16 Input Drip Detector for the Trigger Racks ---------------------------------------------- Rev. 10-MAR-1995 The current idea is that the new Drip Detector Box will be mounted near the top of rack M110. In rack M110 there is about 5U of space above the Tier 2 Power Pan. The new Drip Detector Box is 2U tall. So we could keep 1U above the new Drip Detector Box and 2U between the Power Pan and the new Drip Detector Box. This location for the new Drip Detector Box allows the bulk of cables that connect the Drip Detector Box to the Drip Detector Strips in the row of 14 racks to run entirely inside this row of racks. 13 Drip Drip Detector Detector in Strip rack Strips +-------<-----------------<---------------<--- M114 in the row | of racks | | +----------------------+ M100-M101 ---+ +-->| | To the +------>| I O | Rack Voltage M101-M102 ---------->| N Drip U | +-------> Monitor in . | P Detector T | | M114 to . | U Box P |-->--+ Generate an . +------>| T U | | Alarm . | +--->| S T | | | | | | | M111-M112 ---+ | +----------------------+ | | | To the RPSS M112-M113 ------+ +-------> in rack M113 to trip power Cable length to connect the new Drip Detector Box to the Drip Detector Strips ----------------------------------------------------------------------------- Run Segment Lengths: From the rear of M110 to the front of M110: 2 feet From the top to bottom of M110: 7 feet In cable tray M111 to M114 16 feet Cables that go to Drip Strips: M100-M101 through M109-M110 will come down the right side of M110 as viewed from the back of M110 M110-M111, M111-M112, M112-M113 will cone down the left side of M110 as viewed from the back of M110 M114 will run from M110 over to M111 and exit through the top of M111 and then in the cable tray to M114 Slack Cable: Run that stay in the row of 14 racks will have an extra 2ft of cable. The run to M114 will have an extra 5ft of cable.
