Abstract
The present disclosure relates to touchless, pushbutton exit devices, systems and methods thereof. A touchless, pushbutton exit device of the present disclosure is a touchless door-control device designed to provide both contactless, fail-safe, egress/exit control as well as push-button egress/exit control. The touchless, pushbutton exit device can be used in conjunction with a host of existing security devices (e.g., Fire, Alarm Panel, and Access Control), or as a stand-alone solution. The present disclosure provides for at least three types of exit devices, i.e., an Infrared (IR) version, a Doppler (radar) version and a low-power radar-based version. When motion is detected within a predetermined distance (e.g., about 5.5 inches for the Infrared version or about 24 inches for the Doppler version) of a faceplate of the exit device, an onboard relay is activated, providing control for intermittent as well as continuous duty locking devices.
