This may have been covered before but I cant find it, so I apologise now.
Detached ground and first block. 3 x small shop units on ground each with call points and own fire panel, two offices on first floor with own stair, and two separate flats with own entry stairs from fresh air, that were offices but have been converted to flats. They have fitted a Pt 6 mains and battery interlinked system in flats and fitted a part 1 system consisting of smoke detectors into the flat entrance hall (yes I am getting them to change it to heat) and smoke detection and call points in common stair to fresh air. (Not sure why unless the builders couldn't guarantee FR)
There is a new alarm panel at the base of the flats stairs for the part 1 system in flats and stairs. They have also linked all the other panels to this one as well.
Basically everything's linked to everything else. This is a 2018 conversion and this seems to be a pigs dinner of a set up for the alarm.
As there is currently no AFD in the commercial shops the false alarm risk is low. Bookies and a kitchen sales shop. Which was fine before the sleeping risk.
As there is now sleeping accommodation above the shops, unless 1 hour FR can be secured AFD should be fitted to warn those above as a compensatory measure. (shops are small low risk). I can already see problems with the management of the fire alarm and have voiced my concerns.
To help reduce false alarms (especially at night when the only people on site will be the flat occupiers) I want to recommend HEAT rather than smoke detection below the flats, as all guidance just say "detection" and doesn't specify heat or smoke?
Ceilings appear to be concrete slab but Im unsure of what services etc may have breached it.
Anyone see a problem with heat detection ?
