1. Which statement best describes the primary purpose of an electronic
security system technician's role when designing, installing,
commissioning, and maintaining security equipment in a commercial
facility?
A. To replace all mechanical security measures with electronic devices
regardless of risk
B. To ensure security technologies are correctly selected, installed,
integrated, tested, documented, and maintained according to the facility's
security objectives
C. To configure every security device using identical programming regardless
of manufacturer
D. To focus exclusively on repairing failed devices after an alarm occurs
,Answer: B
The technician's responsibility extends across system selection, installation,
configuration, testing, integration, documentation, and maintenance so
that the electronic security system performs its intended protective
function.
2. During an initial security assessment of a facility, which factor should
receive the greatest consideration when determining the appropriate
electronic security measures?
A. The technician's preferred equipment manufacturer
B. The color and appearance of the security equipment
C. Identified threats, vulnerabilities, assets, operational requirements, and
consequences of security incidents
D. The number of devices installed at neighboring facilities
Answer: C
A security system should be risk-based, meaning threats, vulnerabilities,
protected assets, operational requirements, and potential consequences
guide the selection and design of protective measures.
3. Which electrical characteristic is measured in volts and represents the
electrical potential difference between two points?
,A. Current
B. Resistance
C. Voltage
D. Power factor
Answer: C
Voltage is the electrical potential difference between two points and is
measured in volts, while current is measured in amperes and resistance in
ohms.
4. An electronic security technician measures the current flowing
through a circuit. Which unit should appear on the meter display?
A. Ohms
B. Amperes
C. Volts
D. Watts
Answer: B
Electrical current is measured in amperes, commonly abbreviated as amps
or A, and indicates the rate at which electric charge flows through a circuit.
5. According to Ohm's law, which relationship correctly represents the
voltage across a resistive load?
, A. V = I × R
B. V = I ÷ R
C. V = R ÷ I
D. V = I + R
Answer: A
Ohm's law states that voltage equals current multiplied by resistance,
expressed as V = I × R.
6. A 12-volt security device draws 0.5 amperes under normal operating
conditions. Approximately how much electrical power does the device
consume?
A. 6 watts
B. 12 watts
C. 24 watts
D. 0.04 watts
Answer: A
Electrical power can be calculated using P = V × I, so 12 volts multiplied by
0.5 amperes equals 6 watts.
7. Why is proper grounding particularly important in electronic security
installations?
