Patent attributes
A fire alarm pull station includes a cover which must be opened to reach a fire alarm actuating handle, and an audio pull station alarm triggered by opening the cover. Once triggered, the pull station alarm remains on until reset, which reset requires using a tool in a first embodiment or a key in a second (or key lock) embodiment. The tool or key preferably allows the pull station to be opened to reset the pull station alarm. The cover may further be blocked from closing after being opened, and may only be closed after opening the pull station to reset a blocking mechanism. The pull station alarm is preferably an audio alarm residing in the pull station and the pull station may be hard wired to the fire alarm or wireless. The presence of the pull station alarm serves to deter false alarm setting.
