Pulsar 9931-2 318 MHz Receiver and Two Transmitter Set
Product Overview
The Pulsar 9931-2SET packages a compatible 318 MHz receiver with two matching remote transmitters, giving installers a practical way to refresh an older radio-control setup as a matched system. Instead of trying to make an unknown old remote work with a questionable receiver, this kit lets the receiver and transmitters be coded together using the older trinary DIP-switch format. It is commonly used with compatible gates and garage door operators that need a single radio command input and have suitable 24 VAC/DC power available for the receiver. This is not an Open/Close/Stop receiver kit like the 831 family; it is a single-channel receiver/transmitter setup. It is also not a universal rolling-code conversion kit. Fitment depends on the operator control input, available power, and whether single-channel operation is the correct control method for that door or gate.
Compatible With
- Compatible Pulsar, Allstar, Allister, and Heddolf 318 MHz trinary DIP-switch systems
- Gate and garage door operators with a suitable single-channel radio input
- Older 931R, 9931R, ADX9931, and PDX9931 style receiver replacement applications where wiring and power match
- Single-button 9931T style transmitter applications using compatible coding
- Sites needing a matched receiver and two compatible remotes
- Not for Open/Close/Stop receiver replacement where an 831 OCS receiver is required

Technician Note
This set is for single-channel radio control. If the operator uses separate Open, Close, and Stop command inputs, compare with an 831 receiver and an OCS transmitter instead.
Before Ordering Checklist
- Confirm the operator can use a single-channel receiver input.
- Verify the installation has suitable 24 VAC/DC power for the receiver.
- Confirm the desired frequency is 318 MHz.
- Set the receiver and transmitters to matching trinary DIP-switch codes.
- Do not mix this set with unrelated rolling-code or different-frequency remotes.
Professional Advisory
Receiver wiring can involve low-voltage control circuits and, on 110V receiver models, line-voltage power. Use a qualified door or gate technician when voltage, relay wiring, operator terminals, or safety-device circuits are not clearly identified.
Product Questions and Answers
What comes in the 9931-2SET?
It is sold as a receiver and two matching remote transmitter set in common product listings.
Is this an Open/Close/Stop kit?
No. It is a single-channel receiver and transmitter set. Open/Close/Stop systems usually require the compatible 831 OCS receiver family.
What frequency does the set use?
The Pulsar 9931 family operates at 318 MHz on compatible trinary DIP-switch systems.
Which old model numbers are related to the 9931 family?
Common related references include 931R, 931T, 9931R, 9931T, ADX9931, and PDX9931, depending on the exact receiver or transmitter.
Can I use this to replace an unknown old receiver?
It may work if the operator has the correct power and single-channel control input. The wiring and voltage should be checked before installation.
