1. What is the primary purpose of an alarm system control panel?
A. To provide electrical grounding for the building
B. To amplify sound from the alarm siren
C. To receive, process, and respond to signals from system devices
D. To replace all circuit breakers in the building
Rationale: The control panel is the central processing component of an
alarm system. It receives signals from initiating devices such as door
contacts, motion detectors, smoke detectors, and other sensors, then
determines what action should occur, such as sounding an alarm,
transmitting a signal, or activating programmed outputs.
,2. Which device is commonly used to detect the opening of a
protected door or window?
A. PIR detector
B. Glass-break detector
C. Magnetic contact
D. Heat detector
Rationale: A magnetic contact consists of a magnet and a switch. When
the protected door or window moves away from its frame, the magnetic
relationship changes and the switch changes state, allowing the control
panel to recognize the opening.
3. What does PIR stand for in alarm-system terminology?
A. Primary Input Relay
B. Power Isolation Resistor
C. Passive Infrared
D. Programmable Interface Receiver
Rationale: PIR stands for Passive Infrared. A PIR motion detector senses
changes in infrared energy, typically caused by a person moving
through its detection pattern.
,4. What is the principal function of an alarm system end-of-line
resistor?
A. Increase battery capacity
B. Increase the voltage supplied to detectors
C. Allow the control panel to supervise the integrity of a circuit
D. Eliminate the need for circuit wiring
Rationale: An end-of-line resistor, when required by the system design,
allows the control panel to distinguish among normal, alarm, and
trouble conditions. Its location and resistance value must correspond to
the manufacturer's installation requirements.
5. Which condition generally indicates that an alarm circuit has been
intentionally opened because of an alarm device activation?
A. Normal condition
B. Alarm condition
C. Grounded-neutral condition
D. Battery charging condition
Rationale: An alarm condition occurs when an initiating device changes
state in response to the condition it is designed to detect. The control
, panel interprets that change and initiates the programmed alarm
response.
6. What is the primary purpose of a backup battery in an alarm
control panel?
A. To increase the output of the siren
B. To replace the main power supply permanently
C. To maintain system operation when normal AC power is
unavailable
D. To prevent all false alarms
Rationale: Alarm systems commonly use standby batteries so that
essential system functions can continue during an AC power failure.
Battery capacity must be appropriate for the system's required standby
and alarm loads.
7. Which component converts incoming AC power into the DC voltage
required by many alarm system components?
A. Relay
B. Transformer only
