1. What is the primary purpose of a security system intrusion
detection device?
A. To regulate building temperature
B. To detect unauthorized entry or activity
C. To control water pressure
D. To provide emergency lighting
Answer: B. To detect unauthorized entry or activity
Rationale: Intrusion detection devices are designed to identify
unauthorized access or suspicious activity. Depending on the system,
they may detect opening doors or windows, motion, glass breakage, or
other intrusion-related events.
, 2. Which component is commonly used to detect the opening of a
protected door?
A. Smoke detector
B. Magnetic contact
C. Heat detector
D. Transformer
Answer: B. Magnetic contact
Rationale: A magnetic contact consists of a switch and magnet installed
so that separating the two changes the electrical state of the circuit.
This makes it suitable for detecting the opening of doors, windows, and
similar protected openings.
3. In a typical security system, what is the primary function of the
control panel?
A. Generate building power
B. Process signals and manage system devices
C. Increase network bandwidth
D. Provide mechanical ventilation
Answer: B. Process signals and manage system devices
Rationale: The control panel is the central processing component of
many security systems. It receives signals from sensors, evaluates those
,signals according to programmed rules, activates outputs, and
communicates alarms or other conditions.
4. What type of detector is specifically designed to identify
movement within a protected area?
A. Motion detector
B. Door strike
C. Card reader
D. Relay module
Answer: A. Motion detector
Rationale: Motion detectors monitor a designated area for movement.
Common technologies include passive infrared (PIR), microwave, and
dual-technology detection.
5. What does PIR stand for in security detection equipment?
A. Power Interrupt Relay
B. Passive Infrared
C. Protected Input Resistor
D. Primary Intrusion Response
Answer: B. Passive Infrared
, Rationale: PIR stands for Passive Infrared. PIR detectors sense changes
in infrared energy, typically caused when a person or other warm object
moves across zones within the detector's field of view.
6. What is the main advantage of a dual-technology motion
detector?
A. It eliminates the need for wiring
B. It requires two different detection technologies to confirm certain
alarm conditions
C. It operates without power
D. It automatically replaces the control panel
Answer: B. It requires two different detection technologies to confirm
certain alarm conditions
Rationale: Dual-technology detectors commonly combine technologies
such as PIR and microwave. Requiring appropriate responses from both
technologies can help reduce false alarms caused by environmental
conditions.
7. Which device allows an authorized person to enter a controlled
area using a coded credential?
A. Access-control reader
B. Siren
