Has anyone come across a company installing burglar alarms but not
requiring a maintenance agreement?

Printer ink, electric toothbrush head.... marketing syndrome!

I feel competent to do an annual walk test and routine battery change
but doubt my ability to organise the initial set up.

So far, I have arranged multicore cabling to likely detector points and
door button sets but stalled on finding someone to supply the kit and
get it going.
