Currently has none fire boards also do I need a smoke alarm on the entrance stairs

Hi thank you for replying so the apartment has interlinked smoke alarm and heat alarm off the lighting circuit. chip shop has a fire alarm system like Ctec fire system and double fire board on the ceiling which would be 60min fire or can we have ceiling tiles which are 60min fire approved in the chip shop in stead of pulling for all the current ceiling tiles and installing double fire boards

We have a chips shop with a 2 bedroom apartment on top, the apartment has its own side entrance through the alley way which also has a separate back door for the chip shop do I need a fire alarm system which inter connects to the apartment above using a repeater panel so many panel in the shop and repeater panel in the apartment zones loft unused - zone 1 Apartment - zone 2 chip shop - zone 3 basement unused - zone 4 or can I install domestic smoke alarm and heat alarm in the apartment and a Ctec fire alarm system in the chip shop
