{{quote|Unfortunately, my usefulness to this particular endeavor has come to an end. [[Containment protocol|Protocol]] does not allow units with [[Monitor|my classification]] to... perform a task as important as the reunification of the [[Activation Index|Index]] with [[the Core]]. That final step is reserved for [[John-117|you]], [[Reclaimer]].|[[343 Guilty Spark]]}}

Inside there was a large circular [[Bridge (structure)|bridge]] that lacked supports. The bridge ended in a circular walkway. Both the bridge and walkway were made out of a reflective, transparent material. In the center of the walkway there was a hologram of [[Threshold]], [[Basis]], and the ring between the two.<ref name="Halo: The Flood">'''[[Halo: The Flood]]''', ''pages 192-193''</ref> On the outside of the walkway there was a model of the Halo ring itself. The model displayed a detailed map of the terrain and slowly rotated.{{Ref/Reuse|Halo: The Flood}}

The chamber contained [[the Core]], a [[Holography|holographic]] computer terminal where the [[Activation Index]] could be inserted to activate the rings. The terminal also reported the weather, rate of spin, information on the machines keeping the ring running, and information on the outbreak of the [[Flood]].<ref name="Halo: The Flood V2">'''[[Halo: The Flood]]''', ''pages 254-255''</ref>

===Installation 08===

The control room for the [[Installation 08|replacement Alpha Halo]] constructed at [[Installation 00|the Ark]] is a nearly identical copy of the original ring's counterpart. The temple structure has the same basic triangular shape as Installation 04's control room, with a long support beam running from the ground to the top of the structure. There are minor aesthetic differences, including the walkways on each level being more narrow, as well as the tower at the top being replaced by a large flat landing.<ref name="hh3">'''Halo 3''', campaign level ''[[Halo (Halo 3 level)|Halo]]''</ref>

Inside the control room, the corridors and doorways are reminiscent of Installation 04, while offering minimal changes. The actual control room and control panel is scarcely different from the original. The large dome-shaped room still shows a holographic image of the Halo ring, although Threshold is missing from this image (as the ring has not been moved to that point).{{Ref/Reuse|hh3}}

The differences in design from the original Alpha Halo may be due to the ring's incomplete state, as suggested by Cortana's observation, "Halo. It's so new...unfinished."{{Ref/Reuse|hh3}}

For thousands of years, the ring and its control room were completely derelict. In [[2552]], after the [[United Nations Space Command|UNSC]] {{Class|Halcyon|cruiser}} {{UNSCShip|Pillar of Autumn}} crash-landed on the ring, [[Covenant]] scouts came across the control room, possibly through use of the [[Silent Cartographer]].  

When [[Master Chief Petty Officer|Master Chief]] [[John-117]] came across the control room, he integrated [[Cortana]] into the Core. Absorbing the wealth of knowledge, she informed him of a terrible secret and sent the Chief after [[Captain (Navy)|Captain]] [[Jacob Keyes|Keyes]] and his squad who were going after supposed a Covenant weapons cache, in reality a [[Flood containment facility]].{{Ref/Reuse|Halo: The Flood}}

Later, Halo's Monitor, 343 Guilty Spark, brought the Chief back to the control room in order to activate the ring. When he learned what the ring's true function was, the Chief yanked Cortana out of the panel and raced to stop the activation process.{{Ref/Reuse|Halo: The Flood V2}}

===Installation 08===

In the months after Installation 04's destruction, [[Installation 00]], the Ark, began constructing [[Installation 08|a replacement]] for the ring. During the [[raid on Installation 08]] in the immediate wake of the destruction of the [[Covenant]], [[John-117]], [[Arbiter]] [[Thel 'Vadam]], [[Avery Johnson|Sergeant Johnson]] and 343 Guilty Spark entered the control room of the replacement Installation 04, intending to activate the ring and sterilize the Flood outbreak at the Ark. Despite the [[Gravemind]]'s attempts to stop them from reaching the control center by deploying copious amounts of Flood forms in the area via [[Flood dispersal pod|dispersal pods]], the group eventually made it inside. However, 343 Guilty Spark, infuriated by Sergeant Johnson's attempt to fire the ring while still in an unfinished state, turned on the trio and killed Johnson. The Master Chief soon destroyed the monitor and inserted Cortana to the Core. She used the previous Installation 04's [[Activation Index]] to initiate the firing process of the unfinished Halo, which began to rapidly demolish the control room and prompted John-117 and the Arbiter to escape.{{Ref/Reuse|hh3}}
