Quality Rolling Steel Doors
Alpine offers option NEMA certified push button and key control stations for all of our roll up doors, shutters and grilles. Details are below. Remote access controls can be found here.
Push Button Control Stations
Alpine’s Door Button Controls, and Three Button with Single Key Door Access Controls allows complete control of the door. These door controllers have ON/OFF key control with maintained key positions where the key is removable in either position. This allows the key holder to lock out the operation of the OPEN and CLOSE buttons. Below are Alpine’s door control buttons and door access controls.
Key Control Stations
Alpine’s Two-Position Key Controls and Two-Position Key Controls with Stop Button are equipped with a spring return. This forces the key position to center before key removal. These door controllers have stop door control buttons that allow you to halt the motion of the door at any point. Key control devices should only be used with operators wired for constant pressure. Below are examples of Alpine’s door access controls.
