Is Your Automatic Door Not Latching Properly?


There are multiple variables that can prevent your automatic doors from latching properly. Why is my door not closing fully? Why is the door bouncing out of its strike? These are the questions you may ask your service technician when dealing with stack pressure issues.

What is stack pressure?

Stack pressure is the movement of air in and out of your building. In the cities we serve here in Ontario, climates change constantly. With different pressure being seen in the summer and winter, there is a need for equalization from your HVAC system.

For example, in apartment buildings, our technicians have seen high winds from the exterior impact the operation of automatic door operators. In other words, apartment units, elevators, and HVAC systems can all work against the air infiltration from outside. If not properly pressurized, facility managers may have challenges keeping doors closed and secured.

Ironstone features the Dormakaba ED100 and 250 lines of door operators that have the ability to recognize this issue. The operator can adjust its closing force to make sure the door closes and latches properly.
