Thanks for the responses. Just to close this topic off:
1) The SAB was not in hold-off mode at time of original test given LED status and time elapsed since SAB fitted.
2) I went with my original assumption that wired terminals for SAB can't be used with a wireless bell and so disconnected...
Not tested at the time the device was registered with the panel (pre-installation). Panel was powered down for installation however the wireless SAB had not been powered down but installed 'as live'.
Only during full testing after installation did I find bell strobe not working.
Status...
Texecom Premier Elite 12W - Wireless SAB not working?
Anyone had this issue?
I learned the wireless SAB and successfully connected to panel (but not yet tested). I powered down panel to power up again when installed.
Added a sound bomb to usual bell terminals on PCB.
When testing...
