NICET Level 2 Questions & Answers
1. Consider a room which is 40' square. How many 15cd wall mounted strobes
are required to adequately cover this space?
Answer 4
2. What is the testing frequency of a strobe?
Answer Annually
3. In a corridor application, visible appliances shall be rated not less than
cd?
Answer 15
4. Consider a household fire alarm
system where the primary power is provided by a circuit that can be switched off
by means other than a circuit breaker. The battery must be recharged in
Answer 4 hours
5. Where automatic drift compensation of detectors is provided
Answer
The control unit shall identify the attected detector when the compensation limit has been reached.
6. A fire alarm system requires the use of smoke detectors in a corridor. The
corridor is 10' wide and 120' long. The ceiling of the corridor is smooth and

, flat and 10' high. What is the minimum number of smoke detectors in the
corridor.
Answer 3
7. The fire alarm system design for a room called for smoke
detector spacing based on a smooth flat ceiling. Upon inspecting the room, it is
determined that the ceiling has beams. The beam spacing is less than 40% of the
ceiling height. NFPA72 permits smooth ceiling spacing in the direction parallel
to the beams and spacing in the direction perpendicular to the beams.
Answer One half smooth ceiling

8. The working drawings for a fire alarm system show that 2 duct detectors are
required. The building is a single story with 4 HVAC units (1-5,000 cfm, 1-4000
cfm, 1-3000 cfm, 1-2000 cfm) How many duct detectors are required?
Answer 3
9. The fire alarm
system for a building requires the use of audible notification appliances for
public mode notification. To ensure public mode signals are clearly heard, they
shall have a sound level of at least db above the
average ambient sound level?
