Abstract | An electronic push retraction exit device includes a support rail, a push rail and a latch mechanism having a latch bolt operably connected to the push rail and movable between latched and unlatched positions. A control circuit in the exit device drives a linear actuator to retract and hold the push rail and the latch bolt in the unlatched position. The linear actuator preferably includes a stepping motor and is connected to the push rail through a lost motion connection allowing the exit device to be mechanically operated without moving the linear actuator. The control circuit preferably includes an electrical adjustment for the retraction distance of the latch bolt and an adjustable relatch timer. The exit device may be operated by a remote switch attached to a control connection, which may be permanently closed to simulate a prior art electrically operated exit device for compatibility with third party control systems.
Un dispositivo de salida de retracción de empuje electrónico incluye un riel de soporte, un riel de empuje y un mecanismo de sujeción que tiene un perno de pestillo conectado operablemente al riel de empuje y movible entre posiciones sujetada y no sujetada. Un circuito de control en el dispositivo de salida impulsa un accionador lineal para retraer y retener el riel de empuje y el perno de pestillo en la posición no sujetada. El accionador lineal de preferencia incluye un motor de avance escalonado y está conectado al riel de empuje a través de una conexión de movimiento perdido que permite que el dispositivo de salida se opere mecánicamente sin mover el accionador lineal. El circuito de control de preferencia incluye un ajuste eléctrico para la distancia de retracción del perno de pestillo y un cronómetro de nueva sujeción ajustable. El dispositivo de salida se puede operar mediante un interruptor remoto fijado a una conexión de control, que puede estar permanentemente cerrado para simular un dispositivo de salida eléctricamente operado del ramo anterior para compatibilidad con sistema de control de tercera parte. |
