<p>The actuator has a carriage (6) with an arming stop (9), and an arming unit (10) connected to the carriage when the carriage is in arming position. An indexing lever (16) is carried by a case (1) and cooperated with the stop to retain the carriage in the arming position. A cross bar (15) is mounted in the case and cooperated with the lever to neutralize the lever and release the carriage. A control circuit has a detector detecting a course end position of the unit and carriage to control inverse movement of the unit and disintegrate the unit from the carriage. An independent claim is also included for a method of controlling a fire valve actuator.</p> |
