Gearhead Sliding (GSD) style commercial door operators employ lubricated gears for heavy industrial, high cycle applications. GSD-style operators offer functionality that is similar to GT-style operators, but are used on single and bi-parting sliding doors.
SECURITY+ 2.0 RADIO RECEIVER
Standard on-board with Logic 5.0 operators.
Accepts up to (90) single-button or (30) 3-Button remote controls plus up to (30) wireless keypads or an unlimited number of DIP switch remotes.
MOTOR
Continuous-duty high-starting torque motor with instant reverse and overload protection.
Available in 1/2, 3/4, 1, 1-1/2 HP; single- or three-phase.
Capacitor start on single-phase.
Removable without affecting limit switch settings.
WIRING TYPE
Operators are factory preset to C2 wiring, providing momentary contact to open and stop, with constant contact to close.
Monitored entrapment protection, using approved photo sensors or sensing edges is optional, although recommended, when using C2, D1 or E2.
All other wiring types, B2, T, TS and FSTS can be selected with the addition of an appropriately monitored entrapment protection device (LiftMaster CPS-U photo eyes, LiftMaster OES monitored sensing edge, or a monitored sensing edge supported by the CPS-EI, as examples).
Logic 5.0 operators can only accept UL-Approved LiftMaster monitored entrapment protection devices.
