the fire alarm manual pull station in the picture is manufactured by the edwards company. the glass rod is a tamper indicator, nothing more. in order to reset this type of pull station, you need a small screwdriver. there is a scew slot on the top. a slight turn counter clockwise will allow the entire ffront of the pull station to swing down. on the silver back plane, there will be a toggle switch. if the station has been tripped, the switch will be up. push the switch to the down position. while the manual pull station is open, you can pull a small silver colored tab in, and on the front of the pull station slide in a new glass rod. once this is complete, simply swing the front of the pull station back up and snap it into place. this will allow you to reset the fire alarm panel.
