The MZ-1 is the modular control unit within the Oxeo multi-zone system, and is used for ensuring the correct amount of extinguishant is deployed to the correct extinguishing zone. These quantities can be adjusted to fulfill the design requirements of each extinguishing zone. A maximum of 10 zones can be protected with the accompanying 5 extinguishing quantities. The control unit is intended for the use in IG-01 and IG-100 fire extinguishing systems. The MZ-1 controls all pneumatic system components via control gas from a pilot cylinder.
