The Camden Door Controls CM-221M/46N is a Valuewave NG series exit device with override, designed for access-controlled door applications in commercial and institutional buildings. This unit serves as a push-to-exit or request-to-exit component, allowing free egress while integrating with electronic access control systems. The override function gives facility managers or security personnel the ability to bypass normal exit logic when conditions require it. Licensed electricians and low-voltage access control technicians are the primary trades responsible for installation and commissioning of this device.
The CM-221M/46N is suited for commercial entry and exit points where controlled egress is required, such as office buildings, schools, healthcare facilities, and secured corridors. It fits into access control systems where a push-button exit trigger or request-to-exit signal must be generated at the door. The override capability supports scenarios where standard exit logic must be temporarily suspended, making it practical for security desk integration or emergency egress management workflows.
Designed as an OEM-style exit device for commercial access control systems requiring a request-to-exit or push-to-exit input with override capability.
Installation should be performed by a licensed electrician or certified low-voltage access control technician familiar with applicable codes, including NEC guidelines for low-voltage control wiring. Disconnect all power to the access control panel and associated door hardware before beginning installation. Verify door frame preparation and wiring rough-in are complete prior to mounting the device. Consult the manufacturer datasheet for wiring diagram and mounting orientation details specific to the CM-221 series.
