The Next Generation of
Commercial Door Operators
Gearhead Trolley (GT) style commercial door operators employ
lubricated gears and are optimal for heavy industrial, high-cycle
applications. Suspended from the ceiling, the operators are used on
sectional overhead doors with a standard lift. GT operators are directly
attached to drive and control the door.
Connectivity
• MyQ® Technology enables you to securely monitor and control your facility operator and lights with your smartphone, tablet or computer for greater peace of mind.
•
Alerts can be received as email or pop-up (push) notifications on a
mobile device, ensuring the status of your commercial door.
•
MyQ Mobile App is a free download with no annual activation fee.
Safety and Security
•
Security+ 2.0™ safeguards your facility – with every click, a new code
is sent to the commercial door operator so the door opens only for
you.
UL 325 requires all commercial door operators to be either constant
pressure to close or be equipped with a primary external monitored
entrapment protection device.

STANDARD FEATURES:
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.
DUAL VOLTAGE CONNECTIONS
Increase flexibility by enabling the installer to select the required voltage, within
phase, to meet job-site requirements.
Within phases, voltage is selectable at the time of installation with the
placement of a connector.
