A wall control unit (60) for a movable barrier operator (10) sends baseband signals over a wire connection (62) to a head unit (24) of a movable barrier operator to command the movable barrier toperform barrier operator functions. The wall control unit (60) has a wall control unit port for connection to the wire connection (62). A first switch (122) sends a barrier command signal to the head unit (24) commanding the head unit (24) to open or close a movable barrier (16). A second switch (120) commands the head unit (24) to provide energization to a light source (72). An infrared detector (78) causes a command signal to be sent to the head unit (24) to control the illumination state of the light source (72).

L'invention concerne une unité de commande de paroi (60) destinée à un mécanisme (10) de commande pour fermeture mobile. Cette unité de commande de paroi (60) envoie des signaux de bande de base au moyen d'une liaison par fil (62) à une unité de tête (24) d'un mécanisme (10) de commande pour fermeture mobile, lequel mécanisme peut commander plusieurs fonctions de ladite fermeture mobile. Cette unité de commande de paroi (60) comporte un port permettant d'effectuer la liaison par fil (62). Un premier commutateur (122) envoie un signal de commande de fermeture à l'unité de tête (24) afin d'ouvrir ou de fermer une fermeture mobile (16). Un second commutateur (120) commande l'unité de tête (24) afin de mettre une source de lumière (72) sous tension. Grâce à un détecteur infrarouge (78), un signal de commande est envoyé à l'unité de tête (24) pour contrôler l'état d'éclairage de la source de lumière (72).
