The Miller Edge AW14K500-18-RF is a non-monitored wireless Air-Wave edge system for select motorized commercial door applications. It combines an AW14-RF pneumatic transmitter switch, an MRF-01 receiver, and an 18-foot length of RAH-500 gum rubber hose.
When the RAH-500 hose is compressed, the resulting air-pressure wave travels through the connection tubing to the AW14-RF diaphragm switch. The integrated transmitter sends a wireless signal to the MRF-01 receiver, which changes its normally open relay output so the connected door operator can provide its programmed stop or reverse response.
The AW14K500-18-RF eliminates the moving coil cord or retracting reel normally used between a door-mounted sensing edge and the operator. The AW14-RF mounts on the moving door near the pneumatic edge, while the MRF-01 receiver remains wired to the operator control circuit.
The switch sensitivity is adjustable to accommodate the edge length and installation conditions. A pressure and temperature compensation valve helps the pneumatic system respond consistently as environmental conditions change.
AW14K500-18-RF is a non-monitored wireless edge system. It does not provide 10K resistance, pulsed monitoring, diode-capacitor monitoring, or proprietary supervised communication.
Miller Edge describes the AW14-RF-K10 system as ideal primarily for door operators manufactured before August 2010. It must not replace a required monitored sensing edge, monitored photo eye, or other approved entrapment-protection device on an operator that requires supervision.
Verify the operator manufacturer, complete model number, production date, control-board part number, edge-input function, receiver power, and current operator manual before ordering.
The MRF-01 provides a 2-wire normally open output for a compatible low-voltage edge, safety, or reversing input. When the receiver receives an activation message from the AW14-RF transmitter, it closes the relay contact.
A normally open terminal on an operator does not automatically confirm compatibility. The operator must permit a non-monitored dry-contact device for the intended safety or control function.
Metal door sections, operator cabinets, structural steel, nearby radio equipment, antenna placement, and lack of clear line of sight can reduce the actual operating range.

Mounting screws for the AW14-RF transmitter and MRF-01 receiver are not listed as included. Operator wiring accessories, sensing-edge extrusion, mounting channel, junction boxes, tools, and additional safety devices are also not confirmed as included.
The MRF-01 antenna wire must remain visible to the transmitter and should not be placed behind metal. The receiver should be mounted near the operator so its integral wiring reaches the control terminals without placing the antenna inside a shielded metal location.
The RAH-500 hose, P-50 plug, P-50H plug, connecting tubing, and barbed fitting must remain airtight. A split hose, leaking plug, loose connector, blocked tube, or incorrect sensitivity adjustment can cause missed activations or nuisance reversals.
Longer pneumatic edges generally require greater switch sensitivity. Excessive sensitivity can allow door vibration to cause unwanted activations.
Installation, receiver wiring, transmitter programming, sensitivity adjustment, pneumatic assembly, and final testing must follow the current Miller Edge instructions, operator manufacturer manual, applicable electrical codes, and current commercial door safety requirements.
Never use this non-monitored system to bypass a monitored safety input, jumper an entrapment-protection circuit, or conceal a sensing-edge fault. Do not connect the receiver output directly to a motor or an unsuitable line-voltage circuit.
A qualified commercial door, garage door, low-voltage, or industrial-controls technician should complete the work when the receiver voltage, operator input, RF placement, pneumatic assembly, or required safety response is unclear.
The kit includes an AW14-RF wireless Air-Wave transmitter/switch, MRF-01 receiver, CR2032 lithium battery, 18 feet of RAH-500 hose, P-50 closed plug, P-50H plug with hole, and 218-27-18 barbed connector.
No. It is a non-monitored wireless Air-Wave system and must not replace a monitored entrapment-protection device when the operator requires one.
The MRF-01 provides a 2-wire normally open relay output for a compatible low-voltage edge or safety input.
The system has a 50-foot nominal range and may operate up to 100 feet under optimal conditions. Metal obstructions, antenna placement, and radio interference can reduce actual range.
The transmitter uses one CR2032 3V lithium coin-cell battery. The documented kit includes one battery.
Yes. Miller Edge instructions state that up to eight compatible transmitters can be programmed to one MRF-01 receiver.
No. It refers to the supplied RAH-500 gum rubber hose length. The wireless range is 50 feet nominal and up to 100 feet under optimal conditions.
No. The operator must permit a non-monitored normally open edge input and provide compatible receiver power. Verify the operator model, manufacture date, control board, and current manual before ordering.
