1. What is the primary purpose of an alarm system control panel?
A. To detect motion directly
B. To receive, process, and respond to sensor signals
C. To supply backup lighting
D. To record video footage
The control panel is the brain of the alarm system, interpreting
signals from all connected devices.
2. Which type of sensor detects changes in infrared energy?
A. Magnetic contact
B. Glass break sensor
C. Passive infrared (PIR) sensor
D. Pressure mat
PIR sensors respond to body heat and infrared radiation changes.
3. What does EOL stand for in alarm wiring?
A. End of line
B. Emergency override loop
C. End-of-line resistor
D. External output lead
End-of-line resistors supervise wiring integrity.
,4. Which voltage is most commonly used by alarm system control
panels?
A. 120 VAC
B. 48 VDC
C. 12 VDC
D. 5 VDC
Most intrusion alarm panels operate on 12-volt DC systems.
5. What is the main function of a magnetic contact switch?
A. Detect vibration
B. Detect heat
C. Detect opening or closing of doors and windows
D. Detect sound waves
Magnetic contacts separate when a protected opening is
breached.
6. Which alarm system component provides backup power during
outages?
A. Transformer
B. Surge protector
C. Battery
D. Relay
Backup batteries ensure continued operation during power loss.
7. What type of cable is most commonly used for hardwired alarm
sensors?
A. Coaxial
B. Fiber optic
C. 22/4 or 22/2 stranded security cable
, D. Cat 6
Security cable is designed for low-voltage alarm circuits.
8. What is the purpose of a tamper switch?
A. Improve sensitivity
B. Silence alarms
C. Detect unauthorized opening of equipment enclosures
D. Adjust voltage
Tamper switches trigger alarms if devices are opened or removed.
9. Which device converts AC power to DC power for alarm systems?
A. Relay
B. Rectifier
C. Transformer and power supply
D. Resistor
The power supply steps down and converts power appropriately.
10. What is a normally closed (NC) circuit?
A. Open until activated
B. Closed during normal operation
C. Used only in wireless systems
D. Illegal in alarm systems
NC circuits open during faults, making them easier to supervise.
11. Which sensor is best suited for detecting breaking glass?
A. PIR
B. Magnetic contact
C. Acoustic glass break sensor
D. Smoke detector
Glass break sensors detect specific sound frequencies.
