The Patriot Telescopic Non-Contact SensingEdge
is manufactured to work with Rapid Roll and Sectional
Doors. The system consists of a Control Unit, Emitter
Eye and a Receiver Eye which simply mounts into a
rigid steel, spring loaded retracting arm. The arms
are mounted to the bottom of the door and extend
below the leading edge of the door, thus providing
an invisible infrared beam of protection. If the
beam is blocked by an object or person below the
door, the control unit signals the door operator
to stop and/or reverse. |
