WIRELESS OBSTACLE DETECTION FOR USE WITH DIFFERENT BARRIER OPERATOR TYPES

摘要

A wireless obstacle detection system includes a wireless obstacle sensor and a communication module designed to provide a retrofit solution for easily adding obstacle detection capabilities to a previously installed barrier operator system. To facilitate ease of installation, the communication module can communicate with a large variety of barrier operators including using at least two different protocols for communication with obstacle detectors. Such communication may be wireless or wired, depending on the barrier operator and communication protocol implemented by a particular previously installed barrier operator. Once configured to be able to communicate with a previously installed barrier operator, the communication module receives communications from the wireless obstacle detector about the presence or absence of an obstacle at or near the barrier and transmits a corresponding communication to the barrier operator using the correct protocol.
