1. Which type of alarm system is designed to notify a monitoring
center when triggered?
A. Local alarm
B. Central station alarm
C. Audible-only alarm
D. Passive alarm
Answer: B
Rationale: Central station alarms transmit signals to a monitoring
center for response, unlike local alarms that only alert onsite.
2. What is the primary purpose of a control panel in an alarm
system?
A. To detect motion
B. To sound alarms
C. To serve as the central processing unit for the system
D. To provide power backup
Answer: C
Rationale: The control panel receives inputs from sensors,
, processes them, and triggers outputs such as alarms or
notifications.
3. Which type of sensor detects unauthorized entry through doors
or windows?
A. Smoke detector
B. Heat detector
C. Contact (magnetic) sensor
D. Motion sensor
Answer: C
Rationale: Contact sensors consist of a magnet and switch that
trigger when a door or window is opened.
4. Which frequency band is commonly used for wireless alarm
sensors?
A. 1 GHz
B. 5 GHz
C. 300–400 MHz
D. 900–1000 MHz
Answer: C
Rationale: Most wireless security sensors operate in the 300–400
MHz range, offering reliable communication without interfering
with Wi-Fi.
5. What is the function of a siren in an alarm system?
A. To communicate with central monitoring
B. To detect intruders
C. To provide audible alert to occupants and neighbors
D. To power sensors
Answer: C
Rationale: Sirens alert people nearby to a breach, serving as both
a deterrent and notification device.
,6. Which component ensures an alarm system operates during a
power outage?
A. Siren
B. Battery backup
C. Control panel
D. Motion sensor
Answer: B
Rationale: Battery backups maintain system operation if main
power fails.
7. Which type of motion detector is most effective in complete
darkness?
A. Ultrasonic
B. Microwave
C. Passive infrared (PIR)
D. Dual-technology
Answer: C
Rationale: PIR detectors sense body heat, functioning without
visible light.
8. What is the typical maximum distance between a wireless sensor
and its receiver?
A. 10 ft
B. 50 ft
C. 300 ft (line of sight)
D. 1 mile
Answer: C
Rationale: Most wireless alarm systems are designed to work
reliably up to 300 feet in open space.
9. What is the primary purpose of a tamper switch in an alarm
device?
, A. To trigger the siren
B. To detect unauthorized opening or removal of the device
C. To backup power
D. To reset the system
Answer: B
Rationale: Tamper switches alert the control panel if a device is
physically tampered with.
10. Which wire type is typically used for alarm system
installations?
A. Coaxial cable
B. CAT5e only
C. Fiber optic
D. 18–22 gauge stranded or solid wire
Answer: D
Rationale: 18–22 gauge wiring is standard for most low-voltage
alarm system circuits.
11. What is the main purpose of a keypad in an alarm system?
A. To detect fire
B. To monitor sensors
C. To arm and disarm the system
D. To transmit signals
Answer: C
Rationale: Keypads allow authorized users to input codes to
control the system.
12. What does “end-of-line resistor” do in a wired alarm circuit?
A. Powers the sensor
B. Triggers the siren
C. Monitors circuit integrity
D. Transmits wireless signals
