Pulsar Instruments Gate & Garage Remotes, Transmitters & Receivers
Pulsar Instruments products are used with compatible gate operators, garage door openers, and radio receiver systems where a replacement remote, transmitter, or receiver is needed. At Gate Openers Unlimited, this page helps customers find Pulsar remote controls, visor transmitters, multi-button transmitters, receiver and remote kits, DIP-switch radio controls, and related replacement access accessories.
When choosing a Pulsar product, start with the existing remote or receiver. The most important details are the frequency, model number, button count, DIP-switch format, receiver compatibility, and whether the system is being used on a gate opener, garage door opener, or access control receiver. A similar-looking remote may not work if the frequency or code format is different.
Pulsar Radio Control Products
Pulsar Instruments is commonly associated with older gate and garage door opener radio controls, especially replacement transmitters and receivers used with compatible Pulsar, Allstar, Allister, Challenger, and Heddolf-style systems. These products are often used when a customer needs to replace a lost remote, add an additional transmitter, or replace an older receiver setup without replacing the entire opener.
Many Pulsar-style controls are selected by frequency and DIP-switch format. Some common replacements are associated with 318 MHz systems, but the exact model still matters. Before ordering, verify the receiver, opener model, switch pattern, number of buttons, and whether the existing system uses binary or trinary code settings.

How to Choose the Right Pulsar Remote or Receiver
Start by opening the existing remote and checking the DIP switches, battery, and model label. If the old remote is missing, identify the receiver mounted near the gate opener, garage opener, or access control panel. The receiver information is often the best way to confirm the correct replacement remote.
- For replacement remotes: match the frequency, model number, number of buttons, DIP-switch count, and code format.
- For multi-button transmitters: confirm whether each button controls a separate opener, receiver channel, or open-close-stop function.
- For receiver kits: check receiver voltage, relay output, wiring, channel count, and the opener or gate controller input.
- For older systems: verify whether the replacement is intended for Pulsar, Allstar, Allister, Challenger, Heddolf, or a related compatible radio format.
- For unclear systems: replacing the receiver and transmitters together may be easier than trying to match an unknown older remote.
Before Ordering Pulsar Instruments Remotes or Receivers
- Confirm the model number printed on the existing Pulsar remote, transmitter, or receiver.
- Verify the operating frequency, commonly 318 MHz on many Pulsar-style replacement controls.
- Check the DIP-switch count and whether the switch format is binary or trinary.
- Match the number of buttons or channels needed for the gate, garage door, or access control device.
- Confirm whether the product is being used with a gate operator, garage door opener, receiver, or access control panel.
- For receiver kits, verify voltage, relay output, wiring, channel count, and mounting location.
- Do not assume compatibility based only on case color, button layout, or a similar-looking remote.
- If the old receiver information is unavailable, consider replacing the receiver and remotes as a matched set.
Pulsar Instruments Compatibility and Fitment Notes
Pulsar compatibility depends on the remote model, receiver model, frequency, DIP-switch format, coding style, button count, and opener or access control system being used. Two remotes may look similar but use different switch formats or receiver compatibility. A remote made for one 318 MHz system may still fail to work if the code format or receiver type does not match.
When replacing a Pulsar remote, copy the existing DIP-switch settings only after confirming the replacement has the correct frequency and switch format. When replacing a receiver, verify the power input, relay contacts, channel count, and whether it is wired to a gate operator, garage door opener, or access control panel.
If the receiver is installed inside a gate operator, garage opener, commercial access panel, or security control cabinet, have a qualified technician verify the wiring when needed. Do not bypass garage door photo eyes, gate safety devices, reversing edges, safety loops, access control wiring, or required entrapment protection.

Pulsar Instruments FAQ
What are Pulsar Instruments products used for?
Pulsar Instruments products are used for radio control of compatible gate openers, garage door openers, and access control receiver systems. Common products include remote transmitters, multi-button transmitters, receiver kits, and DIP-switch radio controls.
Are Pulsar remotes universal?
No. Pulsar remotes are not universal across all systems. Compatibility depends on frequency, DIP-switch format, coding style, receiver model, button count, and the opener or access control system being used.
What frequency do many Pulsar remotes use?
Many Pulsar-style replacement remotes are associated with 318 MHz radio systems, but the exact model still needs to be verified. Always match the receiver frequency and code format before ordering.
Can Pulsar remotes replace Allstar or Allister remotes?
Some Pulsar remotes may replace compatible Allstar, Allister, Challenger, or Heddolf-style remotes when the frequency, DIP-switch format, button count, and receiver compatibility match. Do not assume all models cross over automatically.
What is the difference between binary and trinary DIP-switch programming?
Binary DIP switches usually have two positions, while trinary DIP switches have three positions. The replacement remote must match the receiver’s expected code format. A trinary remote should not be replaced with a binary remote unless compatibility is confirmed.
How do I choose the correct Pulsar replacement remote?
Start with the model number on the existing remote or receiver. Then confirm the frequency, number of buttons, DIP-switch count, switch format, and whether the receiver is compatible with Pulsar, Allstar, Allister, Challenger, or Heddolf-style controls.
What should I check before replacing a Pulsar receiver?
Check receiver voltage, relay output, channel count, wiring, frequency, mounting location, and the opener or gate controller input. If the existing radio system is unclear, replacing the receiver and remotes together may be the cleaner option.
Why does my Pulsar remote not work?
A Pulsar remote may not work because of the wrong frequency, incorrect DIP-switch settings, incompatible code format, weak battery, damaged transmitter, receiver wiring issue, poor range, antenna problem, or a failed opener input. Check the remote and receiver before replacing parts.
