Overview

Dorgard SmartSound is a wireless solution for legally holding open fire doors and automatically releasing them to close when a fire alarm sounds. It combines the proven benefits of the well-known Dorgard platform with advanced SmartSound listening technology designed to filter out common background noise and improve alarm recognition performance in busy environments.

By allowing fire doors to remain open in day-to-day use, Dorgard SmartSound helps improve accessibility, convenience, ventilation and movement throughout a building. When the fire alarm is activated, the plunger is released so the door can close, helping to restrict the spread of fire and smoke.

Battery-powered operation, anti-drag performance, simple LED status indication and compatibility with heavy fire doors make Dorgard SmartSound a practical and professional solution for schools, hospitals, care homes, offices and many other commercial or public buildings.
