Liftmaster 658206 Exter Pneu Treadle Kit

LiftMaster 658206 Exterior Pneumatic Treadle Kit

The LiftMaster 658206 exterior pneumatic treadle kit is designed for vehicle activation at commercial doors and controlled access openings. When a vehicle drives over the hose, the air pulse operates the switch and sends a signal to the connected operator control circuit.

This kit is often selected where cutting a loop into pavement is not practical or where a simple above-ground vehicle treadle is preferred. It is not intended to replace monitored entrapment protection or pedestrian safety devices.

Compatibility and Application Notes

• Commonly used with compatible LiftMaster commercial door operators and control stations that accept a 2-wire switch input.
• May be used as an OPEN control on many operator setups when the input and control logic are correct.
• May be used as a SAFETY input on select older operator wiring types such as B2, C2, T, T1, or TS when the operator documentation allows it.
• Designed for vehicle-actuated applications using a pneumatic treadle hose.
• Not a complete safety system and not a replacement for photo eyes, sensing edges, or code-required monitored protection.

Technician Note

A pneumatic treadle should be positioned where only intended vehicles cross it. Poor hose placement can create nuisance operation, missed activation, or unsafe traffic flow around the door.

Before Ordering

• Confirm the operator input is suitable for a treadle switch signal.
• Confirm the application is vehicle activation, not pedestrian protection.
• Confirm the hose length and enclosure location work for the driveway or door approach.
• Confirm the site environment requires an outdoor-rated enclosure.
• Confirm required door safety devices remain installed and functional.

Professional Advisory

A qualified commercial door technician should verify the operator control wiring before connecting a treadle kit. Do not wire a treadle in a way that bypasses monitored safety protection or creates automatic movement without proper safeguards.

Product Questions & Answers

What comes with the 658206 treadle kit?

The kit includes the outdoor NEMA 4/12 enclosure, 10 ft. signal hose, outdoor air switch, and hose plug.

Does this pneumatic treadle need power?

The treadle switch itself does not require power to function, but it must be connected to a compatible operator control input.

Is this the same as an in-ground loop detector?

No. A pneumatic treadle is an above-ground hose-style vehicle activator. A loop detector uses wire installed in the pavement and a loop detector module.

Can this be used as a safety device?

Only use it for a safety input when the operator wiring type and installation instructions specifically allow that function. It does not replace required monitored photo eyes or sensing edges.

Why would a treadle kit fail to activate the operator?

Common causes include a damaged hose, loose hose plug, failed air switch, incorrect wiring, or connection to the wrong operator input.
