==12.1.1 Isolation Field Systems==
The Isolation Field System, or IFIS, was designed with the intent to isolate hostile alien forces that boarded the vessel for the crew. This function is considered vitally important when consideration is given to the fact that the Rosenanté class starship possesses a very small crew. The IFIS fundamentally isolates the threat through the use of perpetual containment fields, reinforced by miniature shield defenses for the IFIS emitter assembly. The IFIS is always active, limiting the mobility of non-authorized personnel,	securing sensitive sectors of the ship, and effectively hindering the process of any hostile aliens that may manage to board the vessel. The ship's computer monitors the movements of every official member of the ship's crew at all times. In this manner, the computer is able to activate or deactivate the IFIS screens on an individual basis as needed. This allows authorized crewmembers access to shipboard systems and compartments as needed. The IFIS consists of a series of Level 8 containment fields spaced an even 12.5-meters along the corridors of the vessel. In addition to these, an IFIS field also isolates each access portal and hatch. In the event that a commbadge should be captured, or fail, that badge is automatically removed from all access rosters, until security can investigate the occurrence.
As a benefit of the perpetually active IFIS fields, studies indicate that shipboard damage caused by fire and/or decompression was drastically reduced. The fields prevented large area decompression, and also limited the range of fire dispersion radically.
Although in larger compartments the IFIS system is not perpetual; all compartments are equipped with the capacity to further "compartmentalize" these large open areas. The computer is capable of assessing threats to the crew and equipment of the vessel, and can respond using the IFIS system, nearly instantly. The IFIS system was designed to operate independently of the ships main power supply when necessary. Each IFIS emitter and processor assembly is equipped with an independent high-yield Sodium Kelleride power system. This power cell is further treated with a Potassium Unified catalyst. This allows the production of oxygen as a by-product whenever the secondary power system is operated. This allows a crewmember to be compartmentalized in an otherwise decompressed area to survive asphyxiation and loss of pressure. This secondary power system will allow the full yield operation of the IFIS emitter in question for a period of 4 standard hours. Setting the emitter to a lower containment setting can extend this time.
