NICET In-Building Public Safety Communications
(IB-PSC) Technician Level II Exam ACTUAL
QUESTIONS AND ANSWERS LATEST UPDATE
THIS YEAR
About the NICET IB-PSC Level II Exam
The Level II certification is designed for technicians with at least 2 years of
experience who, under limited supervision, conduct surveys, install, commission,
and maintain in-building public safety communications systems . The exam covers:
| Domain | Weight |
|||
| Defining the Project Scope | 15–25% |
| Evaluating RF Signal Strength and Quality | 20–30% |
| Performing Rough Installation Activities | — |
| Finish and Trim Out Installation | 10–20% |
| Commissioning, Acceptance Test, and Maintenance | 20–30% |
Exam Format: 143 questions, time limit varies by level, scaled passing score of
500 (500+ reported as Pass) . Allowed references include IFC 2018, NFPA 70
2020, and NFPA 1221 2019 .

,Practice Questions
1. A building owner requests an ERCES system that uses fiber optic cable from the
headend to remote units on each floor. What is the primary advantage of fiber over
coaxial cable for this application?
- A) Fiber is less expensive than copper coaxial cable
- B) Fiber is easier to terminate in the field
- C) Fiber has much lower signal loss over long distances
- D) Fiber can carry power to remote amplifiers
Correct Answer: C. Fiber optic cable has very low attenuation over long
distances, making it ideal for distributing signals in large or high-rise buildings .
2. What is the basic purpose of a donor antenna in an ERCES?
- A) Receive and transmit between the building system and the outside public-
safety radio system
- B) Measure battery temperature inside the BDA cabinet
- C) Replace all interior service antennas
- D) Silence BDA trouble alarms during acceptance testing
Correct Answer: A. The donor antenna is the outside-facing antenna that
couples the ERCES to the licensed public-safety radio system .
2
,3. In an ERCES, what does the downlink path generally describe?
- A) Signals traveling from the public-safety radio system toward portable radios
inside the building
- B) Signals traveling from interior portable radios back toward the public-safety
receiver
- C) The fire alarm SLC returning to the panel
- D) The battery charger output to the batteries
Correct Answer: A. Downlink refers to the path from the outside radio system
through the ERCES to emergency responders inside the building .
4. What does a bidirectional amplifier (BDA) do in a typical ERCES?
- A) Amplifies radio paths between the public-safety system and in-building
antennas
- B) Converts all fire alarm signals into text messages
- C) Stores the official inspection report for the AHJ
- D) Provides sprinkler waterflow supervision
Correct Answer: A. A BDA amplifies radio signals in both the downlink and
uplink directions when designed and authorized for public-safety frequencies .
5. Which group contains only common passive DAS distribution components?
- A) Splitters, directional couplers, coaxial cable, and service antennas
- B) Batteries, chargers, AC disconnects, and transfer switches
3
, - C) Smoke detectors, pull stations, horn strobes, and control modules
- D) Servers, keyboards, printers, and office routers
Correct Answer: A. Passive DAS components route RF energy without
powered amplification. Splitters, couplers, coax, and antennas are common
examples .
6. In a DAS, what is the function of the bi-directional amplifier (BDA)?
- A) To block unwanted signals from entering the system
- B) To convert digital signals to analog
- C) To amplify both transmitted and received signals between the radio system
and in-building antennas
- D) To provide power backup for antennas
Correct Answer: C. BDAs boost both incoming and outgoing signals for
reliable two-way communication .
7. NICET's IB-PSC program page says the updated exams replaced older NFPA
1221 references with which standard edition?
- A) NFPA 13 (2022)
- B) NFPA 72 (2019)
- C) NFPA 1225 (2022)
- D) NFPA 101 (2021)
