Model LGO is a light-duty grille
jackshaft operator. It features a compact design, a high-starting torque
motor, an internal door lock sensor and a floor level disconnect, which
is ideal for emergency egress.

Door Lock Sensor:
The adjustable Door Lock Sensor
can detect if the door lock is engaged and will stop the operator eliminating
jamming and damage to the door or operator. There is no longer any need
for wiring guide-mounted interlocks.

station (included). D1 wiring is easily programmed and is designed to
accept the contact optional 2-button control station or 2-position keyed
control station for constant contact to open and close.
