1. What is the primary purpose of an alarm control panel?
A. Detect motion
B. Supply power to sensors
C. Transmit video signals
D. Process inputs and control system responses
Rationale: The control panel is the “brain” that receives signals from
devices and activates alarms or notifications.
2. Which power source is required as a backup for most alarm systems?
A. Solar panel
B. Generator
C. Rechargeable battery
D. Wind turbine
Rationale: Backup batteries keep the system operational during power
outages.
3. What type of sensor detects changes in infrared energy?
A. Glass break sensor
B. Magnetic contact
C. Passive infrared (PIR) sensor
D. Smoke detector
Rationale: PIR sensors respond to heat changes caused by moving objects.
4. Magnetic contacts are commonly installed on:
A. Ceilings
, B. Windows and doors
C. Floors
D. Walls only
Answer: B. Windows and doors
Rationale: Magnetic contacts monitor the opening and closing of entry
points.
5. What does EOL stand for in alarm wiring?
A. End of line
B. Energy output level
C. Electrical overload
D. Emergency operating logic
Answer: A. End of line
Rationale: EOL resistors supervise wiring integrity.
6. Which wiring configuration provides the highest supervision level?
A. Normally open
B. Normally closed
C. End-of-line supervised circuit
D. Parallel circuit
Rationale: Supervised circuits detect opens and shorts.
7. What device detects the sound frequency of breaking glass?
A. Motion detector
B. Heat detector
C. Glass break detector
D. Door contact
Rationale: Glass break detectors analyze sound patterns.
8. Which communication method uses phone lines?
A. GSM
B. IP
C. Radio
D. POTS
Rationale: POTS refers to traditional landline communication.
9. What is the function of a siren?
A. Detect intrusion
, B. Notify monitoring station
C. Provide audible alert
D. Record events
Rationale: Sirens alert occupants and deter intruders.
10.Which code regulates fire alarm installations?
A. NEC
B. OSHA
C. NFPA 72
D. ANSI
Rationale: NFPA 72 is the National Fire Alarm and Signaling Code.
11.What voltage is commonly used in residential alarm systems?
A. 120 VAC
B. 240 VAC
C. 12 VDC
D. 48 VDC
Rationale: Most low-voltage alarm systems operate on 12 VDC.
12.What does a tamper switch detect?
A. Motion
B. Heat
C. Unauthorized opening of a device
D. Sound
Rationale: Tamper switches trigger alarms if devices are opened.
13.Which detector is best for detecting smoldering fires?
A. Heat detector
B. Photoelectric smoke detector
C. Ionization smoke detector
D. CO detector
Rationale: Photoelectric detectors are sensitive to smoldering smoke.
14.CO detectors detect which gas?
A. Oxygen
B. Nitrogen
C. Carbon monoxide
