Thanks both for the replies, helped alot ?

Thanks Tom I thought that may be the case, jut a bit of wishful hoping on my part.

Morning I have a small office building on site which is around 60 sqm with 2 floors, 5 offices a kitchen and external boiler room. Normally there will be 4 office staff in the building who are all familiar with the lay out which has 1 exit. My question is do I need to install some kind of fire alarm system or would hardwired interlinked smoke alarms suffice? Thanks in advance.
