That seems an awful lot of money, we have one we did ourselves . Its a lay out of the floor indicating the fire panel zones we have 6 flats per block 3 ground floor and 3 1st floor. Each block has 3 alarm zones. so 1A,1B,1C. If any thing this would have shown up on your FRA that this wasn’t in place. I can send you a pic of what we have its very basic but does the job.
