Table 2: Parameter sets for flame detector FDF241-9

Typical applications for parameter sets

Robust (01)
This parameter set is suited to halls where deceptive phenomena such as flying

sparks, molten metals or strong solar radiation can be expected. Examples:

Foundry, hardening shop, electric arc welding site, open ferry boat.
Universal (02)
This parameter set is suited to rooms where a normal fire growth can be expected.

Examples: Battery room, machine room on ships, transformer station.
Universal fast (03)
This parameter set is suited to rooms where a rapid fire growth can be expected

and there is a high danger to life. Example: Warehouse for chemicals.
Sensitive (04)
This parameter set is suited to large halls or outdoor applications where a normal

fire growth can be expected. Examples: Industrial storage room, print shop, wood

storage, atrium, recycling facility, ferry, cargo ship, tunnel.
Sensitive fast (05)
This parameter set is suited to halls and sites where a rapid fire growth can be

expected and where even the smallest of flames will result in major damage.

Examples: Fuel storage room, pumping station, petrochemical facility, aircraft

hangar.
Rapid (06)
This parameter set is suited to protection of physical assets. Small flames possibly

caused by processes must be detected immediately. The risk of false alarms is

accepted. Example: Conveyor belt transporting combustible products from a

furnace to the packaging area.
