EliteCEU Alarm Level 1: Fresh Exam Prep (1-250)
1. In a "Normally Open" (NO) circuit, an alarm is triggered when the circuit is:
A) Broken
B) Completed (Closed)
C) Shorted to ground
D) Doubled in resistance
Rationale: NO circuits are commonly used for "Panic Buttons" or "Fire Pull Stations"; when the
button is pushed, the contact closes, allowing current to flow and notifying the panel.
2. What is "Ohm’s Law" formula to find Voltage (V)?
A) V = I x R (Current multiplied by Resistance)
B) V = I / R
C) V = R / I
D) V = I + R
Rationale: Voltage is the product of the flow (current) and the opposition (resistance).
3. Which NEC Article covers "General Wiring Methods" including how to secure cables?
A) Article 250
B) Article 300
C) Article 760
D) Article 800
Rationale: Article 300 provides the fundamental rules for all wiring, such as protection from
physical damage and hole-drilling requirements.
4. A "Photoelectric" smoke detector is most effective at detecting which type of fire?
A) Slow, smoldering fires (like a lit cigarette on a sofa)
B) Fast, flaming fires (like a grease fire)
C) Electrical fires only
D) Outdoor brush fires
Rationale: Photoelectric sensors use light scattering to detect the larger smoke particles
produced by smoldering fires.

5. What is the standard "Supervisory" resistor value for a 12V alarm zone?
A) 0 Ohms
B) 1k to 10k Ohms (varies by manufacturer, e.g., 2.2k or 5.6k)
C) 1,000,000 Ohms
D) 12 Volts
Rationale: End-of-Line (EOL) resistors provide a specific baseline resistance that allows the
panel to monitor the integrity of the wire.
6. When using a "Step-Down" transformer, if the input is 120VAC, what is a typical
output for an alarm panel?
A) 5VDC
B) 24VDC
C) 16.5VAC
D) 120VAC
Rationale: Most residential alarm transformers step down 120V house power to 16.5V or 24V
Alternating Current.
7. In a "Series" circuit, if one sensor is removed or the wire is cut, what happens to the
rest of the loop?
A) The entire loop opens and reports an alarm/trouble
B) Only that one sensor stops working
C) The panel catches fire
D) The resistance drops to zero
Rationale: Because there is only one path for current in a series circuit, any break stops the
flow for the entire loop.
8. What is "Ampacity"?
A) The maximum current a wire can carry safely without melting the insulation
B) The speed of the siren
C) The weight of the battery
D) The length of the wire run
Rationale: Ampacity is determined by the wire gauge (AWG) and the type of insulation used.
9. Which OSHA-approved tool is used to test if a circuit is "Live" without touching the
wire?
A) Wire Strippers
B) Non-Contact Voltage (NCV) Tester
C) Multimeter
D) Lineman's Pliers
Rationale: NCV testers detect the electromagnetic field around live AC wires, providing a safe
visual or audible warning.
10. What is "EMI" (Electromagnetic Interference)?
A) Electrical noise from high-voltage lines that can cause false alarms in low-voltage
, 2026 UPDATED QUESTIONS DOWNLOAD
sensors
B) A type of motion sensor
C) A brand of alarm panel
D) Emergency Maintenance Instructions
Rationale: EMI occurs when alarm wires are run too close to AC power lines, inducing "noise"
into the system.
11. A "PIR" sensor detects motion by monitoring changes in:
A) Sound waves
B) Radio frequencies
C) Infrared (heat) energy
D) Air pressure
Rationale: Passive Infrared sensors "see" the heat emitted by humans moving across their
field of view.
12. What is the purpose of a "REX" (Request-to-Exit) sensor in Access Control?
A) To automatically unlock a door when someone approaches from the inside
B) To lock the door harder
C) To take a photo of the user
D) To call the police
Rationale: REX sensors (often PIR or a button) ensure that users can exit a secured area
without needing a badge.
13. In "Video Surveillance," what does "Resolution" measure?
A) The weight of the camera
B) The clarity of the image (measured in pixels)
C) The speed of the hard drive
D) The length of the cable
Rationale: Higher resolution (1080p, 4K) provides more pixels, allowing for better identification
of faces or license plates.
14. What is a "Dry Contact" relay?
A) A switch that opens or closes but provides no electrical power of its own
B) A contact that isn't wet
C) A broken wire
D) A wireless sensor
Rationale: Dry contacts are "passive" switches used to trigger external devices like garage
door openers or lighting controllers.
15. Which notification device is required by the ADA (Americans with Disabilities Act)
for fire alarms?
A) A louder siren
B) A faster internet connection
C) Visual Strobes (with specific candela ratings)
, 2026 UPDATED QUESTIONS DOWNLOAD
D) A red keypad
Rationale: Strobes ensure that individuals with hearing impairments are alerted to an
emergency via light.
16. What is "Primary Power" for an alarm system?
A) The backup battery
B) The 120VAC house power via the transformer
C) The solar panel
D) The technician's battery pack
Rationale: Primary power is the main utility power that runs the system day-to-day.
17. What is "Secondary Power"?
A) The Standby Battery (Lead-Acid)
B) The neighbors' power
C) The secondary siren
D) The internet connection
Rationale: The battery acts as secondary power, keeping the system alive if the building loses
AC electricity.
18. What is a "Tamper Switch"?
A) A small switch that triggers an alarm if the panel box is opened by an intruder
B) A switch used to turn off the siren
C) A button for the technician to reset the system
D) A type of light switch
Rationale: Tamper switches protect the control equipment from being physically sabotaged.
19. Which wire gauge is thinner: 18 AWG or 22 AWG?
A) 18 AWG
B) 22 AWG
C) They are the same
D) Gauge doesn't matter for alarms
Rationale: In the American Wire Gauge system, the higher the number, the thinner the wire.
20. What is a "Duress Code"?
A) A special code that disarms the system but silently notifies the monitoring station of
a robbery
B) A code that is hard to remember
C) A code used for the front gate
D) A code that only works on weekends
Rationale: Duress codes are used when a victim is forced to disarm their system under threat.
21. What does "NFPA" stand for?
A) National Fire Prevention Agency
B) National Fire Protection Association
C) National Fire Prevention Academy
