1. Safety reversal: All the garage door opener equipped with safety reversal feature. The door has two sensors situated six inches above the floor level, both sides of the door. When any object like pet, child or anything else, get in touch with light beam created by sensor while the door is closing, the door stops and reverses. If your opener have not this safety reversal feature, change it as soon as possible.
One of the most important parts of the planning is the choice of either installing it yourself or seeking help from professional. If you do not have enough knowledge about the process of installation and you are not equipped with appropriate tools, then you must never attempt to install it yourself.
Some garage door openers already come with a fingerprint-based wireless keypad. This unit attaches to the outside of the garage door on the jamb and allows users to open and close their doors with the press of a finger, rather than creating a personal identification number (PIN). This is especially helpful for families and individuals who have a hard time remembering so many passwords or codes. More sophisticated garage door openers come with integrated carbon monoxide sensor to open the door in case of the garage being flooded with exhaust fumes. Other systems allow door activation over the Internet to allow home owners to open their garage door from their office for deliveries. The door must be in the line-of-sight of the person operating the door for safety reasons, and this feature violates Underwriters Laboratories (or UL) safety codes.
