I want my fire door to hold open at 90° until someone pulls it, then the door closer kicks in and closes it as normal. What product will do this?

October 22, 2011 by  

Under Fire Regulations fire doors must not be held or propped open.  Without using an electromagnetic hold open door closer wired into the fire alarm, the only suggestion is to use a delayed action door closer, which can hold the door open for up to 90 seconds, then closing as normal.  I recommend the Geze TS4000S door closer.
