Door Closers Access Control Tutorial

Published Sep 10, 2021 12:54 PM

Door closers have an essential access control function: To automatically shut doors, because open doors do not control access.

In this tutorial, we review door closers, examine how they are selected, and show how to avoid misusing them:

  • Why closers are important for access control
  • Why using closers as barricade locks is often illegal
  • Applications other than security where closers help
  • What normal closer operation should look like
  • The 3 standard movement phases and configuring locks for them
  • How to properly size closers
  • Typical closer pricing
