Dorgards are a Complete Wirelss Solution as it is a Battery Operated Self Contained device. The Dorgard constantly listens for a Sound above 65 db. Once the Fire Alarm sounds the Dorgard will pick up the noise and Appoximately after 14 seconds it will release and allow the Fire Door to close. The Dorgard is also capable of Automatically Releasing Doors at night for Maximum Protection.
How does the Dorgard Automatically Release the Doors?
Although the Dorgard can be used to hold open a Fire Door 24 hours a day, It is not ideal at night. The Dorgard has an Automatic Night Time Release Feature. Dorgards have an internal clock inside them, which allows the user to set a time for the Dorgard to Automatically Release a Fire Door. The Dorgard then will not operate as a Hold Open Device until the next morning at a time set by the user. This reduces the risk of Fire Spreading at night and Provides Maximum Protection 24 hours a day.
