Miller Edge AW14K500-18-RF Wireless Air-Wave System Details
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.
What This Wireless Air-Wave Kit Does
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.

Commonly Associated Applications
- Select motorized commercial doors
- Air-Wave configured sensing-edge applications

- Cold or high-vibration environments where a pneumatic edge is appropriate
- Additional detection where permitted by the operator manufacturer
Important Non-Monitored Device Warning
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.
MRF-01 Receiver Output
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.
Wireless Range and Transmitter Capacity
- Nominal range: 50 feet
- Maximum range: Up to 100 feet under optimal conditions
- Receiver capacity: Up to eight compatible transmitters
- Radio frequency: 915 MHz with FSK modulation
- Response time: Approximately 100 milliseconds from edge activation to receiver relay output
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.

Not Intended For
- Replacing a required monitored sensing edge
- Operators requiring 10K, pulsed, or diode-capacitor monitoring
- Direct connection to a motor or line-voltage load
- Applications requiring a normally closed receiver output
- Gate operator use without documented manufacturer approval
- Replacement based only on matching frequency or enclosure appearance
- Installations where the receiver antenna must remain behind metal
Technician Note
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.
Before Ordering Checklist
- Record the door operator manufacturer and complete model number.
- Identify the operator manufacture date and control-board part number.
- Confirm that the operator permits a non-monitored normally open edge input.
- Verify the exact MRF-01 receiver power requirement from its current label.
- Confirm that an 18-foot RAH-500 hose is appropriate for the door.
- Verify that the complete pneumatic path can remain airtight.
- Check the transmitter-to-receiver distance and RF line of sight.
- Confirm that the receiver antenna will not be shielded by metal.
- Determine whether additional transmitter or receiver mounting screws are required.
- Confirm that all required monitored entrapment-protection devices remain installed.
Installation and Safety Advisory
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.
