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. ## Claims ### Claim 1 A device for controlling opening and closing of a barrier comprising: a face plate including a front surface and a rear surface, the face plate configured for mounting the device adjacent the barrier; a proximity detector disposed on the front surface of the face plate that detects an object within a predetermined distance of the proximity detector, an output of the proximity detector coupled to a controller and configured for providing an indication that an object was detected; a pushbutton disposed on the front surface of the face plate having an open state and a closed state, the button coupled to the controller and configured to receive an input from a user adjacent the barrier; an override input coupled to the controller for providing an override signal to the controller, the override input configured to receive and input from a switching device disposed externally from the device; and the controller coupled to a lock control device, the lock control device enables a barrier to be opened or closed, wherein upon receiving an output from the proximity detector that an object was detected, an input from the pushbutton changing from the open state to the closed state or the override signal from the override input, the controller activates the lock control device to enable the barrier to be open. ### Claim 2 (depends on 1) The device of claim 1, wherein the controller is coupled to the lock control device via a relay. ### Claim 3 (depends on 2) The device of claim 2, wherein the lock control device is at least one of a magnetic lock and/or a door strike. ### Claim 4 (depends on 2) The device of claim 2, wherein upon receiving the override signal from the override input, the controller activates the relay to enable the barrier to be open. ### Claim 5 (depends on 4) The device of claim 4, further comprising an indicator disposed on the face plate that indicates an operating state of the device, wherein the operating state includes a standby state, open state and/or override state. ### Claim 6 (depends on 1) The device of claim 1, further comprising an indicator disposed on the face plate that indicates an operating state of the device. ### Claim 7 (depends on 6) The device of claim 6, further comprising an audio output device that provides an audible indication that the barrier is enabled to be opened. ### Claim 8 (depends on 1) The device of claim 1, further comprising a communication module that enables two-way communication with an external device. ### Claim 9 (depends on 8) The device of claim 8, wherein the communication module operates by hardwire and/or wireless connectivity. ### Claim 10 (depends on 1) The device of claim 1, wherein the proximity detector is a passive infrared sensor. ### Claim 11 (depends on 1) The device of claim 1, further comprising an antimicrobial film disposed on the face plate and pushbutton. ### Claim 12 (depends on 1) The device of claim 1, further comprising a display and at least second and third pushbuttons coupled to the controller for programming the device. ### Claim 13 (depends on 12) The device of claim 12, wherein the display and at least second and third pushbuttons are disposed on a substrate coupled to the rear surface of the face plate. ### Claim 14 (depends on 1) The device of claim 1, wherein the proximity detector is a low-power radar-based sensor. ### Claim 15 (depends on 1) The device of claim 1, further comprising an indicator disposed on the face plate that indicates an operating state of the device, wherein the operating state includes a standby state, open state and override state. ### Claim 16 A device for controlling opening and closing of a barrier comprising: a face plate including a front surface and a rear surface, the face plate configured for mounting the device adjacent to the barrier; a proximity detector disposed on the front surface of the face plate that detects an object within a predetermined distance of the proximity detector, an output of the proximity detector controller; a pushbutton disposed on the front surface of the face plate having an open state and a closed state, the button coupled to the controller; and the controller coupled to an external lock control device, the lock control device enables the barrier to be opened or closed, wherein upon receiving an output from the proximity detector that an object was detected or an input from the pushbutton changing from the open state to the closed state, the controller activates the external lock control device to enable the barrier to be open, wherein the proximity detector is a doppler sensor, the doppler sensor determines a speed of the object, distance of object from the doppler sensor, an angle from object to the doppler sensor and a position of the object relative to the doppler sensor. ### Claim 17 (depends on 16) The device of claim 16, wherein a detection distance of the doppler sensor is adjustable. ### Claim 18 (depends on 16) The device of claim 16, further comprising a communication module that enables two-way communication with an external device. ### Claim 19 (depends on 1) The device of claim 1, wherein the pushbutton is further configured to interrupt power to the lock control device when depressed.
