Neural fire detector FDOOT221

Description

Standard (2):
The priority of the 'Standard' parameter set is set to robust response. It is thus
particularly suited to application in rooms where deceptive phenomena such as
cigarette smoke or dust can be expected.
Standard Plus (4):
This parameter set is fast and highly sensitive. It is thus especially suited to rooms
without deceptive phenomena, where the priority is on early fire detection.
