The last thing I wanted to do was upgrade seeing as it is only 6 years old. Out of curiosity how much would a similar one cost now?

Thanks, could you give me an example of a 12v PSU that would be suitable?

Had a Visonic Powermax Complete alarm system fitted back in 2014. This came with the MCS-740 wireless siren, but finding that the battery only lasts a maximum of 12 months and it is becoming expensive to replace every year.Wondering if it is the distance of the alarm panel from the siren or whether it is the 20 inch walls between the two that is causing the quick depletion of the battery?Thinking whether it would be worthwhile to go for a mains powered siren that would be compatible with the Powermax? I understand that there is a Visonic expander module that clips into the main alarm box for the cost of about £18, but what siren is compatible with it? Pictured are the new batteries ready to be fitted

All sorted now, set the system back to factory default.Re-enrolled everything including bell box. The system is now working fine, so could just have been a glitch.

So would you know what the S01 Tamper Open Error refers to on the MCS-740?

Fitted a new Visonic Powermaxcomplete to my house. Going through setting it up and have the status message S01 Tamper Open Error, relating I assume to the outside wireless siren, so unable to arm the system. Troubleshooting on the alarm manual states, "most likely the back tamper. Down power the siren and remove it from the wall, then adjust the screw on the back to extend the tamper alarm" Only screw on the back is the one that goes through the centre hole of the backplate for fixing, but notice that there is a gold coloured foil under the pcb near to this hole. Does the fixing screw pull the foil away from under the pcb or does it have to touch the pcb? Other two tampers on the siren seem fine. Siren is a Visonic MCS-740 wireless
