Motor: Powerful 1/2 HP, single phase motor with instant reverse and internal automatic reset thermal overload. Removable without affecting limit switch settings.

Wiring Type: All operators are factory preset to C2 wiring providing momentary contact to open and stop with constant contact to close. Momentary contact to close (B2 wiring) can be easily set. The operator is pre-wired to accept a sensing device, photoelectric control, radio controls and most types of access control equipment.

Control Accessories and Options:

Sensing Edges: (Recommended) Designed to sense an obstruction and signal door operator to stop or reverse as desired. Either an electric or pneumatic sensing device can be added to bottom edge of door.

Radio Control: Universal transmitters and receivers are available to signal the operator to open and/or close.

Emergency Egress Device: Attractive faceplate mounts flush to the wall and contains handle to disconnect operator from a grille, thereby allowing the grille to be opened manually or by spring tension.

Rolling Door Interlock Switch: Interlock switch disables the operator control circuit when a manual door lock is engaged preventing damage to the door and operator.

CPS® Commercial Protector System (Recommended): An inexpensive "non-contact" photo safety sensor designed to sense an obstruction and signal the door operator to reverse to open.
