Electric garage door operators are electrical devices that are used in opening doors to the garage either remotely or using various hard-wired controls. Security of your garage is very important and you should have a device that ensures it day and night. There are many benefits of using these electrical devices in your garage. They include convenience, safety and security. Currently, there are many brands of the operators in the market from different manufacturers. However, you can have the device custom-made for you.
Custom devices are made with consideration of the details of your existing application. They are made with adherence to your instructions to ensure easy installation and efficiency. When buying the device for your application, it is imperative that you invest in superior quality products. Current market has many cheap, noisy and non-compliant electric garage door operators. Such devices will not only give you a hard time trying to fit them in the door to your garage, but they are also dangerous and illegal.
Some devices are in the market because there were many door openers that operated in the similar radio frequency with them. These are the second stage development devices. Advanced and secure openers are now available in the market. They require a code of about 9 receiver dip switches that correspond to those of the transmitter.
The code system gives electric door openers 28 to 256 different codes. However, this system does not really cater for security exclusively. The idea behind their design was to avoid interference with the other door openers. Security seems to have been an afterthought of their designers.
In terms of the drive method, toothed nylon belt, cables and screw-drive operation, advances were made on the devices. However, these were just basics when compared to the latest electric garage door operators. By applying enough force on the door panel, you can force the door backward.
Latest devices use innovative technology. Their frequency spectrum ranges from 433 to 868 MHz with most of them relying on rolling or hopping code technology. Transmitter encoders and receiver decoders work on the basis of the rolling code which hinders recording and replaying of the codes by perpetrators who may want to access the garage. Since the signal is significantly different from that of other doors, nobody else apart from the garage owner can open the door. Through the encoder, a new code is generated when a code is sent by the transmitter.
On receiving a correct code, the receiver uses a similar encoder and an original seed in generating a new code. Look-a-head codes are generated by the receiver and transmitter in advance because someone might accidentally press the open button while out of range desynchronising the code. Remote controls of the roller shutter use this system as well as the sectional, over and up openers.
In addition, the latest devices are accompanied by tow and boom arm system that ensure that the door is firmly closed and locked properly. Security is the main feature of modern devices. This implies that, with the latest electric garage door operators you can rest assured of safety and security of your garage.
