V9 fault - SIREN WIRLS SUPERVN F1. Bell and sensors all new batteries. Will an upgrade kit from V9 to V11 pcb board fix the issue? Or faulty Siren module? Thanks in advance.
Hi yes it definitely was working after new batteries.
Also, twice someone been out n checked everything F1 Sirens cleared. Yet fault came back same day.
Do you think worth upgrading pcb to V11?
Or get a whole new system?
I would take the bell module out and bring it next to the control panel ( you could unplug the sounder and close the tamper switch with a zip tie ….see if you still get the supervision fault as it may be something blocking the signal to the bellbox …if this is the case replacing any parts is a waste of time untill you find out what is blocking it ..,
