Qualified OSDP readers
Pick a reader family in this list and the AC1 onboarding wizard runs end-to-end without extra steps. Older or unlisted readers will still work — they just need a manual V+ power-cycle mid-install to apply the new bus address.
Recommended — COMSET applies inline
These OSDP 2.x reader families apply a new bus address immediately when the controller sends a COMSET. The dealer install flow runs end-to-end as a single wizard with no power-cycle prompts.
| Family / model | OSDP version | Wiegand formats | Tested in our lab | Notes |
|---|---|---|---|---|
| WaveLynx Ethos | 2.2 | 26-bit, 34-bit, 40-bit | — | Vendor-confirmed inline. |
| HID Signo | 2.2 | 26-bit, 34-bit, 40-bit | — | Vendor-confirmed inline. |
| Farpointe Ranger | 2.2 | 26-bit, 34-bit | — | Vendor-confirmed inline. |
| Allegion Schlage (current firmware) | 2.2 | 26-bit, 34-bit | — | Older Schlage firmware is in the next table. |
Supported with caveats
These reader families work on the AC1 but COMSET behavior depends on the specific firmware running on the unit. The install wizard surfaces a "disconnect V+ for 2 seconds" step automatically — modern units skip past it, older ones actually need the cycle. Budget a few extra minutes per door.
| Family / model | OSDP version | Wiegand formats | Tested in our lab | Notes |
|---|---|---|---|---|
| Identiv uTrust 4500F | 2.x | 26-bit | Yes — 2026-05-30 | Inline COMSET worked once on our dev unit; subsequent COMSETs needed the V+ cycle. Plan for the cycle step. |
| HID iCLASS (older firmware) | 2.0 / pre-2.x | 26-bit | — | V+ power-cycle required per door. Allow ~30 seconds per reader during install. |
Honeywell / HHP family (OUI 00:06:8E) |
2.x | 26-bit | Yes — 2026-05-30 | Card-placement sweet spot is narrower than other families; coach end users on where to tap. |
Why some readers need a power-cycle
OSDP COMSET tells a reader its new RS-485 bus address. On modern 2.x reader firmware the address change takes effect on the next POLL — no install delay. On older iCLASS and pre-2.x hardware the new address is buffered until the next cold boot, so the only way to verify the change in-flow is to interrupt V+ for a couple of seconds. Software-controlled reader power isn't an industry norm (Mercury, HID, PDK, Brivo, and ICT all leave the cycle to the installer for UL and failure-surface reasons), so the wizard prompts for it and waits.
Adding a reader to this list
Bench-verifying a reader takes a few hours: COMSET round-trip, Wiegand format check, RS-485 termination + power-rail review, and a back-to-back swipe stress test. If you'd like a specific family added, contact our dealer team with the make, model, and firmware version.
