A barrier operator feature enhancement device is designed to provide one or more features found in modern barrier operator devices and to incorporate those features into a previously installed barrier operator system. To facilitate ease of use, the barrier operator feature enhancement device can communicate with a large variety of barrier operators. Such communication may be wireless or wired, depending on the communication protocol implemented by a particular previously installed barrier operator. To facilitate the ease of installation, the device is designed to configure itself to operate with the communication protocol of the previously installed barrier operator. Once configured to be able to communicate with the previously installed barrier operator, the feature enhancement device works with the barrier operator to provide one or more additional features to enhance the capabilities of the previously installed barrier operator.

A management system for building equipment includes several units. An instruction transmission unit transmits an instruction to at least one device. A response reception unit receives a response indicating that a state transition is made by the device in accordance with the instruction. A detection unit detects an abnormal condition in which the response is not received by the reception unit within a reference time period after transmission of the instruction. A storage unit stores the reference time period. A time measurement unit measures a length of time from when the instruction is transmitted to when the response is received. A mode setting unit sets an operating mode of the management system to a reference-time-period calculation mode. A calculation unit performs calculations to determine the reference time period based on a measurement result obtained by the measurement unit, and prompts the storage unit to store the determined reference time period.
