TM 10-6665-297-13&P 2-6 DETECTOR INSTALLATION  (continued) 2-6.8 Connecting Conduit Wires from Detector to Control Module Assembly Terminals   (continued) 1. Connect  red  or  green  conduit  wires  to  terminal  post  marked  DET  1,  A  on  terminal  panel  (Model CD80OP:  terminal TB-1, A-1). 2. Connect  black  conduit  wire  to  terminal  post  marked  DET  1,  R  on  terminal  panel  (Model  CD800P: terminal TB-1, R-l). 3. Connect  white  conduit  wire  to  terminal  post  marked  DET  1,  C  on  terminal  panel  (Model  CD800P: terminal TB-1, C-1). If two detectors are to be operated from a single control module, connect red or green, black, and white wires  from  the  second  detector  conduit  to  terminal  posts  DET  2,  A,  R,  and  C  respectively  (Model CD800P:  terminals TB-1, A-2, R-2 and C-2).  Remove factory-installed resistors from terminals DET 2, A and C, and C and R (CD800P:  TB-1, A-2 and C-2, and C-2 and R-2).  Figures 2-11 through 2-15 show connections, all models.) 2-6.9 TESTING OPERATING VOLTAGES AND COMPENSATING FOR CONDUIT WIRE VOLTAGE DROPS.  Special equipment required: 0-10 V range DC Voltmeter,    2% accuracy in 5-6 V range. Test Socket Adapter #0023-4027 (one furnished with each rack assembly) Circuit Card Extender #0023-4023 (except some CDSOOP models which have built-in extenders, and model  CD80OW,  for  which  the  card  extender  is  not  required.    Six-point  rack  assemblies  provide  an extender  in  storage  socket  at  inside  left  in  the  chassis.    Wall-mounting  four  and  eight-point  cabinets have extenders packed inside the cabinet.) Two people are required to test and adjust operating voltage:  one at the control module, and another at the detector.  This test must be conducted for each control/detector unit in turn.  Test detector operating voltage level and compensating for conduit wire voltage drops in accordance with the fol- lowing steps: 1. Make  certain  that  power  is  off  at  control  module  (PILOT  ON/OFF  light  unlit  on  control  module panel). WARNING:  Before opening detector housing, use a portable sniffer to determine that no hazardous gas is present in the vicinity. 2. Remove protecting covers from detector sensor element as follows: 23-9617 7/1/76 2-28
