Camden CX-33 Door Controller with Lockdown Switch

The CX-33 Door Controller is designed for universal operation in virtually any automatic door application.

Camden Door Controls announces its CX-33 advanced logic door controller with the addition of a built-in “lockdown” operating mode. The new feature will enable a designated (N/O) momentary emergency lockdown switch, or switches, to disable automatic door activation switches while also locking electric strikes or magnetic locks to prevent entry to a building, area or room under intruder conditions.

Lockdown mode is reset with a separate (N/C) momentary push button or key switch. The CX-33 is also equipped with an additional output that can be used to energize a lockdown status LED indicator.

The CX-33 is designed for universal operation in virtually any automatic door application, according to the company. It provides a large three segment LED and simple push buttons for the easiest programming, and supports illuminated signage in restroom applications.

Programmable modes include up to 3 door sequencing, airlocks, lock-out-relay, fire door in stairwells, and for control of automatic operators in restroom applications, with support of illuminated indicator of occupancy status.
