[Ticket Question] Pcb Problem

[Secware]

On 6/4/16 I purchased an Accenta mini Gen4 and several other items from you to update an old alarm system I had in the house.

Installed the above and all worked fine. Yesterday I went to replace an old PIR and stupidly I forgot to power down the system first. Afterwards neither of RKP's or any of the PIR's worked, however the bell did. There is power to the PCB as the red light is on.

Is there anything I could check, or is it liable to be the end of the PCB?

Yours hopefully

I'd check the aux fuse in the panel first

Thanks for your response.  I have visually checked the four fuses I can see on the PCB (1A RKP,1A speaker, 1A bell/strobe and 1.6A battery), they all look ok, but will test them properly tomorrow.  Can't see an AUX fuse ?

It was the 1A speaker fuse, which looked ok but obviously was not.  System working ok now.

Good thanks for the follow up
