Recently got a minerva 16e   not sure how you add or delete addresses on this panel ive been given a 6 digit code but cannot find anything to program this panel 

Iirc all done via pc, licence was an afternoon employee thing ?

A little late to the Party (as usual).

 

These were programmed/setup using a PC/Laptop - using Consys software developed by Thorn. Think they had a network system based around Windows NT, called "ThornNet" too - where panels could be networked around a site, and then connected to a computer in a main control room - running Windows NT and some Thorn developed bespoke software, that was often tailored to the site - as it would display zone maps and the like.

 

With the Panel - there was a 16E (as in photo) and a Minerva80 with 80odd zones - the installation data / text / addresses / zones / zoned sounder allocations and the like would be set up on the laptop and then uploaded into the panel.
Any changes later down the line would require an engineer with Laptop/Consys and a from memory, a Suitable data lead to make the changes.

 

Think these panels were introduced around 1991-3 - Thorn/ADT were still fitting them in 1999 and the software was only available to their own engineers.

 

That said, these panels also used a User Code to access certain functions, there was also an Engineers Code where you could access higher lever functions - not messed with one of these for 30something years, so can't remember if you can set stuff up on the panel via the Engineers Code and menus.
Think you need the Engineers Pass to connect a laptop for up/downloading anyway as it was a function buried within a menu.
