MMTC PBS-3S Ouvre-Ferme-Arret Interior Control Station
The MMTC PBS-3S is an interior surface-mount three-button control station with Ouvre, Ferme, and Arret legends. These correspond to open, close, and stop wording for installations where French-language labels are preferred or required. It is part of the MMTC PBS interior control-station family and is typically used with commercial door or gate operator circuits that accept three-button command wiring.
This station is useful when the electrical function is the same as a standard OPEN-CLOSE-STOP station, but the job requires different button language. The housing is intended for indoor use, so it should not be placed outdoors or in wet areas unless it is installed in a properly rated enclosure approved for the application.
The PBS-3S should be matched by both part number and legends. It is not the same as PBS-3UDS, PBS-3FRS, exterior NEMA 4 units, or lockout stations. On replacement work, compare the original station, wiring diagram, and any site labeling requirements before ordering.
Compatible With
This product is commonly used with the following applications when the operator control circuit, wiring terminals, enclosure needs, and site layout match the part being replaced or added:
- Interior commercial door and gate operator circuits requiring Ouvre-Ferme-Arret button legends.
- Applications where OPEN-CLOSE-STOP control is needed but French-language labels are preferred or specified.
- Compatible operators with three-button momentary control station wiring.
- Replacement for matching PBS-3S installations with NEMA 1 surface-mount housing.
- Related PBS series stations where button function, language, and contact requirements are verified.
Because control stations and accessory devices are wired into the operator control circuit, verify the terminal labels, contact type, voltage rating, enclosure rating, and required command functions before ordering.

Technician Note
PBS-3S is selected when the button language matters. Electrically similar-looking stations may not satisfy the job if the required legends or site language standards are different.
Before Ordering Checklist
- Confirm that Ouvre-Ferme-Arret legends are required.
- Verify indoor NEMA 1 mounting is acceptable.
- Check the operator wiring diagram for three-button station wiring.
- Match the original station if replacing an existing control point.
- Confirm STOP circuit contact requirements before wiring.
Professional Advisory
Installation should follow the operator manufacturer's wiring diagram and all applicable safety requirements. Do not bypass stop circuits, monitored safety devices, entrapment protection, or required warning devices. If the operator uses high voltage wiring or the control circuit is not clearly identified, have the work performed by a qualified gate or commercial door technician.
Product Questions and Answers
What do the PBS-3S button labels mean?
Ouvre, Ferme, and Arret correspond to Open, Close, and Stop.
Is PBS-3S an exterior station?
No. It is an interior NEMA 1 surface-mount station unless installed in a separate rated enclosure approved for the job.
Can it replace a standard PBS-3 station?
Only if the wiring and label requirements match. The main difference is the button legend language.
What operators can use it?
Compatible commercial door and gate operators with three-button control terminals can use it when the wiring diagram supports the station.
Why does the exact label matter?
Labels help prevent operator confusion. On shared or regulated sites, the required control language should match the project or customer requirement.
