Dorgard SmartSound is a wireless solution for legally holding open fire doors, automatically releasing them to close when a fire alarm sounds. SmartSound listening technology means Dorgard SmartSound can distinguish between your fire alarm and common background noises, such as vacuum cleaners. Dorgard SmartSound knows the sound of your alarm straight out of the box. As soon as alarm is activated, the plunger is released and the door will close.
