My recent posts about delayed egress locks have raised a question from a reader about the Remote Chexit Module (RCM).  What is this component used for and when should it be specified?  That’s a perfect question for a “What’s that?” post!

Most of you already know that the Von Duprin Chexit was designed as a delayed egress lock that can delay egress for 15 seconds, or 30 seconds when approved by the authority having jurisdiction (AHJ).  You may also know that this product can be used as a controlled egress lock in health care units where patients require containment for their safety or security.  In approved locations, controlled egress locks deter egress indefinitely, until evacuation is needed.  (The linked articles have more information about these applications.)

One thing to consider when specifying or supplying the Von Duprin Chexit is that it requires a certain minimum door width depending on which device configuration is used.  For example, on a CX98 series rim device, the minimum door width is 2′-10 3/4″.  What happens if you have an unequal width pair with a 3′-0″ leaf and a 2′-6″ leaf?  You can use the Remote Chexit Module (RCM) to achieve the same delayed egress functionality on the narrower door, by wall-mounting the electronic module and key switch.

If you have a suggestion for a post explaining the purpose of a component, feature, or option, leave a comment!
