Rationales | 2025/2026 | Latest Update | Instant Download !!
1.
Under Texas Occupations Code, an Alarm Level II Technician may perform which of the following without
direct supervision?
A. Fire alarm system programming
B. Installation of basic alarm detection devices (correct answer)
C. Armed security patrol duties
D. Locksmithing services
Rationale:
Level II technicians are authorized to install and service standard intrusion detection devices. They may
NOT program fire systems, perform armed duties, or conduct locksmithing.
2.
Which NFPA standard is most relevant for intrusion detection system wiring installation practices?
A. NFPA 72
B. NFPA 70 (correct answer)
C. NFPA 101
D. NFPA 730
Rationale:
NFPA 70 (National Electrical Code) governs proper wiring methods and safety practices for low-voltage
systems, including alarm circuits.
3.
A Level II technician must carry which license while performing regulated services?
A. Their employer’s agency license
B. Their pocket card issued by DPS (correct answer)
C. A temporary work permit
D. A notarized authorization letter
Rationale:
DPS regulations require alarm technicians to carry their Level I or II pocket card at all times when
performing work.
4.
When installing magnetic contacts on metal doors, the installer must ensure:
A. The magnet faces the hinge
B. The gap distance does not exceed manufacturer specs (correct answer)
C. The magnet is installed upside down
D. The control panel is installed first
,Rationale:
Proper alignment prevents false alarms caused by door movement or vibration.
5.
A supervised zone is one that:
A. Includes two sensors on one loop
B. Can detect open, short, or ground faults (correct answer)
C. Is monitored by local law enforcement
D. Requires Level III certification
Rationale:
Supervision ensures the control panel detects tampering, shorts, or wiring breaks.
6.
The power supply for alarm control equipment must be sized to provide:
A. 4 hours standby and 5 minutes alarm
B. 24 hours standby and 4 minutes alarm (correct answer)
C. 12 hours standby only
D. Unlimited standby time
Rationale:
UL and industry standards require 24-hour standby plus alarm duration to ensure reliability during power
loss.
7.
A PIR sensor detects motion based on:
A. Sound waves
B. Pressure changes
C. Infrared energy variation (correct answer)
D. Electrical field fluctuation
Rationale:
PIR (Passive Infrared) sensors detect motion via heat changes emitted by objects in their field.
8.
Which of the following would most likely cause false alarms in a microwave motion detector?
A. Temperature changes
B. Large metal objects moving (correct answer)
C. Dust in the lens
D. Low battery voltage
Rationale:
Microwave sensors are sensitive to moving metal objects that can reflect and distort the detection signal.
, 9.
A customer reports that their magnetic contact alarm triggers every time the door is slammed. The MOST
likely cause is:
A. Low control panel voltage
B. Incorrect magnet alignment (correct answer)
C. Loose transformer screw
D. Faulty keypad
Rationale:
Misalignment or improper mounting allows the contact to open momentarily with door movement,
triggering false alarms.
10.
Texas DPS requires alarm companies to keep service records for:
A. 1 year
B. 2 years
C. 4 years (correct answer)
D. 7 years
Rationale:
Administrative Code mandates retention of service and installation records for four years for accountability
and inspection purposes.
11.
When calculating voltage drop on a 12V alarm circuit drawing 600mA over 120 feet of 22-gauge wire, a
technician should:
A. Ignore drop unless circuit exceeds 300 feet
B. Increase wire gauge to reduce resistance (correct answer)
C. Double the voltage output
D. Install a second transformer
Rationale:
22-gauge wire has high resistance; increasing the wire size reduces voltage drop and ensures devices operate
correctly.
12.
Which communication method is LEAST affected by power outages?
A. POTS landline
B. VoIP
C. Cellular LTE module (correct answer)
D. Wi-Fi
Rationale:
Cellular modules run on panel backup batteries and do not rely on power or internet, unlike POTS or VoIP.
