Air conditioning in the hall consists of heating and cooling provided by the HVAC unit mounted on the ceiling of the hall.
Each Detector Shielding House has two heat pumps for heating and cooling. So far we only use them for cooling. Go figure.
The HVAC unit for the counting room is the unit directly in front of the counting room. Air is forced under the raised floor and the return is above the drop ceiling. Thermostat controls for the counting rooms are on the wall in the center section, next to the interior door.
The Gas Shed has a heat pump with suplemental resistive heating.
Cable routing in the Counting Room is done in cable tray under the raised floor. There is cable tray above the Control Console. Route cable in this tray.
Cable from the Counting Room to Hall A is run down an access shaft. The shaft is located in a small room toward the rear of Counting Room A. Three sets of cable tray are mounted in this shaft. Each tray breaks out into Hall A in a slightly different manner. Before running cable, check which tray will be most optimal in Hall A.
Hall A has two main access routes. The main access is via the truck ramp which enters on a side of the hall. The truck ramp is just to the right as you enter the parking lot to the Counting House.
There is a personnel access near the beam entrance to the hall. Cables to the counting room are routed in cable trays along one side. From this accessway to the counting rooms there are both an elevator and a stairway. The stairway has 47 steps from top to bottom.
The detector shielding houses have an Inergen fire suppression system. When trigged the system releases a sufficient amount of inert gas into the hut to drive the oxygen level too low to sustain combustion. That's the theory, anyway.
