M1XRF2H receives FF345 RF but M1 never changes zone

[Marshall Burchard]

I have:

• M1G firmware 5.3.36
• Original M1XRF2H (PCB Rev B, sticker 57-0044-00 RevA01)
• M1XRF2H firmware 0.9.8
• Genuine 2GIG FF345 manufactured 07/2025
• Wired 2nd-generation Nest Protect

The FF345 detects the Nest alarm correctly (red LED flashes in sync with the smoke alarm).

During the alarm:

• REC’D RF LED flashes.
• RXD LED flashes.
• Bus Stat is normal.

The transmitter is programmed in ElkRP with the correct serial number and I’ve tested Loops 1, 2 and 3. I’ve also tried two different wireless zone blocks.
Despite the receiver decoding the RF, the M1 never changes the zone state and nothing is logged in the event log.
Has anyone successfully used a 2GIG FF345 with the original M1XRF2H? Is newer receiver firmware or the v2 receiver required?
