Think some of the issues may be:
1 Most important of all if the alarms go off you must dial 999 immediately before you look to see if there is a a fire or not. This must be part of the owners written fire procedure and must be followed at all times. Failure to do so will be considered as reckless and negligent behaviour and would lead to prosecution.
2 Storage cupboards should not be situated off bedroom accommodation and must have integral fire detection and be kept locked shut at all times if not in use
3 Fire brigades must not charge for attendaning any fire alarm request, whether there is a fire or for a false alarm
4 swingfree doors as standard for all bedrooms
5 improved inspection of care homes by appointment of fire prevention officers to Care Commission (or a separate national fire service section just for care homes)
6 mandatory minimum training for night staff, owners and registered managers to deal with small fires/raising alarm/evacuation as well as other staff
7 Central fire alarm panels locate fires not just to an area but to the precise location ie exact room or cupboard
NB Installation of sprinklers should reduce insurance premiums substantially as did so in USA
