Between 1 K/min and 10 K/min, this value increases by a few degrees.
All parameter sets meet the criteria of standard EN 54-7.
4.3 Smoke detector
The optical smoke detector OP720 demonstrates quick response behavior in the
event of slow-burning fires that generate smoke. It is extremely well suited to
general-purpose applications.
The optical smoke detector OP720 has two parameter sets available for selection.
4.3.1 Parameter sets
(Parameter set numbers and comments in brackets)
Standard (1/Default):
For standard applications, such as in corridors, bedrooms, offices, and living
rooms.
Sensitive (2):
For areas with few misleading sources of false alarms, such as cigarette smoke,
exhaust fumes, and steam.
The procedure for setting the parameter set via the control panel is described in
the control panel documentation.
