1. What is the primary purpose of an intrusion detection system
(IDS) in a security installation?
a. To provide decorative lighting
b. To regulate building temperature
c. To detect unauthorized entry or activity
d. To control water pressure
Rationale: An intrusion detection system is designed to identify
unauthorized access or suspicious activity and generate an alarm or
notification. It may use sensors such as door contacts, motion
detectors, glass-break detectors, and other devices.
2. Which device is commonly used to detect the opening of a door
or window?
,a. Smoke detector
b. Heat detector
c. Magnetic contact
d. Photoelectric sensor
Rationale: A magnetic contact consists of a magnet and a switch.
When the protected door or window opens, the magnet separates
from the switch and changes the circuit state, allowing the security
system to recognize the opening.
3. What is the main function of an alarm control panel?
a. To supply municipal water
b. To paint the building
c. To receive, process, and respond to signals from security devices
d. To measure electrical consumption only
Rationale: The control panel is the central processing unit of an alarm
system. It monitors connected sensors, interprets their signals,
activates alarms when appropriate, and may communicate events to
a monitoring station.
4. Which type of detector is designed to identify movement by
sensing changes in infrared radiation?
,a. Magnetic contact
b. Passive infrared detector
c. Water-flow switch
d. Tamper resistor
Rationale: Passive infrared (PIR) detectors sense changes in infrared
energy caused by moving objects, particularly people. They are widely
used for interior motion detection.
5. What is the purpose of an end-of-line resistor in many security
circuits?
a. To increase alarm volume
b. To provide emergency lighting
c. To supervise the circuit for conditions such as open or shorted
wiring
d. To convert AC power into mechanical energy
Rationale: An end-of-line resistor allows the control panel to supervise
the integrity of a circuit. Depending on the system design, the panel
can distinguish normal, alarm, open, and sometimes short-circuit
conditions.
6. Which component provides backup electrical power when the
primary power source fails?
, a. Motion detector
b. Keypad
c. Standby battery
d. Door contact
Rationale: Security systems commonly use rechargeable standby
batteries so that essential equipment can continue operating during a
commercial power interruption.
7. What is the purpose of a security system keypad?
a. To increase cable diameter
b. To allow authorized users to operate and program system functions
c. To detect smoke
d. To ground the building
Rationale: A keypad provides a user interface for arming and
disarming the system, entering access codes, reviewing events, and,
where authorized, performing programming functions.
8. Which security device is specifically intended to detect the
breaking of glass?
a. Heat detector
b. Magnetic lock
