Rugged credential input assemblies

An access control device, comprising:

• a mounting plate;
• a pivot pad pivotably mounted to the mounting plate, wherein the pivot pad is biased to a home position and is operable to pivot to each of a plurality of pivoted positions;
• a sensor mounted to the pivot pad such that the sensor moves with the pivot pad, wherein the sensor is configured to generate information relating to an orientation of the sensor;
• a user input device operable to move the pivot pad from the home position to each of the plurality of pivoted positions, thereby altering the orientation of the sensor;
• a controller in communication with the sensor, wherein the controller is configured to determine an inputted code based upon information received from the sensor, to compare the inputted code to an authorized code, and to issue an unlock command in response to the comparing;
• and
• an electronic actuator in communication with the controller, wherein the electronic actuator is configured to transition the access control device from a locked state to an unlocked state in response to the unlock command.

A keypad assembly, comprising:

• a housing;
• a pipe mounted in the housing, the pipe including a plurality of apertures;
• a speaker mounted in the housing and configured to emit a sound into the pipe;
• a sensor mounted in the housing, the sensor including at least one microphone operable to detect sound;
• a plurality of keys movably mounted to the housing, wherein each key is associated with a corresponding and respective aperture of the plurality of apertures and is movable between a first position in which the corresponding and respective aperture is closed and a second position in which the corresponding and respective aperture is open to thereby modulate the sound detected by the sensor;
• and
• a controller in communication with the sensor, wherein the controller is configured to determine an inputted code based upon information received from the sensor, to compare the inputted code to an authorized code, and to issue a command in response to the comparing.
