- kitchen extractor hoods, fire dampers, smoke vents, ventilation ducts,
- to activate water, foam, dry powder, CO2, or other gaseous fire extinguishing devices,
- to trigger devices for opening or closing windows, doors, roof hatches, hatches, machine- and belt stops,
- the triggering of special alarm or evacuation devices.
