Abstract: A door closer assembly for an entryway device having a position sensor that assists in determining the location of the door closer assembly, and thus the location of the associated entryway device, relative to at least an entryway. The position sensor can be coupled to, and/or part of, the door closer assembly. Information obtained by the position sensor may be used by one or processing devices of an access control system to determine whether the door closer assembly and/or the entryway device is at the closed location, among other locations, as well as the direction(s) of displacement of the entryway device. Such information may be utilized in calibrating other devices, as well as determining the occurrence of a number of events, including unauthorized displacement or holding of the entryway device. A timer may also be utilized to further evaluate the nature of the displacement of the entryway device.
