Standard (2):
The priority of the 'Standard' parameter set is set to robust response. It is thus
particularly suited to application in rooms where few deceptive phenomena such as
cigarette smoke can be expected.
Standard Plus (3):
This parameter set is both fast and sensitive. It is thus especially suited to rooms
without deceptive phenomena, where the priority is on early fire detection.
