Power and Electricity
$168.00
Course Length: 6 Hours
This is a six-hour course that will provide students an overview of power and electricity; from choosing a power supply, powering components for access control, intrusion, and video, as well as electricity components.
Learning Objectives
Power Supplies
- Using a manufacturer’s specification sheet, read and interpret the manufacturer’s specifications (voltage, permissible load, etc.).
- Using the NTS worksheet (found in the NTS Dictionary) and the manufacturer’s specifications, the student will be able to determine the minimum size power supply needed.
- Using an NTS worksheet and the manufacturer’s specifications, the student will be able to calculate the size battery needed for a system to operate for specified number of hours (4, 24, 60, 72) without primary power.
- Using the NTS worksheet and manufacturer’s specifications, the student will be able to calculate the size battery needed for a system to operate without primary power as required by NFPA and UL requirements.
- Select the proper transformer for power supply as well as install and wire the transformer.
- After determining the proper battery, list reasons for its failure for a given system.
Choosing a Power Supply
- Describe what features and environmental factors to consider when choosing a power supply for an alarm system.
- Explain the purpose of a transformer and the difference between a step-up transformer and a step-down transformer.
- Understand how to calculate the maximum normal load and alarm load for secondary power.
- Understand how to calculate the battery amp hours needed for different categories of alarm systems.
- Explain the two categories of power and what supplies the power.
- The two ways of connecting batteries to an alarm system and the characteristics of each.
System Power and Intrusion
- Determine the need for, and the proper methods for providing surge protection.
- Configure a switch and a contact.
- Address long wire runs (heavier wire vs. local power supplies)
Powering Components and Access
- Describe the primary power requirements for an Electronic Access Control (EAC) system
- Explain secondary power requirements for fail safe and non-fail-safe devices.
- Identify surge protection components that are commonly used in conjunction with an EAC system.
Power and Video
- Describe Ohm’s and Watt’s Laws as well as the relationship between Ohms, Amps, Volts, and Watts.
- List the kinds of components you will need to consider when determining the total load of a circuit.
- Elaborate on how to choose the appropriate size wire for a given distance.
- Identify the major types of power for cameras, i.e., AC, DC, and POE.
- Define Transformers and distributed power supplies and state their benefits.
Electricity
- Define current, voltage and resistance and the unit of measurement and symbol used for each.
- Explain the function of a resistor and how to identify resistor ratings.
- Explain the function of a conductor and describe the different conducting materials.
- Explain the function of an insulator and describe different insulating materials.
- Describe the theory of circuits, simple series, and parallel circuit.
- Describe how to find all the values of a circuit when provided with the necessary information.
- Describe the formula for finding power using Watt’s Law and Ohm’s Law.
What to expect in this course: The presentation includes text, audio, graphics, videos and activities to help you absorb the information presented. This course has a short quiz at the end, which you will be required to pass with a 80% or greater to complete the course.

If the student has completed less than ¼ of the course and a request is made to cancel, a refund is available less a 25% administrative fee. Students may choose to transfer their funds to another ESA/NTS provided course if less than ¼ the course has been completed. Transfers will not be issued until the class materials, including the course manual, is returned in like new condition to ESA/NTS. Fund transfers cannot be made to non-ESA/NTS courses due to the varied payment terms established by the Training Providers. Cancellation requests made beyond one-quarter through the course will not be refunded or transferred. Refunds should be expected within thirty days of receipt of returned materials.Live In-Person and Virtual Courses
Provider Cancellation Policy: Training Providers may cancel a class with at least 5 calendar days’ notice to pre-registered students. Classes may be cancelled without advance notice due to weather conditions or other unforeseeable emergencies. The Training Coordinator determines the conditions that constitute an emergency. All monies paid to the Training Provider for a class that is cancelled shall be fully refunded within 14 business days of the cancellation notice. Students may choose to have their monies credited towards another scheduled class. Students should contact the Training Provider for additional terms and conditions regarding their refund policy. Student Cancellation Policy: If a student cancels an ESA National Training School course more than seven days prior to the class, a refund, less a 25% administrative fee, will be issued. In lieu of canceling, a student can opt to transfer their funds to a future course. There are no refunds or transfers permitted within seven days before the class.Returns should be sent to: Attn: PO Box 610605 Dallas, TX 75261
Returned items should include a letter regarding the nature of the return, include the student’s name, telephone number and email address.
