Hi,
one of our FB-V1 stopped beeping. We have checked the settings are correct, so it seems like the buzzer is dead.
Could you please give us part number of the specific buzzer used on board? We would like to exchange it and make it awesome again.

Hi Jan,
the V1 bridge uses this Buzzer: https://at.rs-online.com/web/p/piezo-signalgeber/7542084

Thank you!
Fortunately, it started working again – two magnets dislocated from the back side of the unit and got in touch with the buzzer. After removing them, it started working in 24 hours again.
