Von Duprin launched the present motor driven Chexit device on 8/24/2015 and discontinued manufacturing the solenoid driven Chexit devices at that time..
The current Chexit Circuit Boards/Modules are not compatible with the older solenoid driven Chexit devices.
The most common, standard 15 Second Delay Module for the solenoid driven Chexits manufactured before 8/24/2015 was part 050228.
This old part may be available through a wholesaler such as SecLock (check with them for availability).
If a different Delay time is desired (between 0 and 60 seconds*) or any other special feature is required, a new motor driven Chexit device would be required (specify the desired delay time in the description of the device when ordering).
*Over 15 second delay requires a letter of approval from the authority having local jurisdiction over the premises prior to the installation of the device.
Allegion cannot grant such approval nor does it warrant local jurisdiction compliance.
