Heddolf P294-R 318 MHz Receiver Technical Details
The Heddolf P294-R is a 318 MHz fixed-code receiver using a 9-position, three-position trinary dip switch format. It is commonly used with Pulsar, Allstar, Allister, GTO, Mighty Mule, and compatible 318 MHz transmitter families.
The receiver output can wire into many operators as a relay input, but RF compatibility depends on the remote frequency and switch format. A 300 MHz Multi-Code remote or a rolling-code remote will not work with this 318 MHz trinary receiver.
Compatible With
- 318 MHz Pulsar, Allstar, Allister, GTO, and Mighty Mule style 9-position trinary transmitters
- Gate and garage door operators that accept a dry-contact relay input
- 12V or 24V AC/DC accessory power applications when the receiver is set correctly
- Replacement applications for older P294-K, P294-1KA, and P294-1KB style receiver references
- Not compatible with 300 MHz Multi-Code, 390 MHz Genie, LiftMaster Security+, or rolling-code transmitters

Technician Note
The receiver can be wired to many operator brands, but that does not make every remote compatible. The remote must match 318 MHz and the 9 three-position trinary code format.
Before Ordering
- Check the old receiver part number
- Confirm the handheld remote is 318 MHz trinary
- Match the 9 dip switch positions exactly
- Set the receiver voltage correctly before applying power
- Confirm whether the output should be momentary or maintained
Professional Advisory
Receiver wiring should be made to the proper low-voltage control input. Do not connect relay leads to line voltage or bypass gate safety circuits. Use a qualified technician when the operator wiring is not clearly identified.
Questions & Answers
What remotes work with the P294-R?
It is for compatible 318 MHz 9-position trinary transmitters such as Pulsar, Allstar, Allister, GTO, and Mighty Mule style remotes.
Is P294-R compatible with Multi-Code remotes?
No. Multi-Code style receivers are commonly 300 MHz and use a different coding format.
Can it operate any gate operator?
The relay output can wire to many operators that accept a dry contact, but the receiver must have the correct power and wiring.
How is the code programmed?
The code is set by matching the 9 three-position dip switches in the receiver to the compatible transmitter.
What older receiver numbers are related?
P294-K, P294-1KA, and P294-1KB are commonly referenced as related or replaced receiver numbers.
