Pulsar 9931-1SET 318 MHz Receiver and Transmitter Set, 9 Dip Switch
The Pulsar 9931-1SET is a receiver-and-remote package for 318 MHz single-channel access control. It is intended for older style gate and garage door applications where a simple open/close radio command is needed and the site is using trinary dip-switch coding instead of modern rolling-code radio technology.
For a parts counter or field technician, the important details are the 318 MHz frequency, the 8 dip-switch trinary code format on the transmitter, and the 9 dip-switch / 3-prong style single-channel receiver family. This set is commonly ordered when a customer wants the receiver and matching remote together rather than trying to match one new part to an unknown older radio. It is not the same as an Open/Close/Stop Pulsar 831 receiver system, and it should not be used to replace unrelated 300 MHz, 310 MHz, 315 MHz, 390 MHz, 433 MHz, or rolling-code receivers.
Compatible With
Commonly associated with the following radio families and applications when the receiver voltage, connection, and coding format match:
- Pulsar 9931R single-channel receiver family
- Pulsar 9931T transmitter family
- Pulsar 9931-1 receiver and one transmitter set
- Pulsar 9931-2 receiver and two transmitter set
- Allstar / Allister 318 MHz trinary dip-switch systems
- Heddolf 318 MHz trinary dip-switch systems
- ADX9931 and PDX9931 related receiver references
- Select gate operators using a compatible 24 VAC/DC radio input
- Select garage door operators using a compatible external receiver input
- Single-channel open/close command applications, not Open/Close/Stop commercial stations

Technician Note
Use this set when both the receiver and the remote need to be replaced as a matched pair. If the customer only needs an extra remote for an existing working receiver, the 9931T transmitter may be the better part. If the existing system has dedicated Open, Close, and Stop buttons, look at the Pulsar 831 style receiver and compatible OCS transmitters instead.
Before Ordering
- Confirm the existing radio system is 318 MHz
- Confirm the site uses dip-switch trinary coding, not rolling code
- Confirm the receiver power available is 24 VAC/DC
- Confirm the receiver connection style and available operator input
- Do not use this as a replacement for Pulsar 831 Open/Close/Stop receivers
Professional Advisory
Programming a transmitter is normally low-voltage work, but the receiver and operator controls may be inside a powered control box. Do not bypass safety devices or open high-voltage compartments unless you are trained and qualified.
Important Ordering Warnings
The 9931 single-channel family and the 831 Open/Close/Stop family are different radio-control layouts. Matching only the Pulsar name is not enough; frequency, button function, receiver voltage, and coding format must all match.
Product Questions and Answers
Is the Pulsar 9931-1SET a receiver and remote together?
Yes. It is a set that includes a compatible receiver and one transmitter for a 318 MHz single-channel dip-switch radio application.
Will this work with my old Allstar or Allister remote system?
It may be used with select Allstar, Allister, Pulsar, and Heddolf 318 MHz trinary dip-switch systems when the receiver voltage and connection style match.
Is this the same as a Pulsar 831 Open/Close/Stop receiver?
No. The 9931 family is a single-channel receiver and remote setup. The 831 family is used for commercial Open, Close, and Stop functions.
How is the transmitter programmed?
The transmitter code is set by dip switches. The receiver and transmitter must be set to the same compatible trinary code pattern.
Can I use this with a rolling-code opener?
No. This is for compatible 318 MHz dip-switch style systems, not modern rolling-code receiver systems unless an external compatible receiver is intentionally wired to the operator.
