An electric opener does not directly open or shut the garage door. Instead, it relies on a set of counterbalance springs that are attached to the door to lift it. The tension from these springs lifts the door with the help of steel cables.

The cables are rolled up in a clockwise direction to open the door, and in a counterclockwise direction to bring it down. The door openers themself helps only to control how far the doors open and close, and to keep the door locked.

The Door openers’ power unit

Door openers have a power unit that houses the electric motor. This power unit is attached to a track that runs along the ceiling of the garage. A drive system (chain, belt or screw) extends from above the garage door and runs along the track to help raise or lower the door when the motor turns.

The door openers equipped with a quick release device too. It is incorporated in this system to switch to manual operations in case of power failures. Limit switches installed in the power unit controls how far the doors should open or close when it receives the signal from a push button or a remote control.

How does a remote controlled system function?

Just like any other remote control system, a garage door openers’ remote system too relies on low power radio frequency to function. It offers you the convenience of staying put and operating your garage doors from your car.

Few older versions of garage door openers were considered unsafe as one remote could potentially transmit to a neighbour’s receiver and open their doors. Their frequency had to be adjusted each time they opened a neighbour’s door.

However, modern remote operated systems have been designed with rolling security codes that are almost impossible to break. A new code is generated regularly to avoid the threat of stolen codes.

A series of switches are located within the remote and its’ receiver box for aligned operation.

Safety features in both door openers systems

The safety aspect of door openers as well as in Remote a Gate Automatic gate openers is given much importance as they are probably the largest automatic moving objects in homes. The risks of employing a system that is not equipped with the basic security features are many.

Key features include a manual operation option and a safety reversal system.

In the event of a power or mechanical failure, a manual operation system can keep you from getting stranded inside or out. Similarly, sensors that stop doors from opening or closing when there is an obstruction in its path are a must.

A few other factors too contribute towards the safety of door openers such as the speed at which the doors open or close, the height at which switches or manual operation ropes are fixed, security lights that power on when you drive into the garage, and lockout features where you can turn off your system when you are on vacation.
