Single Pull Switch Control
Hazardous Area Overhead Mt. (NEMA 7/9)
Die cast hazardous area enclosure
May be used in two different ways: as an OPEN only control (all LiftMaster operators) or as an OPEN/CLOSE control (only LiftMaster operators with types B2 and S2 control wiring). In the latter case, pulling the cord will open a fully closed door, close a fully opened door, and reverse a closing door. Pulling the cord whlie the door is opening will either have no effect (type B2 wiring) or will stop the door (Solid State Logic Control Board).
WARNING: When used on most industrial operators, this control will not stop the door. Use another control that has a STOP button in conjunction with this control.
