LiftMaster 02401 Indoor One-Button Control Station
The LiftMaster 02401 is a simple, rugged hardwired push-button station used when a commercial door operator needs a local START or OPEN command from an indoor wall location. It is commonly selected for facilities where a basic single-button command is enough and the operator already has the required control logic and safety devices in place.
This control station uses a die-cast metal surface-mount enclosure, so it can be installed without cutting a flush box into the wall. In a typical commercial operator setup, the button connects to the operator control terminals as a low-voltage, momentary dry-contact input. The exact door response is controlled by the operator wiring type, not by the button alone.
Correct fitment matters because the 02401 does not include a STOP button. On some operators it can be used as an OPEN-only station, while Type B2 control wiring may allow open/close sequencing. If the opening needs full open-close-stop control from the same location, choose an appropriate three-button or key-controlled station instead.
Compatible With
- LiftMaster commercial and industrial door operators that accept a hardwired dry-contact control station input, when wired according to the operator wiring diagram.
- Select LiftMaster commercial door operator families such as H, J, T, APT, GH, GT, SD, GSD, MJ, MH, MT, MHS, and MTS where the control-board terminal strip and control wiring type match the accessory function.
- OPEN or START input use on compatible LiftMaster operators.
- OPEN/CLOSE sequencing only on compatible operators with Type B2 control wiring.
- Indoor NEMA 1 locations where a surface-mount one-button station is acceptable.
- Not a substitute for a STOP button, emergency stop, monitored safety sensor, or entrapment protection device.

Technician Note
Use the 02401 only where a one-button command is appropriate. It does not provide a stop circuit, so do not rely on it as the only user control on an industrial door that requires a dedicated stop button.
Before Ordering Checklist
- Confirm the operator accepts a hardwired START or OPEN input.
- Verify whether the operator is wired for Type B2 operation if open/close sequencing is expected.
- Confirm the location is indoor and dry enough for a NEMA 1 station.
- Confirm a separate STOP control is installed where required.
- Match the part number to the job specification or operator accessory list.
Professional Advisory
Commercial door control wiring should be handled by a qualified door technician when there is any uncertainty about control type, stop circuit requirements, or safe door operation.
Product Questions and Answers
What does the LiftMaster 02401 button do?
It provides a momentary START command. Depending on the operator control wiring, the START input may open the door or cycle the door through open and close functions.
Can 02401 stop a moving commercial door?
No. This one-button station does not provide a dedicated STOP command. Use a separate stop station or a control station with STOP where required.
Is the 02401 for indoor or outdoor use?
It is an indoor NEMA 1 surface-mount station. It should not be used where a weather-resistant or washdown enclosure is required.
Will it work with every LiftMaster commercial operator?
It may be used with LiftMaster operators that accept the correct hardwired START or OPEN input. The actual function depends on the operator control wiring type.
Is this a wireless wall button?
No. The 02401 is a hardwired commercial control station, not a radio transmitter or residential wireless wall control.
