The Automatic 4-way connection or 4-way valves is an accessory provided upon request that allows you to:
- feed a second operator who will be equipped with an individual warning device signal on their mask;
- connect the self-contained breathing apparatus to an alternative source of air to prolong its autonomy and/or to
ensure a safe escape whenever the main feeding source has suffered an accidental interruption. When fed by an
alternative source (at 5.5 bar), the cylinder is automatically excluded.
The detailed instructions for use of the 4-way valve are attached to the accessory (instruction code 960040000).
