We just had Kidde out to look at one of our sites, 3 panels but all standalone, not much they could tell us other than at 8 years old and in a "high traffic" enviroment they had done well but are due for upgrade.
We changed the software about 4 years ago and this stopped a lot pf problems but they have slowly started to resurface.
The early probelms were caused by a few funny issues, the installer (not us) had run a flex behind the boards to route it to the mains block, when we took it out and fed it in the correct position so it didnt cross any boards it solved one issue.
2nd thing was the display and printer- the display has brightness levels, on max brightness and in fire with the printer running it caused the panel to crash, to much current draw, the printers apparantly take more current as they age, motor windings breaking down possibly and this can be enough to trip it over, easy fix is to disconnect the printer.
As for needing Kidde, well they didnt use any special software just had a visual inspection and listerned to our engineers talk about the system, we pretty much exhausted their tech helpline to no avail prior to having them attend site.
How new is new, if its under the magic year I am sure they would be pursuaded to visit site as a freebie
