After the 1991 passage of the Americans with Disabilities Act, accommodating design became a prerequisite instead of an afterthought for businesses that serve the public. Even for private homes, ADA guidelines provide a good starting place in case your guests–or even you–face disabilities down the road. Keep reading to find out more about ADA regulations and how to make sure your venue can accommodate everyone who walks through your doors.

What the Americans with Disabilities Act covers

The future looks bright here at Mr. Electric®, and we hope the same for you! As you are mentally preparing for the New Year ahead, maybe you are planning your goals and resolutions for personal development and improvement. This video by our president, Joel Worthington, is sure to motivate you to achieve them. We also want to encourage you to consider your home’s development and improvement, too!

When you think about your home’s electrical system, what can be improved? What can be replaced and updated? We have put together five tips to help you get started on getting your home’s electrical system in tip-top shape for the New Year. 

Although they initially cost higher, LED Energy Star qualified bulbs end up paying for themselves in energy savings in about 10 years. They use 75 percent less energy than incandescent bulbs and last 35 to 50 times longer. Plus, they offer more peace of mind since they emit very little heat, decreasing the threat of an electrical fire, and are much more durable, so they won’t shatter all over the floor. They’re also guaranteed for three years minimum, which is above and beyond the industry standard, so you’ll save on maintenance costs as well as energy costs. Basically, there’s no excuse not to get them!

Did you know that you’re technically supposed to do this every month? Not many consumers actually do this, but a new year is a great time to put this to practice and schedule it along with your other monthly home maintenance routines. You’ll find these outlets in moisture-prone areas such as the kitchen and bathroom as the current National Electrical Code requires. Simply press the test/reset button and make sure the outlets trip and resent correctly. If they are malfunctioning, call your local Mr. Electric to have them replaced to reduce electrocution risk.

Replacing the batteries should be done at least once a year, and both of the detectors should be tested monthly to ensure proper functionality. And speaking of replacing, how old are your detectors? Remember that smoke detectors need to be replaced every 10 years. Depending upon the model, older model carbon monoxide detectors should be replaced every three years, and the newer ones, every 5-6 years. Make safety a priority for your home and get this done!

Power surges can enter your home unexpectedly during a stormy night, a random power company disruption or operation of a heavy-duty electrical appliance. They destroy electronic devices in their path and at times cause fires as well. It is unfortunate when your Mac or PC dies, but even more so when your photos, documents, music and other personal content are lost along with it as well. To reduce damage from power surges, have a whole house surge protector installed by your local Mr. Electric at the panel and additionally multi-outlet power strip surge protection for delicate circuitry, telephone and cable lines. This will ensure both main zone as well as secondary zone surge protection to absorb any excess power that seeps through the primary protection.

This can be done in a variety of ways: turning lights out after you leave a room, unplugging and turning off electrical devices when not in use and ensuring lighting and appliances are Energy Star qualified. Perhaps you can create a friendly family competition to see who can use the least amount of electricity, or even consider looking into installing a solar energy system for your home. Whatever you choose to do, remember that you can also call your local Mr. Electric to perform an energy audit for your home to ensure its electrical system is operating at maximum efficiency.

We hope you find these tips helpful to make your home’s electrical system the best and brightest it can be, and we wish you a Happy New Year from all of us at Mr. Electric!

A Programmable Logic Controller (PLC) receives information from one or more inputs. This semiconductor control device processes the information based on a software program. Finally, it sends an output control signal. The microprocessor based control system performs functions such as timing, logic, sequencing and others. The PLC follows instructions from an operator-defined program.

These intelligent systems provide reliable, high-speed monitoring and control of processes in automated applications. In addition, they are easy to program and configure.

Once the program updates the output, the CPU starts over and the cycle repeats again. The cycle depends on the number of inputs, outputs, and size of the program, while the action will depend on the inputs coming from a variety of sensors.

The input sensors include components such as switches, proximity sensors, photoelectric sensors, pressure switches, level switches, encoders and temperature sensors, while the output devices include actuators, relays, switches, and many more.

PLCs rely on software programs that help them in making the necessary decisions. The PLCs are programmed through a variety of tools, which may differ in ease of use, appearance, and complexity. The most commonly used PLC programming language is Ladder Logic, a graphical software that uses common electrical symbols. Other languages include Function Block Diagram (FBD), Sequential Function Chart (SFC) and Structured Text (ST).

The programming is done on the device such as a computer or handheld device after which it is transferred to the PLC memory using a communication interface.

Selecting a suitable PLC that will address your current and future needs can be a challenge, especially with the large number of different PLCs on the market today. The available PLCs have varying capabilities, physical sizes, complexity, cost, power requirements, scalability and other parameters. Therefore, it is necessary to determine the correct programmable logic controller for your specific application. Special systems can be designed for use in harsh environments.

The Programmable Logic Controller has revolutionized and simplified controls in automation and industrial applications. PLCs are easy to install, wire, program and modify to suit changing application requirements. These control systems are usually available in a wide range of sizes that ensure finding exactly what you need for any application.
