Fire detection and extinguishing control
Oxeo extinguishing systems are controlled and monitored through the tried and tested Minimax fire detection and extinguishing control technology. This ensures perfect compatibility, backed up by general approvals of electrical and mechanical system components. Unnecessary coordination costs and efforts or interface problems between different parts of the system are thus avoided. The extinguishing zones are continuously monitored by smoke, heat and/or flame detectors. In the event of a fire, these detectors transmit a signal to the FMZ 5000 fire detection and extinguishing control panel. The panel then activates the Oxeo extinguishing system and, in the case of multi-zone systems, the relevant selector valve. At the same time, it triggers an acoustic and optical alarm, which urges anyone present in the zone to leave the room affected, and simultaneously sends a signal to a permanently manned station. Once the individually defined pre-warning time expires, the actual extinguishing process starts. This means that the extinguishing gas is delivered to the extinguishing zone by means of the pipe network and emitted from the extinguishing nozzles thus extruding the oxygen from the source of the fire.
Extinguishing gas storage
The extinguishing agent is stored in high-pressure gas cylinders, which are then used in combination, enabling both the optimization of available space and extendibility of the Oxeo storage system. The filling pressure of every single cylinder is constantly monitored for leakage with pressure gauges and the results are displayed. Any error messages are transmitted to the fire detection and extinguishing control panel. This means that the quantity of available gas is constantly controlled. The quantity of extinguishing gas to be stocked depends on the fire hazard and the size and nature of the protected facility. The modular structure of the Oxeo storage system allows for perfect adaptation to the customer’s individual needs and local conditions and offers maximum flexibility, especially for system modification or extension.
Extinguishing zones and zone subvisions
A pipe network with Oxeo extinguishing nozzles runs through the protected area. The size of the pipe network and the overall arrangement of the extinguishing nozzles are determined by the respective risk. Oxeo fire extinguishing systems can be used as a single-zone system for the protection of one extinguishing area or as a multi-zone system for the protection of two or more extinguishing areas. Multi-zone systems are equipped with range valves which, in the event of a fire, only disperse the extinguishing agent in the affected extinguishing area. Individually controllable containers release a precise quantity of extinguishing agent tailored to the extinguishing area. As a result, separate fire extinguishing systems are not required. Extinguishing agent storage doesn’t exceed the amount required for the largest extinguishing zone in the system. In addition, the system can be easily adapted to building conversions. The quantity of fire extinguishing agent to be discharged and the flooding time determine the arrangement of the extinguishing nozzles and the complexity of the pipe network. Special design extinguishing nozzles make it easy to layout the pipe network.
