A garage door opener, also known as garage opener, is an electronic device that manually opens and closes garage door, usually controlled by electronic switches installed on the garage wall. It is operated by a switch on the garage wall by means of an electric or mechanical drive mechanism. Garage Door Openers comes in various types and models based on their use and design. Some of them include automatic, manual, spring-loaded, wireless and automatic parallel/parallel garage door openers.
An automatic garage door opener motor consists of a heavy duty, permanent magnet DC motor with permanent magnet brush. The motor supplies the necessary force to lift and lower the trolley to the desired location. Many also come with a trolley carrying a handheld transmitter, which is used to operate and lift the trolley to the desired location.
Garage door openers are controlled through electric signals by a series of switches, usually mounted on the garage door opener motor itself. This makes it easy to adjust the setting without opening the actual device. Garage Door Openers generally has two major parts, namely: transmitter, and remotes. The transmitter is the part of the system that receives signals, and which transfers them to the remotes, which in turn act upon the signals. Some transmitters are dual mode, meaning they can be set for both automatic and manual operation.
There are a few types of garage door opener, namely: digital code remotes, or digitally controlled units; optical disc varieties; and key pads with touch-screens for numerical controls, or for programming codes into the system. Automatic Garage Door Openers uses either a manual or a digital code to program its settings. A digital code is decoded by the receiver of the signal and is used to control all functions of the unit. These can be programmed for remote controls, manual operation, or to limit the operation period of the unit.
Rolling Code Drive: Also known as a Coding Technique, these are also known as True Permanent Patterns, or TPC. In this method, a permanent pattern of numbers (code) is used to programmable resistive or electromagnetic gates or sensors, using a logic level. The remote control can sense the starting sequence number and then follows the code to determine whether to activate the motor. This is one type of garage door opener, which requires a power source. It is susceptible to power fluctuations and is therefore susceptible to failures.
Regular Maintenance: All garage door openers require some level of maintenance and lubrication. The lubricant, in this case, should be a low-water, long-lasting kind. Also, the timing belt should be inspected for signs of damage and then replaced if necessary. Exhaust systems must be inspected for leaks and then either repaired or replaced if necessary.
