1. Which Colorado agency has primary responsibility for regulating
private security services and security professionals under Colorado
law?
A. Colorado Department of Transportation
B. Colorado Department of Labor and Employment
C. Colorado Department of Regulatory Agencies
D. Colorado Department of Agriculture
Answer: C. Colorado Department of Regulatory Agencies
Rationale: The Colorado Department of Regulatory Agencies (DORA)
administers and oversees numerous professional and occupational
regulatory programs in Colorado, including applicable regulation of
private security services and related professionals.
2. When installing a security system in Colorado, which requirement
should a contractor verify before beginning work on a commercial
building?
,A. The owner's preferred alarm sound
B. Applicable building, electrical, fire, and local code requirements
C. The manufacturer's advertising specifications only
D. The customer's insurance deductible
Answer: B. Applicable building, electrical, fire, and local code
requirements
Rationale: Security-system installations can involve electrical wiring, life-
safety interfaces, building penetrations, and fire alarm connections, so
the contractor must determine which applicable codes and local
requirements govern the project.
3. What is the primary purpose of an intrusion detection system?
A. To regulate building temperature
B. To detect unauthorized entry or movement and generate an
appropriate signal
C. To provide emergency lighting
D. To replace the building's electrical service
Answer: B. To detect unauthorized entry or movement and generate an
appropriate signal
Rationale: An intrusion detection system uses sensors, control
equipment, communication pathways, and notification devices to
identify conditions associated with unauthorized access or movement.
4. Which device is commonly used to detect the opening of a
protected door or window?
,A. Magnetic contact
B. Smoke detector
C. Thermostat
D. Current transformer
Answer: A. Magnetic contact
Rationale: A magnetic contact consists of a switch and magnet that
monitor the position of a door or window and change electrical state
when the protected opening is opened.
5. In a conventional alarm circuit, what is the primary purpose of an
end-of-line resistor?
A. Increase speaker volume
B. Monitor circuit integrity and help detect certain wiring faults
C. Convert AC power to DC power
D. Increase battery capacity
Answer: B. Monitor circuit integrity and help detect certain wiring faults
Rationale: An end-of-line resistor establishes a supervised electrical
condition that allows the control panel to distinguish normal circuit
conditions from conditions such as an open circuit or, where designed, a
short circuit.
6. A security system's standby battery is rated at 7 ampere-hours. If a
connected load continuously draws 0.5 ampere under ideal
conditions, approximately how long would the battery theoretically
supply the load?
, A. 3.5 hours
B. 7 hours
C. 14 hours
D. 28 hours
Answer: C. 14 hours
Rationale: The theoretical operating time is calculated by dividing
ampere-hours by load current: 7 Ah ÷ 0.5 A = 14 hours. Actual operating
time is generally lower because of battery characteristics, temperature,
age, and discharge conditions.
7. Which component is normally considered the central processing
unit of an intrusion alarm system?
A. Door strike
B. Control panel
C. Passive infrared detector
D. Exterior siren
Answer: B. Control panel
Rationale: The control panel receives signals from initiating devices,
processes those signals according to programmed parameters, controls
notification and other outputs, and communicates system conditions as
designed.
8. What is the principal function of a passive infrared detector?
A. Detect changes in infrared radiation associated with movement
B. Detect water pressure
