H-style operators include a floor level chain hoist to ease manual operation in an emergency or power outage.
The operators are typically mounted to the wall when used with larger sectional overhead doors with vertical or high lift and mounted to the wall or the front of the hood when used with rolling doors and grilles.
H operators are attached to the door jackshaft to indirectly drive the door.
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.
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.
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).
