The standard Von Duprin Chexit device and DE5300 Delayed Egress System does not have an automatic reset option because most of the codes that apply to a Chexit device do not allow that feature..
The Chexit device or DE5300 can be reset locally using a key or remotely using an access control system depending on local code requirements.
For example, California requires that the key switch built into the device be used to reset an alarmed Chexit device or DE5300.
There is an uncommon BOCA building code that required a slightly different operation.
