TM 10-6665-297-13&P2-6DETECTORINSTALLATION (continued)2-6.4INSTALLINGWIRESFORALARMANDCONTROLDEVICES,ALLMODELS. Install, but do not connect wires for alarm and control devices as necessary in conduit.2-6.5 TESTINGFOROPENCIRCUITS,SHORTCIRCUITS,ANDLEAKAGEINDETECTORWIRES .Before connecting conduit wires to detector, to control module, or to alarm or process control equipment, use a high-voltage insulation and leakage tester (such as a “Megger”) to test wires for open circuits, short circuits, and for leakage to ground or to another wire. Megger readings for isolated circuits should exceed 100 megohms. Repair defects, if any, to assure proper operation of the detection system, and to prevent damage to components.NOTE:Warranty is void if abnormally high voltages or currents are applied to detector elements,control modules, or associated equipment.2-6.6 CONNECTINGCONDUITWIRESTOTHEDETECTOR .Using crimp-type connectors, solder lugs, or solder splices (in accordance with National Electrical Code specifications), connect conduit wires to the detector as follows:1.Connect active element wire A (green or red) of detector head to green conduit wire.2.Connect reference element wire R (black) of detector head to black conduit wire.3.Connect signal output wire C (white) of detector head to white conduit wire.Allconnectionsmustbecleanandtighttoassureoptimumperformanceofthemonitoringsystem.2-6.7 INSTALLINGDETECTORONCONDUIT .Attach detector to conduit by means of conduit union fitting.In hazardous locations, follow National Electrical Code, Article 501, for sealing conduit wiring in hazardous areas. For outdoor installations, use an explosion-proof drain fitting to allow removal of water that will accumulate in a conduit system, to prevent corrosion or partial shorting at splices.2-6.8CONNECTING CONDUIT WIRES FROM DETECTOR TO CONTROL MODULE ASSEMBLYTERMINALS:Install terminal lugs on conduit wires from detector and attach to control terminals withterminal screws as follows (Figures 2-11 through 2-15):23-96177/1/762-27
