smoke & heat detectors interlinked with co detector neccesarry?

Hi Guys 

My customer recently recieved a letter from St Andrews university regarding her property (a 2 bedroom ground floor flat) which is used for student accopmodation. My understamding is that a smoke detector in the hallway interlinked with a heat detector in the kitchen along with a standalone co detector would comply with current legislation ,however the letter stated "all alarms should be interlinked" .  I don't think the co detector needs to be interlinked  to the smokes . Look forward to hearing any of your opinions regarding this. thanks

p.s.  portion of letter attached

  • This subject came up in connexion with a new build last month. Householder didn't really want a smoke alarm in the sitting room 'cos puffing back from the fire might cause nuisance tripping. His memsahib and I won the day, albeit at the expense of extra work.


    CO alarms hadn't really been considered. AFAIK, they are required. My view is that in my draughty Edwardian home, CO is unlikely to build up, but that is far from the case in modern hermetically sealed (albeit with opening windows) homes. He still doesn't want them.


    If a CO alarm goes off, you evacuate the room +/- opening the windows. It seems to me that the threat is limited to the room, so I don't quite see the need to interlink them. That said, if I did have CO alarms in my house, I'd interlink all of them. Better to be safe than sorry. A nuisance trip is merely a nuisance; a failure to warn may be fatal! ?
