Show answer & explanation

Correct answer: D - Reject the specification and require the next available battery size above 22.5 AH

Question 10

During shop drawing review, the Level IV technician notices that voltage drop calculations show 4.2V drop on a NAC circuit. The panel output at end-of-battery life is 20.4 VDC and the minimum appliance operating voltage is 16 VDC. This design:

  1. Fails because a 4.2V voltage drop exceeds the standard 3V design limit
  2. Fails because the voltage drop exceeds the maximum allowable percentage
  3. Requires additional wire gauge data before the design can be evaluated
  4. Passes because the end voltage of 16.2V is above the 16V minimum
Show answer & explanation

Correct answer: D - Passes because the end voltage of 16.2V is above the 16V minimum
