摘要：A remote unit (14) couples to an obstacle detection sensor (13) to both detect an obstacle in the path of a movable barrier (11) and operability of the obstacle detection sensor (13) itself. Information regarding these and, optionally, other parameters (such as battery status) is coded and transmitted as a short burst wireless transmission to an interface unit (15). The interface unit (15) decodes the message and provides controlling information to a movable barrier operator (12) as appropriate when an obstacle is present, when the sensor (13) is faulty, or when other monitored parameters are out of normal bounds. In addition, the interface unit (15) can provide local alarms (auditory and visual) when detecting one or more of the above conditions.
