What is a sensing edge system and where would you need or want to use a sensing edge system?

Well as we all know a few years back, any UL operator would need  one of two safety systems, either a line of sight hold-to-close manual button or it had to be equipped with a monitored reversing device when wired to auto-close, it could be applied in two different situation, the N.O. trigger relay to reopen or hold open a device when the edge is compressed and the N.C. supervised circuit which meant that any loss of continuity in the circuit would cause a closing door to reopen and an open door to remain that way… While the photo cell will work in most cases, the reversing edge system can easily and inexpensively add that second layer of protection and prevent a “crush” incident when the photo cell is not crossed or tripped as can very easily happen in applications with slide or swing gates where you cannot cover the moving span of the actual gate with the infrared of the photocell.

These safety edges come in a myriad of styles, with tracks or without tracks, hard wired and wireless, they even come ready to resist extreme temperatures like freezer doors and hangar doors.

So give us a call and let us set up the right edge for you, so that it adds safety and professionalism to every one of your installations.

I have a 2015 F350 King Ranch truck. How do I make the truck learn the Nice Era One 2 button remote code?

Question: Walter has a programming issue with his new truck: I have a 2015 F350 King Ranch truck. How do I make the truck learn the Nice Era One 2 button remote code?

Answer:  Good morning Walter, and may I begin by saying “Nice truck”!!! The Lear Car2U® Home Automation System integrated into your Ford King Ranch is a universal transmitter that includes two primary features – a garage door opener and a platform for remote activation of a gate. The system’s opener function replaces the common hand-held door opener with a three-button transmitter that is integrated into the interior of your 2015 Ford King Ranch, unfortunately the 433 MHz frequency that the Nice-Apollo transmitter uses cannot be programmed into the Car2U system. The good news is that Lear, the makers of Car2U will send you a receiver that integrates seamlessly into your gate operator and is easy to install and program. Their number is 866-572-2728 and their website is:

What is CE?

The CE mark, or formerly EC mark, is a mandatory conformity marking for certain products sold within the European Economic Area (EEA) since 1985.[1] The CE marking is also found on products sold outside the EEA that are manufactured in, or designed to be sold in, the EEA. This makes the CE marking recognizable worldwide even to people who are not familiar with the European Economic Area. It is in that sense similar to the FCC Declaration of Conformity used on certain electronic devices sold in the United States.

The CE marking is the manufacturer’s declaration that the product meets the requirements of the applicable EC directives

Countries requiring the CE marking:

CE marking is mandatory for certain product groups within the European Economic Area (EEA; the 28 member states of the EU plus EFTA countries Iceland, Norway and Liechtenstein) plus Switzerland and Turkey. The manufacturer of products made within the EEA and the importer of goods made in other countries must ensure that CE-marked goods conform to standards.

As of 2013 CE marking was not required by countries of the Central European Free Trade Agreement (CEFTA), but members Republic of Macedonia, Serbia, and Montenegro had applied for membership of the European Union, and were adopting many of its standards within their legislation (as did most Central European former member countries of CEFTA that joined the EU, before joining)

What is UL?

UL (Underwriters Laboratories) is a safety consulting and certification company headquartered in Northbrook, Illinois. It maintains offices in 46 countries. UL was established in 1894 and has participated in the safety analysis of many of the last century’s new technologies, most notably the public adoption of electricity and the drafting of safety standards for electrical devices and components.

UL provides safety-related certification, validation, testing, inspection, auditing, advising and training services to a wide range of clients, including manufacturers, retailers, policymakers, regulators, service companies, and consumers.

A good nine-word summary used by UL is, “A not-for-profit organization dedicated to public safety.”

UL sets standards for different product categories and tests products to make sure they meet the standards. In this way, UL is similar to the CE marking organization. UL may also certify the installation of products in the field.

Underwriters, by the way, are insurers. According to Encyclopedia Britannica, “The word underwriter is said to have derived from the practice of having each risk taker write his name under the total amount of risk that he was willing to accept at a specified premium.”
