1. What is the primary purpose of a fire alarm system?
A. To detect and alert occupants of fire
Fire alarm systems are designed to detect fires early and notify
occupants to evacuate safely.
2. How often should a fire alarm system be visually inspected?
B. Weekly to monthly, depending on NFPA requirements
Regular visual inspections help ensure the system appears operational
and no devices are damaged.
3. Which NFPA standard governs the maintenance of fire alarm systems?
C. NFPA 72
NFPA 72 covers inspection, testing, and maintenance of fire alarm
systems.
4. What is a common sign that a smoke detector requires cleaning?
A. Frequent false alarms
Dust or debris can interfere with smoke detection, causing nuisance
alarms.
5. How often should smoke detectors in commercial buildings be cleaned?
B. At least annually
Annual cleaning removes dust and debris that may impair detection.
6. What is the recommended method for testing manual pull stations?
C. Activate the station and verify signal at the control panel
This ensures both the station and panel are functioning correctly.
7. What is the primary reason to perform battery checks in fire alarm
systems?
A. To ensure system reliability during power loss
Batteries provide backup power if main power fails, ensuring continuous
operation.
, 8. How often should batteries in a fire alarm system be replaced if not
sealed lead-acid type?
B. Every 3 years
Regular replacement prevents battery failure and system downtime.
9. Which component of a fire alarm system sends the notification signal?
A. Notification appliances
Notification appliances (horns, strobes) alert occupants of an emergency.
10.During maintenance, why is it important to verify all control panel
indicators?
C. To ensure proper system status and fault monitoring
Indicators show system health, faults, and operational status.
11.What is the first step before performing maintenance on a fire alarm
system?
B. Notify building occupants and/or authorities
Notification prevents unnecessary panic or false fire responses during
maintenance.
12.How often should sprinkler water flow switches be tested?
C. Annually
Testing ensures that water flow triggers the alarm correctly.
13.What is a common cause of false alarms in heat detectors?
A. Exposure to steam or cooking heat
Heat detectors can be activated by high temperatures unrelated to fire.
14.How should a dusty smoke detector be cleaned?
B. Using a vacuum or soft brush
Careful cleaning removes debris without damaging sensitive sensors.
15.What is the typical lifespan of a smoke detector?
C. 10 years
After this period, detectors may fail to respond reliably and should be
replaced.
16.When performing system testing, why should only one device be tested
at a time?
A. To isolate faults and prevent false alarms
Testing devices individually ensures accurate diagnostics.
