Wedging open fire doors is dangerous. Dorgard is a wireless solution that legally holds open fire doors and enables them to close when the fire alarm sounds.
This acoustically activated fire door retainer keeps a fire door open legally and closes the door in the event of an alarm.
Activated after hearing a general noise or continuous sound exceeding 65 decibels.
The door releases 14 seconds after sound activation.
