4 -CORRECTANSWER Consider a room which is 40' square. How many 15cd wall
mounted strobes are required to adequately cover this space?
Annually -CORRECTANSWER What is the testing frequency of a strobe?
15 -CORRECTANSWER In a corridor application, visible appliances shall be rated not
less than ________ cd?
4 hours -CORRECTANSWER 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____________
The control unit shall identify the affected detector when the compensation limit has
been reached. -CORRECTANSWER Where automatic drift compensation of detectors
is provided:
3 -CORRECTANSWER 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.
, One half smooth ceiling
NFPA 72 17.7.3.2.4.2(2)bi pg 98 -CORRECTANSWER 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.
3 -CORRECTANSWER 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?
15
NFPA72 18.4.3.1 pg107 -CORRECTANSWER 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?
Location of utilities -CORRECTANSWER Site plans typically include:
Level -CORRECTANSWER A ceiling surface has a slope of 1 in 9. This is considered a
____________ ceiling.
