A system for signaling the position of a movable barrier includes a movable barrier; a motor coupled to the movable barrier for moving the movable barrier between limit positions; a position detection device that monitors the movable barrier to generate a barrier position signal; and an indication device that receives the barrier position signal and indicate a position of the movable barrier relative to the limit positions. The system also includes an operation mechanism for controlling the motor and at least one transmitter device which generates a transmission signal received by the operator mechanism to energize the motor. The system further includes a blocking switch which generates a blocking Signal received by the operator mechanism to prevent receipt of a transmission signal from a device other than one associated with the indication device.

L'invention concerne un système permettant de signaler la position d'une barrière mobile et comprenant une barrière mobile; un moteur couplé à la barrière mobile permettant de déplacer celle-ci entre des positions limites; un dispositif de détection de la position surveillant la barrière mobile de manière à produire un signal de position de la barrière; et un dispositif d'indication recevant le signal de position de la barrière et indiquant une position de la barrière mobile par rapport aux positions limites. Le système comprend également un mécanisme de fonctionnement permettant de commander le moteur et au moins un dispositif émetteur produisant un signal d'émission reçu par le mécanisme de fonctionnement, aux fins d'alimentation du moteur. Le système comprend également un commutateur de blocage produisant un signal de blocage reçu par le mécanisme de fonctionnement, de manière à empêcher la réception d'un signal d'émission provenant d'un autre dispositif que celui associé au dispositif d'indication.
