We have a customer that has a Tunstall nurse call system throughout the building and has smoke alarms linked into each speech unit in each flat, this is powered from the Tunstall unit and has back up battery in each smoke. would this be classed as a grade D fire alarm within the flats? I would argue not as they are not mans powered. if not what grade would this be classed?

I have a L3 system in the communal area of a block of flats. my question is does the electrical riser cupboards and water riser cupboards class as a room opening onto the escape route? and will need detection?

Does a HMO require a fire alarm zone plan if so would this fail a maintenance?, as I cannot find anything in the standards. only for commercial buildings.
