Disconnect power and follow LiftMaster service instructions before working inside the operator. Keep low-voltage wiring routed away from moving parts and sharp edges.
Do not bypass or disable alarm, fire access, photo eye, edge, or entrapment protection circuits.
Professional Advisory
Commercial slide gates require working safety and warning systems. If the alarm is sounding because of an entrapment, obstruction, or safety fault, repair the underlying issue before returning the gate to service.
