The Oxeo disable device MX prevents the release of the extinguishing agent to the extinguishing area by means of a manually operated lever. When the system can be activated unintentionally or people are unable to leave the extinguishing area within the egress time (i.e. for repair or maintenance work), the disable device acts as a non-electrical blocking device that prevents the extinguishing agent from being released. The limit switches attached to the Oxeo disable device are lab approved for field wiring. Limit switches are not available for separate purchase. The Oxeo disable device hardware comes fully assembled
