1. What is the primary purpose of an intrusion alarm system?
A. To provide entertainment
B. To detect unauthorized entry or activity and generate an alarm condition
C. To replace all physical locks
D. To eliminate the need for security personnel
Answer: To detect unauthorized entry or activity and generate an alarm
condition
Rationale: An intrusion alarm system is designed to detect defined security
events and notify occupants, monitoring personnel, or other authorized
responders.
2. What device is commonly used to detect the opening of a protected door
or window?
A. Smoke detector
B. PIR detector
C. Magnetic contact
D. Glass-break detector
Answer: Magnetic contact
,Rationale: A magnetic contact detects separation between a magnet and switch
when a door or window is opened.
3. What does PIR stand for in security systems?
A. Primary Intrusion Relay
B. Passive Infrared
C. Power Input Resistor
D. Programmable Intrusion Receiver
Answer: Passive Infrared
Rationale: A PIR detector senses changes in infrared energy, commonly caused
by movement within its detection area.
4. Which device is specifically designed to detect the sound or vibration
associated with breaking glass?
A. Magnetic contact
B. Glass-break detector
C. Smoke detector
D. Heat detector
Answer: Glass-break detector
Rationale: Glass-break detectors are designed to recognize acoustic or other
characteristics associated with breaking glass.
5. What is the main purpose of an alarm control panel?
A. To physically lock every door
B. To process signals from field devices and control alarm-system functions
C. To provide telephone service
D. To replace all system sensors
Answer: To process signals from field devices and control alarm-system
functions
,Rationale: The control panel is the central processing component that supervises
zones, receives detector signals, operates outputs, and manages system status.
6. What is a security system zone?
A. A type of battery
B. A defined input or group of inputs monitored by the control panel
C. A type of siren
D. A programming password
Answer: A defined input or group of inputs monitored by the control panel
Rationale: Zones allow the control panel to identify and supervise individual
circuits or groups of detection devices.
7. What is the purpose of an end-of-line resistor in a supervised alarm circuit?
A. To increase speaker volume
B. To help the panel supervise the circuit for abnormal conditions
C. To charge the backup battery
D. To increase AC voltage
Answer: To help the panel supervise the circuit for abnormal conditions
Rationale: An end-of-line resistor allows the panel to distinguish normal circuit
conditions from certain open- or short-circuit conditions, depending on system
design.
8. What does “normally closed” mean for a switch?
A. The contacts are open when the switch is in its normal state
B. The contacts are closed when the switch is in its normal state
C. The switch has no electrical connection
D. The switch operates only on AC power
Answer: The contacts are closed when the switch is in its normal state
, Rationale: A normally closed contact maintains continuity in its normal condition
and opens when actuated or otherwise changed.
9. What is the purpose of a backup battery in an alarm system?
A. To increase sensor sensitivity
B. To operate the system during loss of primary power
C. To replace all wiring
D. To eliminate grounding requirements
Answer: To operate the system during loss of primary power
Rationale: The standby battery helps maintain alarm-system operation when the
normal AC or primary power source is unavailable.
10.Which instrument is most appropriate for measuring electrical voltage?
A. Tape measure
B. Multimeter
C. Level
D. Crimping tool
Answer: Multimeter
Rationale: A properly configured multimeter can measure voltage and,
depending on the instrument, resistance, current, and continuity.
11.What should an installer do before working on energized electrical
equipment?
A. Assume the circuit is safe
B. Follow applicable lockout/tagout and electrical safety procedures
C. Touch the conductors together
D. Remove the equipment grounding conductor
Answer: Follow applicable lockout/tagout and electrical safety procedures
