Modern garage doors offer security, convenience, and power. In today’s tech-heavy world, these devices are also able to be used via smartphones, which gives them the ability to be integrated with smart-home systems and allows them to be used remotely. While these are great conveniences and can improve both security and convenience, there are a number of safety concerns that come into play as a result of these new capabilities. 

The UL Committee is a leading manufacturing safety and optimization organization that took up the challenge of making a new standard in modern garage door safety a reality. Mars International LTD is a prominent member of this committee. As a member of the UL committee, Mars’ mission, working for a safer world, was the guiding principle in our work on this project. One of the major points of concern on this topic was what is called “unattended operation.” Unattended operation is when the owner of an automated garage door operates the door when they are not in the immediate vicinity of the door. 

The safety hazards of unattended operation are obvious. Any person who is near the door when it opens or closes unexpectedly could potentially be injured.

The UL Committee set down a series of standards and garage door security ideas to which garage door remote operation systems should adhere. They are: 

  • A 5-second delay before actual closure can begin: This allows any person in the vicinity of a door that is being remotely operated to move to a safe distance and to remove obstructions that may interfere with the door or cause damage. During this period, the garage door operator must have an audible alarm and blinking light to warn anyone in the vicinity that the door is coming down. In addition, individuals can press any control (like a wall station) to cancel the remote operation. 
  • A two-attempt, obstruction reaction system: Should a remotely operated door encounter an obstruction, the device should sense the obstruction once encountered. It should have sufficient sensitivity to avoid damaging the obstructing object, and it should cease to attempt closure after two or fewer failed closures. 
  • Remote use should be limited to vertically and horizontally moving doors: Door types that are considered to be too difficult for mechanical systems to control safely should not be fitted with remote closure systems. 
  • One-piece, overhead, and swinging doors should not be capable of remote operation: Types of doors that require potentially dangerous levels of mechanical force to close should not be fitted with remote closure systems. 
  • Accessories sold as add-ons to existing garage doors should come with instructions explaining compatibility and adherence to safety codes: Any add-ons should comply with features that enable the safety features described in the guidelines. Add-ons and accessories should also come with documentation that helps users ensure these safety features are not limited or counteracted by add-ons. 
  • Accessories should deliver audio and visual alerts: add-ons should come with the ability to deliver an audible or visual alert system. This would indicate to any person near the automated door that closure (or other operation that can potentially cause injury) will commence within a five-second period. 

Ensuring that garage doors adhere to these guidelines will create a reasonable standard of safety, making recent mobile tech-related advancements safer for users. What’s more, these systems can be paired with or enhance any garage door security system by delivering audible and visual alarm systems that can deter criminal behavior. This enhances both the safety and the security profile for homeowners and business owners who are likely to deploy these devices on their property. 


  • Modern garage door safety has increasingly become a concern in our technologically-based world. 
  • Remote Garage door systems are being raised to a higher standard of utility, safety, and security to ensure users are protected. 
  • Mars International is proud to have been a part of the team that spearheaded these guidelines and to have had the opportunity to raise the level of safety and security users should expect.
