A change made to the installation wrapper that gives user permission to modify files in the cone, data and dbases folder in the userdocs area
BRANZFIRE ver 2010.4
The smoke detector response time algorithm is modified to remove any dependence on the depth of the smoke layer in room of fire origin. Previously it was necessary for the layer depth to be not less than 100 mm as one of the requirements before a detector could operate. In some cases this change will shorten the predicted smoke detector response time.
