Neural fire detector FDOOT221
4.3.4.1
Description
Parameter sets:
Standard (2)
The parameter set is intended for robust response. It is particularly suited to
application in rooms where deceptive phenomena such as cigarette smoke or dust
can be expected.
Standard Plus (4)
The parameter set is fast and highly sensitive. It is particularly suited to application
in rooms without deceptive phenomena where the priority is on detecting the fire
early.
