As you may know, a manual pull-station is a manual fire alarm initiating device that is activated by pulling a lever. The pulling level can be designed to have a single-action mechanism or a dual-action mechanism. With most dual-action types, the user has to lift a cover or plate up firstly, then pull down on the lever, as a second motion.
