1. What is the primary purpose of a pre-engineered kitchen hood
fire suppression system?
a. Cooling the cooking area
b. Controlling smoke movement
c. Protecting cooking appliances and exhaust systems from fire
d. Reducing kitchen ventilation requirements
c
Pre-engineered hood systems are designed specifically to detect
and suppress fires in cooking appliances and ducts.
2. Which extinguishing agent is most commonly used in Ansul R-102
systems?
a. Dry chemical
b. Water mist
c. Potassium carbonate solution
d. CO₂
c
, Ansul R-102 systems use a potassium-based wet chemical to
suppress grease fires.
3. The Ansul R-102 system suppresses fire primarily by:
a. Cooling and smothering
b. Displacing oxygen
c. Interrupting the chemical chain reaction
d. Absorbing radiant heat
a
The wet chemical forms a soapy foam layer that cools and
smothers burning grease.
4. How often must a pre-engineered kitchen hood system be
inspected per NFPA 17A?
a. Monthly
b. Every 3 months
c. Every 6 months
d. Annually
c
Semiannual inspections are required for wet chemical
suppression systems.
5. Which component initiates system operation when a fire is
detected?
a. Agent tank
b. Appliance nozzles
c. Detection line and fusible links
d. Pressure switch
c
Heat-responsive links activate the system when they melt.
, 6. Fusible links in a hood system must be replaced:
a. Every year
b. Every inspection
c. Every 6 months
d. Every 3 years
c
NFPA requirements mandate replacement of fusible links every 6
months.
7. What does the term “overlapping appliance protection” refer to?
a. A system protecting two kitchens
b. A nozzle that covers multiple appliances without alignment to
each
c. A backup system for redundancy
d. A secondary agent tank
b
Overlapping protection covers appliance areas rather than exact
appliance footprints.
8. What must occur when the fire suppression system activates?
a. The ventilation system increases airflow
b. The gas and electric power to appliances must shut off
c. Water supply is automatically turned on
d. A kitchen evacuation alarm is triggered
b
Fuel shutoff prevents reignition after suppression.
9. Which device ensures the agent discharges correctly through the
piping?
a. Pressure switch
