Thanks for the replies; the panel is fine as it's regularly maintained/walk tested and upgraded as needed (eg new sensors). Cheers, Brian

Hello, I'm searching for a new external sounder + strobe to work with a Paragon Plus wired alarm system, as the existing unit is faulty (the SAB module has died ) and to get into the box I'll have to butcher the cover as the new soffit is hard up against the cover so I can't remove it ? The Panel Spec. is as follows: BA: Negative Trigger B+: 12v supply B-: 0 volts BT Bell Tamper (-ve return) Max Current: 0.5A STB -ve: negative trigger STB +ve: 12v supply Max Current: 0.5A Is a Pyronix Deltabell a suitable option please, and if so which variant would be the one to go for - I notice there are Deltabell E, Plus and X on offer (have I missed any?) but am unsure of the difference between them (apart from price). Also, is there anything to be aware of regarding wiring? I installed and programmed the existing system myself so changing the box is fine - I just need a little guidance with a suitable unit as Alarm systems have moved on a little since the mid 90's.... Many thanks Brian
