C.G. Johnson of Hartford City, Indiana is the man recognized as the inventor of the electric overhead garage door opener. It was first introduced in 1926. There is a common misconception among people that electric garage openers generate the power necessary to lift heavy garage doors. In reality, it is the counterbalance springs that are under tension that lifts garage doors through steel counterbalance cables.

The electric overhead opener dictates as to how far the door extends up or down and the force needed to enable movement in either direction. It also serves as a lock. Inside a typical electric garage door opener is a power unit — which is attached to a track — that houses the electric motor. A trolley linked to an arm that is attached to the top of the garage provides the back and forth action of the track, thus allowing the garage door to move up or down.

There is a chain, belt and screw mechanism that guides the trolley when the motor is turned on. You can also disconnect the garage door from the opener using a quick release mechanism in cases of machine failure or emergencies so that the door can be operated manually.
You can control the range of distance of the door during opening or closing via limit switches on the power control unit.

The whole assembly is attached above the garage door while the power unit is placed at the ceiling towards the back of the garage.

Remote Control
The first automatic garage door opener remote controls were simple in design using only a transmitter (remote) and receiver which is responsible for the opener mechanism. The transmitter used a unique frequency and the receiver upon recognizing the signal would either open or close the garage door depending on how the door is positioned.

This system was actually an application of a World War 2 technology for detonating bombs.
In its prime, it was considered cutting edge. However, it did not come without its downsides. Even if the remote emitted low frequency signals it was powerful enough to interfere with the operation of other similar mechanisms. It is possible to open or close an automatic garage door located next door using one remote.
Manufacturers were faced with this technical flaw and they soon developed mechanisms that would improve the remote’s technical design.

They discovered that the problem was rooted on shared frequency. To resolve this, they equipped remote controls with a range of frequencies from which owners can designate a frequency unique to their garage doors.

The third generation remote has features that would prevent individuals from duplicating or copying the frequency code of a particular remote and reprogramming it to a different remote to gain access to one’s garage doors. It uses hopping or rolling code technology in the remote’s mechanism. With this technology, a receiver is able to generate a different code every time it receives a signal from the transmitter. The new code that would be created will be unique to the garage door and will only respond when the correct transmitter is used.

Garage door openers are devices that one uses to open or close garage doors either from a remote or fixed location. Fixed garage door openers can be installed externally or internally while remote openers are handheld devices similar to TV remote controls with buttons for closing and opening doors.
Not to be confused with the counterbalance spring, garage door openers do not provide the power necessary to lift the heavy metal doors. Its purpose is to control the extent to which a door opens or closes.

The electric garage door opener was invented in 1926 by an American by the name of C.G. Johnson — a Hartford City, Indiana native.
The mechanism of the first remote control garage door openers were patterned after a World War II technology for detonating bombs. It is operated using a simple system of transmitters and receivers. Transmitters would send signals that receivers would pick up and depending on the position of the door, would either move it upwards or downwards.

Over the years, technology has enabled vast improvements on the remote control’s design and capabilities. Additional features that are standard in remote controls now are, 1) Automatic courtesy lights that would go off each time the door opens and turn off automatically after the expiration of a preset time delay 2) remote lockout feature which is activated when one is away for a vacation or away for extended periods of time 3) key chain remote 4)wireless keypads.
One pacesetter in the garage door opener industry is the Hormann Promatic Garage Door Opener. It is one of the quietest, fastest, and dependable garage door openers around.

It is equipped with 24V DC motors that ensure fast but quiet operation each and every time. It also uses a unique composite of nylon/Kevlar drive belt that is both durable and dependable. The material offers strength that is lightweight and is built for the long haul.
It also comes with hundreds of built in additional features that further empower owners and enhance user experience.

The Hormann ProMatic is Hormann’s starter opener model packed with features but sells at an attractive price. Security was top of mind when Hormann developed the Hormann Promatic.
Once it closes that, its motor and drive unit work in tandem to hold the door firmly closed. One added feature is a patented steel hook device that locks the towing arm and holds it in place to strengthen the structure and to prevent forced entry from taking place. This device can run even during power failure as it operates mechanically.

The double security lock feature of the motor and steel hook makes the Hormann ProMatic Opener one of the most secure operators in the market.
One can diversify the existing standard features by adding more capabilities and accessories to the device. One of these features is the highly advanced feature electronic finger reader that would enable your device to recognize up to 100 fingerprints available for an unbelievably low price.

Due to the sophistications and technology, electronic locks are obviously more expensive than manual key locks. The difference is that electronic systems have an outlet to public assistance like the local police and fire departments. This makes issues very convenient in the unfortunate event of an emergency. The downside is when malfunctions happen public assistance is notified for no reason. This process can be very aggravating to the customer and the emergency contacts.
