|Medium-Duty Gear-Reduced Jackshaft Operator for Rolling Grilles and Shutters –|
Model MGJ is a Medium-Duty Logic gear-reduced jackshaft operator for rolling grilles and shutters. It features a compact design, a floor level disconnect, a high-starting torque motor and a heavy-duty wormgear reducer.
MEDIUM-DUTY LOGIC TECHNOLOGY
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-RPEN4, 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.
Operator/Motor Control: Solid-state Medium-Duty circuit board.
Control Circuit: 24V NEC Class 2.
Floor Level Disconnect: Floor level disconnect provides emergency manual operation.
Drive Reduction: Heavy-duty wormgear-in-oil-bath speed reducer.
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.
Construction: NEMA 1 type electrical box with baked-on powder coat finish. Easily field converted for right or left mounting.
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.
Warranty: 2-year warranty.
CONTROL ACCESSORIES AND OPTIONS
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 protction or basic constant-pressure-to-close.
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.
