Door closer diagnostics system

A door closer diagnostics system, comprising:

• a door closer secured to a door;
• a central processing device;
• and
• a data acquisition device comprising at least one motion sensor and at least one load cell, and wherein the data acquisition device is configured to (i) be mounted to the door, (ii) generate, by the at least one motion sensor, motion data indicative of motion of the door as the door is moved between an open position and a closed position, (iii) generate, by the at least one load cell, load data indicative of a force used to open the door from the closed position, and (iv) transmit the motion data and the load data to the central processing device;
• wherein the central processing device is configured to analyze the motion data to (i) determine a duration the door was in each of a plurality of door movement zones between the open position and the closed position, (ii) determine at least one adjustment to the door closer based on the duration the door was in each of the plurality of door movement zones, and (iii) provide at least a first installation instruction corresponding with the at least one adjustment;
• wherein the central processing device if further configured to analyze the load data to (i) determine the force used to open the door from the closed position, (ii) determine if the force used to open the door satisfies a predetermined criteria, (iii) determine, if the force used to open the door did not satisfy the predetermined criteria, at least one force adjustment to the door closer for adjusting the force required to open the door, and (iv) provide at least a second installation instruction corresponding with the at least one force adjustment;
• and
• wherein the central processing device is further configured to display the first installation instruction and the second installation instruction on a graphical user interface of the central processing device.

A method, comprising:

• mounting a data acquisition device to a door having a door closer;
• launching an application on a central processing device to record (1) motion data indicative of motion of the door generated by at least one sensor of the data acquisition device, and (2) load data indicative of a inputted mechanical force applied to open the door generated by at least one load cell of the data acquisition device;
• opening the door to an open position;
• releasing the door from the open position;
• and
• adjusting the door closer based on at least one installation instruction provided by the application in response to an analysis of at least one of (1) the motion data generated as the door moved from the open position to a closed position, and (2) the load data generated as the door was being opened.
