Title: ADB Vol 1 fire detection
Post by: xan on November 20, 2008, 05:21:57 PM

For large dwelling houses, of 2 storeys,it recommends a grade B LD3 system. A grade 'B' system is decribed as one that comprises of fire detectors 'other than smoke and heat alarms'.Why is this?I don't understand why it is recommending a system that does not have smoke/ heat detectors, when other sizes of dwellings(bigger and smaller) have smoke/heat detectors.
Is it a misprint,or can someone please explain.

because smoke and heat alarms are not the same as smoke and heat detectors.

  ??? if you meant to say that they are not the same,it would now make sense! i.e. a smoke or heat 'detector' does not have an alarm(sounder) fitted in it,a smoke/heat alarm does.
If not please explain a bit more.
