Does the Dorgard only listen to sounds at 65db (Decibels)?
The Dorgard listen for a constant sound above or at 65db. The Dorgard can be setup so that it is more or less sensitive and this can be done by adjusting the sensitivity in the adjustment hole in the front. Although we do recommend that it be kept at 65db or higher it can be adjusted lower if the sounder is a bit further away however the door may close more often if the background noise creeps up. The higher sensitivity should only be used in nosy environments where a 65db constant sound level is exceeded i.e. a place that plays loud music. The maximum is 80db but should your premises have a background noise of this or higher it is unlikely that you will hear a 65db fire alarm sounder.
