Texecom panel upgrade whilst keeping bellbox

[Leighton4412]

I’m planning to upgrade my Texecom Veritas R8 system to a Texecom Premier Elite 64W, retaining the existing Texecom bellbox.

Obviously the bellbox will be staying in situ, with just the control panel/keypads being changed for the new one. My concern is whether the bellbox will go off during this swap over.

I’ve read up about hold-off mode but I will be disconnecting all cables from the old panel including battery / mains power and the tamper connections for the bellbox. Will the hold off mode still work if all of these wires are disconnected, or will I need to do something else to avoid the siren going off whilst completing the work?

Thanks in advance

Just put the bellbox supply on the battery while you swop it over
