All Star Garage Door — Wed, 20 Sep 2017 20:18:35 +0000

Industrial-Duty Hoist Operator

Hoist (H) style commercial door operators are optimal for industrial applications.

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.

LiftMaster Opener MH

All Star Garage Door — Wed, 20 Sep 2017 20:00:24 +0000

Medium-Duty Hoist Operator

Model MH is a Medium-Duty Logic hoist operator.

It features an adjustable friction clutch, a standard solenoid brake, a high-starting torque motor, a compact design and an emergency chain hoist with an electric interlock.

Extra Features

UL325-2010 compliant Medium-Duty Logic programmable integrated circuit board
Built-in 3-channel, 315MHz radio receiver accepts up to 20 Chamberlain® Security+® or unlimited DIP switch remotes.
3-button remotes can be programmed for OPEN/CLOSE/STOP operation
Programmable C2 or B2 wiring options (B2 requires CPS-U, CPS-UN4, or CPS-EI)
Integrated Timer-to-Close (TTC) allows programming from 5 to 60 seconds in 5-second increments. Allows for timed automatic door closure after the door reaches the full open position (Requires monitored safety devices, with CPS-U, CPS-UN4, or CPS-EI)
Integrated 90-second maximum run timer
UL325-2010 Monitored Entrapment Capability
Monitored protection against transient overvoltage conditions
3-button control station included

Standard Features

Motor: Powerful 1/2 HP, 115V single phase motor with instant reverse and internal automatic reset thermal overload. Removable without affecting limit switch settings.
Operator/Motor Control: Solid-state Medium-Duty circuit board.
Control Circuit: 24V NEC Class 2.
Emergency Manual Operation: Model MH provides easy emergency manual operation using a floor level disconnect and an electrically interlocked chain hoist mechanism.
Brake: Heavy-duty solenoid actuated brake standard.
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, but requires the presence of either CPS-U, CPS-UN4, or CPS-EI safety devices. The operator is pre-wired to accept a sensing device, photoelectric control, radio controls and most types of access control equipment.
Drive Reduction: First stage heavy-duty 4L V-belt; second and third stages #48 chain.
Bearings: Heavy-duty oil-filled bearings.
Push Button Station: 3-button station for OPEN/CLOSE/STOP functions is standard for all operators. Controls with 1, 2 and 3 buttons are available.

Radio Receiver: 315MHz radio receiver is integral to the Medium-Duty logic board. Accepts up to 20 Security+® remote controls and unlimited DIP switch remote controls.
Friction Clutch: Adjustable friction clutch helps protect against damage to the door and operator should the door meet an obstruction.
Warranty: 2-year warranty.

Control Accessories & Options

Primary Monitored Entrapment Protection: The presence of primary entrapment protection is required for all modes and features beyond basic constant-pressure-to-close performance. Primary entrapment protection devices are monitored continuously to insure safe operation of the door and limit door operator functionality should an obstruction be detected or in the event of device failure. LiftMaster Monitored Entrapment Protection devices, CPS-U, CPS-UN4 and CPS-EI, are designed to work in conjunction with LiftMaster commercial door operators to provide enhanced door safety and a broad range of modes and features to end users. Either monitored photo-sensor or monitored 4-wire sensing edge (in conjunction with the CPS-EI Edge Interface) protection may be selected, but one must be detected by the LiftMaster Logic 4.0 or Medium-Duty Logic circuit board in order to unlock full functionality.
Ancillary Entrapment Protection: (optional) LiftMaster Retro-Reflective Commercial Protector System® photo sensors, 2-wire non-monitored sensing edges and pneumatic sensing edges are considered secondary entrapment protection and may be used to supplement primary entrapment protection or basic constant-pressure-to-close.
Radio Control: Universal transmitters and receivers are available to signal the operator to open and/or close.
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.
Weather-tight Control Devices: A variety of weather-tight control devices are available including 3-button control stations, key control stations and digital keypads.
