Questions and Answers

1.

Resistors that are connected end-to-end are considered to be wired ______.
- A.
  
  Incorrectly
- B.
  
  In series
- C.
  
  In parallel
- D.
  
  In perpetuity
Correct Answer
B. In series

Explanation
When resistors are connected end-to-end, they are considered to be wired in series. In a series circuit, the current flows through each resistor sequentially, meaning that the same current passes through each resistor. This arrangement increases the total resistance in the circuit, as the resistors add up.

- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
F – EOLs (end-of-line resistors) are included to supervise the wiring and are required by both the manufacturer’s installation instructions and other requirements.

3.

There are no longer any conditions in which the use of an RJ31x jack is useful.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is false because there are still conditions in which the use of an RJ31x jack is useful. An RJ31x jack is commonly used in alarm systems to provide a dedicated line for the alarm to communicate with the monitoring center. It allows the alarm system to seize the phone line and dial out even if a phone is in use on another extension. Therefore, the use of an RJ31x jack is still relevant and necessary in certain situations.

Batteries installed on a burglar alarm system are required by code to be changed ______.
- A.
  
  Every year
- B.
  
  Every four years
- C.
  
  When service is performed
- D.
  
  No such requirement exists
Correct Answer
D. No such requirement exists

Explanation
The question is asking about the requirement for changing batteries on a burglar alarm system. The correct answer is "No such requirement exists," indicating that there is no specific code or regulation mandating the regular replacement of batteries for burglar alarm systems. This means that the batteries do not need to be changed on a specific schedule or when certain services are performed.

Burglar alarm panels today are manufactured to meet ______ standards.
- A.
  
  MD-01
- B.
  
  ECV
- C.
  
  NFPA 731
- D.
  
  CP-01
Correct Answer
D. CP-01

Explanation
Burglar alarm panels today are manufactured to meet CP-01 standards. CP-01 is a standard developed by the Security Industry Association (SIA) that aims to reduce false alarms and improve the effectiveness of alarm systems. It provides guidelines for features such as alarm duration, alarm verification, and communication methods. By complying with CP-01 standards, manufacturers ensure that their alarm panels are reliable and meet industry requirements.

The agency that is not a recognized NRTL for alarm system purposes is ______.
- A.
  
  ETL
- B.
  
  CFM
- C.
  
  UL
- D.
  
  FM
Correct Answer
B. CFM

Explanation
CFM is not a recognized NRTL (Nationally Recognized Testing Laboratory) for alarm system purposes. NRTLs are independent organizations that have been recognized by the Occupational Safety and Health Administration (OSHA) to test and certify products for safety and compliance with relevant standards. ETL, UL, and FM are all recognized NRTLs, but CFM is not. Therefore, CFM cannot provide the necessary certification for alarm systems.

7.

To measure the resistance of an alarm circuit the technician would need ______.
- A.
  
  To place the meter leads across the live terminals
- B.
  
  A fully charged battery
- C.
  
  To open the circuit to avoid burning out the meter
- D.
  
  To disconnect the wires from the control panel
Correct Answer
D. To disconnect the wires from the control panel

Explanation
To measure the resistance of an alarm circuit, the technician would need to disconnect the wires from the control panel. This is necessary because measuring resistance requires isolating the component or circuit being tested from the rest of the system. By disconnecting the wires from the control panel, the technician can accurately measure the resistance without interference from other components or circuits.

Residential 4 wire smoke detectors must be wired with ______.
- A.
  
  End-of-line resistors and a power supervision module
- B.
  
  24-gauge wire
- C.
  
  An end-of-line resistor
- D.
  
  Only one device per zone
Correct Answer
A. End-of-line resistors and a power supervision module

Explanation
A – 4 wire detectors must have both an end-of-line resistor and a power supervision module to supervise the wiring and power to the device.

9.

What is the result of connecting batteries in series?
- A.
  
  It requires a larger transformer
- B.
  
  Backup standby time increases
- C.
  
  Resistance decreases
- D.
  
  Voltage increases
Correct Answer
D. Voltage increases

Explanation
Connecting batteries in series increases the voltage. When batteries are connected in series, their voltages add up. For example, if two 1.5V batteries are connected in series, the total voltage would be 3V. This is because the positive terminal of one battery is connected to the negative terminal of the next battery, creating a cumulative effect. Therefore, connecting batteries in series results in an increased voltage.

______ burglar alarm installations are regulated by ______.
- A.
  
  Combination fire and / NFPA 101
- B.
  
  Commercial / UL 681
- C.
  
  Residential / NFPA 731
- D.
  
  Listed / NFPA 70
Correct Answer
B. Commercial / UL 681

Explanation
Commercial burglar alarm installations are regulated by UL 681. UL 681 is a set of standards and guidelines specifically designed for commercial burglar alarm systems. It ensures that these systems are installed and maintained in a safe and effective manner to provide maximum security for commercial properties. This regulation helps to ensure that commercial establishments are protected against burglaries and other security threats.

Panic buttons are usually wired as a/an ______ circuit, with ______ wiring.
- A.
  
  Closed / series
- B.
  
  Open / series
- C.
  
  Closed / parallel
- D.
  
  Open / parallel
Correct Answer
D. Open / parallel

Explanation
Panic buttons are usually wired as an open circuit, meaning that the circuit is incomplete until the button is pressed. This allows for a signal to be sent when the button is pressed, indicating an emergency. Additionally, the panic buttons are typically wired in parallel, meaning that they are connected to the same power source and can all trigger the alarm system simultaneously. This ensures that the alarm is activated no matter which panic button is pressed.

A Class B fire alarm circuit requires a resistor to be placed at the last device on the circuit.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
In a Class B fire alarm circuit, the circuit is divided into zones and each zone has multiple devices connected to it. In order to ensure that the circuit remains functional even if there is a break or fault in the wiring, a resistor is placed at the last device on the circuit. This resistor allows the circuit to continue functioning by providing a path for the current to flow even if there is a break in the wiring. Therefore, the statement that a resistor is required to be placed at the last device on the circuit in a Class B fire alarm circuit is true.
