Internal Security Standard IS-2171-177
Revision 12.3.2, Date 12/06/2171
CLASSIFICATION GAMMA / TOP SECRET SCI
This document establishes the Raven standards for physical security. There are four IS-2171-177 classes; Class 1 (lowest security) to Class 4 (highest security).
Components
Blast doors
Blast doors are specially designed, high-security doors which fulfil a critical role in isolating sections of facilities from each other and against outside intruders. They can protect against kinetic attack, explosives, and exotic or anomalous weaponry, depending on the class. They also protect against CBRN hazards, fires, and electromagnetic interference.
Classes
Class 1
Class 1 blast doors are required to feature high explosive and ballistic resistances, as well as an electronically actuated locking system with mechanical overrides rated to a high level of security. They must also be resistant to thermal lances and core drilling. They are not to be used at facility perimeters or sector firebreaks, but can be used in the interior of sectors for example as doors to individual rooms such as meeting rooms, server rooms or storage rooms where a high level of protection for that room is desired.
Class 2
Class 2 blast doors meet all the requirements of Class 1, but they are additionally required to incorporate anti-CBRN layering, integration with the facility's access control and alarming system, secondary magnetic locks to protect the main boltwork, and tamper protection of the mechanical override locks. They constitute the minimum class required at the external perimeter of Raven facilities (i.e. for entrance into Alpha or Delta areas).
Walls protecting Class 2 areas must incorporate seismic detectors designed to detect any attempts at penetration, signalling an alarm to the central security system to pinpoint the area of attack. They must be able to detect both kinetic and energy-based penetration attempts. An example of a Class 2 area is the Topside section of Black Mountain.
Class 3
Class 3 blast doors meet all the requirements of Class 2, but they are additionally required to feature an approved forcefield system, a breach prevention system with thermite sealing bolts, a full RF shielding, and hermetic seals for life support. The electronic viewport must incorporate an infohazard processor. They constitute the minimum class required for inter-sector checkpoints, as well as any point where a Delta or lower zone meets an Epsilon or higher zone.
Walls protecting Class 3 areas must incorporate forcefield projectors capable of fully covering the perimeter with no gaps and resist all attempts at penetrations, and a Penetration Detection System (PDS) mesh that immediately detects any attempts at intrusions into the protected area, in addition to the standard seismic detectors. The PDS must detect any intrusions greater than 10 picometres. Forcefield projectors must be fed from at least three independent power supplies with at least a 7-day backup power supply. Class 3 areas must also incorporate defences against manifold distortion that can be switched on in the event of an emergency. An example of a Class 3 area is the Descent section of Black Mountain.
Class 4
Class 4 blast doors meet all the requirements of Class 3, but they are additionally required to feature a dual-layer overlapping forcefield system and Class IV fractal armour plates. They must also utilise Pulse Electron Beam (PEB) countermeasure systems. They are required at any point of entry for a Sigma zone, as well as any area designated as Reality Critical (RC).
Walls protecting Class 4 areas must incorporate dual-layer overlapping forcefield projectors. The projectors must be capable of operating on a backup power supply completely independent from the outside world capable of running for up to ten years. Additionally, a particle-based interdiction system must be installed to provide complete coverage of the protected area. Class 4 areas must also incorporate continuously operational defences against manifold distortion, including grid control systems if justifiable. An example of a Class 4 area is the Sigma Unit and some high-security Black Research laboratories.
