Door Holder W/Less Dorgard Smartsound Bk

Dorgard SmartSound is a wireless solution for legally holding open fire doors, automatically releasing them to close when a fire alarm sounds. SmartSound technology means the door units are not triggered by the noise of a vacuum cleaner. SmartSound listening technology means 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.
