1. What is the primary purpose of a security system installed in a
commercial building?
A. To increase electrical consumption
B. To replace all building personnel
C. To detect, deter, and report unauthorized activity or security
threats
D. To eliminate the need for emergency planning
Answer: C
Rationale: A security system is designed to provide protection by
detecting unauthorized entry, suspicious activity, or other defined
threats and communicating that information to responsible personnel.
,It supplements, rather than automatically replaces, physical security
measures and established emergency procedures.
2. Which device is commonly used to detect when a protected door is
opened?
A. Smoke detector
B. Magnetic contact
C. Thermostat
D. Photocell
Answer: B
Rationale: A magnetic contact consists of a switch and magnet
installed so that opening the door separates them and changes the
electrical state of the circuit. This change can be detected by the
security control panel as an opening or alarm condition.
3. What is the primary function of a security control panel?
A. Provide mechanical ventilation
B. Regulate building temperature
C. Receive, process, and communicate signals from security devices
D. Supply water to fire sprinklers
,Answer: C
Rationale: The control panel serves as the central processing unit of
many security systems. It receives signals from sensors, evaluates
programmed conditions, activates appropriate outputs, and may
communicate alarm or trouble information to a monitoring facility.
4. Which sensor is most commonly associated with detecting motion
inside a protected area?
A. Doorbell transformer
B. Magnetic lock
C. Passive infrared detector
D. Surge protector
Answer: C
Rationale: A passive infrared (PIR) detector senses changes in infrared
energy within its field of view. Movement by a person across the
detector's zones can produce a change that the device interprets as
motion.
5. What is the purpose of an end-of-line resistor in a supervised
security circuit?
, A. Increase speaker volume
B. Convert AC power to DC power
C. Allow the control panel to supervise the circuit for certain wiring
faults
D. Increase the physical strength of the cable
Answer: C
Rationale: An end-of-line resistor establishes a known electrical
condition at the end of a supervised circuit. The control panel can
compare the measured condition with expected values and identify
conditions such as an open or, depending on circuit design, a short.
6. Which power source is commonly used as standby power for a
security control panel?
A. Gas generator only
B. Rechargeable battery
C. Solar panel only
D. Capacitor only
Answer: B
Rationale: Rechargeable batteries are commonly incorporated into
security systems so that essential equipment can continue operating
