Why this opener family gets a dedicated reference page
What separates a PCBA-engineered remote from a trading-company remote is one of the most common requests our B2B distributors receive, and one of the most common sources of return and refund cost when specified incorrectly. A buyer asking for a remote by brand name without identifying the model era ships the wrong part roughly 30% of the time. This page is the second opinion a warehouse manager runs before issuing a PO. It is not affiliated with the original manufacturer; it is an independent PCBA-engineering cross-reference compiled from current Gemu RF production SKUs.
Protocol generations in the installed base
The table below covers the protocol generations a distributor is most likely to encounter in the field. Frequency and code-rolling protocol rotate roughly every five years; specifying by brand alone is the most expensive mistake in the channel.
| Generation | Frequency | Code type | Typical install year |
|---|---|---|---|
| Pre-rolling era | Varies by region | Fixed / DIP | 1990s |
| First rolling | Varies by region | Rolling code (proprietary) | Early 2000s |
| Encrypted rolling | Varies by region | Rolling code (AES-class) | 2010s |
| Current generation | Varies by region | Encrypted rolling + dual-band | 2020–present |
Pairing sequence
- Press and release the learn button on the motor head. The adjacent LED lights for approximately 30 seconds.
- Within the 30-second window, press and hold the desired button on the replacement remote.
- The motor head LED blinks to confirm pairing, and the opener light flashes once.
- Test the button. If the opener does not respond, the remote is on the wrong frequency or wrong code generation — not defective.
Current Gemu RF replacement map
The table below maps the opener families to current production SKUs we ship. Each replacement is independently engineered PCBA, in a proprietary housing. We are not affiliated with the original manufacturer. Compatibility is on RF protocol and physical fit only.
| Opener family / model era | Frequency | Protocol | Compatible Gemu RF SKU | Pairing path |
|---|---|---|---|---|
| Current production SKUs, FCC/IC/RCM/CE-RED IDs, and case pack sizes are listed on the product pages and in the factory price list. MOQ for first distributor order is 500 pcs per SKU; case pack is 100 pcs. | ||||
Compliance marks required
Every remote shipped into the relevant market must carry the applicable compliance mark on the housing and in the user documentation:
- Australia: RCM (Regulatory Compliance Mark) registered to the factory in the ACMA database.
- United States: FCC Part 15 declaration. FCC ID must reference a current grant on fcc.gov.
- Canada: RSS-210 (Industry Canada) certification number alongside the FCC ID.
- Europe: CE-RED (Radio Equipment Directive 2014/53/EU) with a DoC held by the factory.
- All markets: RoHS compliance statement covering the six restricted substances.
Common pitfalls when sourcing
- Frequency mismatch from gray-market stock. A 433.92 MHz European remote sometimes lands in NA inventory through parallel import channels. It will not program to a 315 MHz opener, and the end customer returns it.
- Generation mismatch from generic spec. Specifying by brand alone without identifying the model era ships a first-rolling remote to a customer with an encrypted-rolling opener. The opener will not enter learn mode with the wrong-generation remote.
- Borrowed compliance marks. Distributors should request the FCC/IC/RCM/CE-RED certificate number, the registration holder (must be the factory), and the expiry date. Borrowed or expired registrations are a customs seizure risk.
Lead times and sampling
For distributors placing a first PO, we ship a 3-unit sample program with freight prepaid and respond to B2B inquiries within one business day with MOQ, lead time, and a sample Proforma Invoice. Standard lead time is 15 days for prototyping on a new SKU and 25–30 days for bulk production after sample approval. OEM private label (logo print on housing) is supported at a 1,000 pcs per SKU minimum.
Next step for distributors
If you are quoting a bulk order, request our compatibility pack — it contains the opener-to-SKU map for current and legacy models, the compliance mark evidence, and a sample Proforma Invoice. We respond within one business day.
