Wide-spectrum smoke detector FDO221

Description

Standard (2):
The priority of the 'Standard' parameter set is set to robust response. It is therefore
particularly suited to use in rooms with few deceptive phenomena such as cigarette
smoke.
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.
