LifeDoor – Local Firefighter’s Invention May Be A Lifesaver

October 1, 2017



Joel Sellinger is a local firefighter with a life-saving idea.

Joel Sellinger is a local firefighter who has come up with an invention that could save lives in the event of a fire. LifeDoor is a small device that you attach to a hinge pin on your bedroom door. In the event of a fire the device responds to your smoke detector and automatically closes the door, lights up and sounds an alarm.

“I’ve been a firefighter for five and a half years and have seen time and time again the difference between a closed door versus an open door in a fire,” Sellinger told “I began thinking with so much home automation there must be a way to close an open door in connection with a smoke alarm.”

Sellinger got together with a hometown friend and began working on ideas and prototypes and the two came up with LifeDoor.

According to Underwriters Laboratories Firefighter Safety Research Institute people once had an average of 17 minutes to escape a burning home after the activation of a smoke alarm. Today, that time has dropped to three minutes or less due to materials used in furnishings, homes incorporating more open layouts and lightweight construction materials, all contributing to fires spreading much quicker.


There’s a nationwide campaign to get you to close your door when you go to bed.

UL FSRI research reveals closed doors dramatically decrease heat and CO levels versus open doors, providing trapped occupants more time to react and escape if they can do so safely. UL has developed a public relations campaign to get people to shut their door when they go to bed. “Close before you Doze” is the campaign that features a website and related material to encourage people to close their doors when they go to bed.

“Open door versus closed door could mean life or death,” said Steve Kerber, UL Director of Firefighter Safety Research. “It’s important that when everyone goes to sleep at night that they sleep with their doors closed. Lives will be saved if more people hear the message to close your door.”

“When I’m away from home on shift my wife likes to sleep with the bedroom door open so she can hear our daughter come home,” said Sellinger.”People have pets that come and go, there are all kinds of reasons people leave their bedroom door open and LifeDoor is being developed with those people in mind.”

LifeDoor works on any door with a hinge pin.

Right now LifeDoor is still in development stage. Sellinger says they hope to bring it to market next year online and a retail. As with any startup, financing has been an issue and he may do a kickstarter campaign to raise funds.
