Von Duprin Chexit door label from Chexit installation instructions.
Last year Von Duprin began shipping Chexit self-contained delayed egress exit devices that are motorized instead of solenoid driven. Since they are motorized, the new Chexits draw less current and will probably be more reliable than the previous solenoid-driven version. This means a less serious, less expensive power supply, less need for high capacity, high gauge, high cost wire and greatly increased workable wire run distances – all good things.
The new Chexit will do everything the old Chexit did, including release of the outside lever trim when the external inhibit function is activated by access control or another external switch. That remains a way to get access control out of a Chexit by simply adding a blank escutcheon or other unlocked outside trim to the Chexit exit device.
As of this writing Exit-only function Chexit devices were being shipped less the part number 040193-00 cable used to connect the E996L to the Chexit PC board. The cables are only provided if you order the Chexit from the factory with trim, but that is okay as long as you want to use no trim or non-electric trim. Electrified trim is a means to provide fail secure access control from the trim side, so if the fire alarm goes off and powers down the Chexit, the fail secure electrified trim will stay locked. Entry can still be gained by key.
On another note, recently I was involved in an application where the installer was replacing a mortise exit device and wanted delayed egress from the push side and free ingress from the pull side. Luckily it was a mortise device, so all I had to do was provide a Chexit mortise exit device with blank escutcheon (passage function) trim because THE MORTISE LOCK ACTS INDEPENDENTLY FROM THE CHEXIT ON THE TRIM SIDE. Cool. 🙂
Bear in mind that the Chexit remains active while people are using the passage function trim to get in, so if they happen to depress the touch bar, say by bumping it up against the wall for two seconds, they may activate the Chexit alarm. Von Duprin Tech Support suggested a palm switch on the trim side to activate the inhibit circuit in the Chexit while a person enters from that side.
It was fun, easy, and I looked like a … Hardware Genius.
