Dorgard is a simple, cost-effective way of holding fire doors open in busy environments. It is screwed to the fire door and can hold the door open in any position. Its inbuilt microphone reacts to the sound of the fire alarm by releasing its grip on the floor - thereby allowing the door to close. It is not wired-in or connected to the fire alarm system in any way.
