A little bit of confusion:
For Risk Group WB, < 100 occupants and escape height of < 4m - the table requires a Type 2 system, however note 1c “system not required” has potential to be applied
[For risk groups WB, in single level buildings with a storage height is less than 3.0 m and the escape route serves no more than 50 people.]
This is a change from amendment 2, table 2.2c.
The only possible logical conclusion I can apply here is, that this reference could only relate to a single storied building with limited area intermediate floor - hence the escape height.
e.g. workshop/factory/manufacturing
Otherwise, where storage height exceeds 3m a Type 3 system is required.
Or:
a) is there some other building configuration I am missing ?
b) simple error in the table ?
c) requires MBIE comment/clarification ?
suggestions welcome
