Where must a spot type heat and smoke sensors be located on walls and ceilings? -
ANSWER ✓ On the ceiling- not less than 4 inches from the sidewall.
On the wall- between 4 inches and 12 inches from the ceiling.
When more than one detector is used on a ceiling, what spacing measurement
shall be used? - ANSWER ✓ All points shall have a detector equal to 0.7 times the
listed spacing.
When water flow occurs that is equal or greater than the flow of a single sprinkler,
how quickly shall the alarm signal initiate? - ANSWER ✓ Within 90 seconds
Can detectors be installed within an air duct system? Can they be used as a
substitute for open area protection? - ANSWER ✓ Yes and No
Detectors shall be ________ for the purpose for which they are being used. -
ANSWER ✓ Listed (i.e zone listed)
Which signals must take priority over all other signals? - ANSWER ✓ Fire. Even
if a non fire signal is generated first.
How many fire alarm boxes (pull stations) are required in systems employing
automatic fire or water flow detectors? - ANSWER ✓ At least one, located where
required by the authority having jurisdiction.
,Systems that require two automatic detectors to initiate the alarm may only be
used after which 3 conditions are filled? - ANSWER ✓ The systems are not
prohibited by the AHJ.
At least two automatic detectors are in each protected space.
The alarm verification feature is not used.
The number of water flow switches permitted to be connected to a single initiating
device shall not exceed ________. - ANSWER ✓ 5
What must be monitored for integrity? - ANSWER ✓ the installation wiring
between the fire alarm control unit and the relay or other appliance.
(Horn, Strobe, etc.)
Each elevator lobby, elevator hoist way and elevator machine room detector must
be capable of what? - ANSWER ✓ initiating elevator recall.
Must the alarm devices within the elevator hoist way be integrated with the fire
alarm? - ANSWER ✓ Yes
Wall mounted appliances must be located between which two distances above a
finished floor? - ANSWER ✓ Not less than 80 inches and not greater than 96
inches above the finished floor.
When may the manual testing frequency be extended to annually? - ANSWER ✓
if automatic testing is performed at least weekly.
The responsibility for inspections, tests, and maintenance programs shall be
assigned by the _______ to a designated person of authority. - ANSWER ✓
Owner
Room sizes and contours, airflow patterns, obstructions, and other characteristics
of the _______ shall be taken into account. - ANSWER ✓ Protected Hazard
Circuits for transmission of supervisory signals shall ____ alarm circuits. -
ANSWER ✓ Ran separate from
, Household smoke alarm and smoke detectors installed within a _______
horizontal path of a cooking appliance shall be equipped with an alarm-silencing
means or be of the photo electric type. - ANSWER ✓ 20 feet
Each household heat detector, including a heat detector integrally mounted on a
smoke detector, shall detect abnormally high temperature or rate-of-temperature
rise and all detector shall be listed or approved for not less than ______ feet
between detectors. - ANSWER ✓ 50 feet
In a combination system, a _____ signal shall take precedence or bo clearly
recognizable over any other signal. - ANSWER ✓ Fire alarm
One of the most critical factors of any fire alarm system is the _____ the fire
detecting devices. - ANSWER ✓ Location of
A circuit or path connecting a subsidiary station to a supervising station over
which signals are carried is called a _______. - ANSWER ✓ Communications
channel
If batteries are used a source of energy, they shall be replaced ________. -
ANSWER ✓ As recommended
What is a ionization smoke detector? - ANSWER ✓ A detector that uses a small
amount of radioactive material to ionize the air between two differently charge
electrodes. When smoke is present between these electrodes, it causes the
conductance of the air to decrease, and this causes the alarm to trip.
What is a photoelectric light scattering smoke detection? - ANSWER ✓ A
detector that uses light source and a photosensitive sensor, arranged so that light
will only fall on the sensor when smoke particles are present. The particles reflect
and retract light towards the sensor tripping the alarm.
What is important about the way trouble signals sound? - ANSWER ✓ They must
be distinctive from alarm signals.
What three procedures must be in place before it is permitted to install a means to
silence trouble/supervisory/alarm signals? - ANSWER ✓ 1. The means shall be
key operated and contained within the locked enclosure.
