Connect a black wire between detector reference element lead (black, banded “R”) and controlmodule terminal marked DET 1, R.3. Connect a white wire between detector single output lead (white, banded “C”) and control moduleterminal marked DET 1, C.2-6.2.2 InstallingSecondDetectoronOneModule,ModelsCD802/832. Install a single detector as follows (Figures 2-8 through 2-11):1. Disconnect and remove 15-ohm paired resistor factory-installed on DET 2 terminals A, R, and C.2. Connect a green wire between detector green lead and control module terminal marked DET 2, A.3. Connect a black wire between detector black lead and control module terminal marked DET 2, R.4. Connect a white wire between detector white lead and control module terminal marked DET 2, C.2-6.3INSTALLING SECOND DETECTOR FOR CD800/830 SINGLE-CHANNEL MODULESIf two detectors are to be operated from a single CD800/830 control module, wires must be installed toconnect the leads of the second detector to an inter- mediate junction box or to the control moduleterminals marked DET 2, A, R, and C, as shown in Figure 2-18. (If a single detector only is to beconnected to a module, factory-installed, 15-ohm, paired resistors are connected across DET 2terminals A and C and C and R.) Maximum resistance allowable in A and R conduit wires is 2.5 ohmsper wire (or 5 ohms total A and R loop resistance, with A and R wire resistances the same within 1ohm). A 2.5-ohm maximum resistance is allowable where two detectors to a single module areinstalled. Wire gauge must therefore be determined with respect to length as follows:PowersupplywiresAandR:0-620 Feet:#16 AWG620-980 Feet:#14 AWGover 980 Feet:calculate fromTable 2-2 or Figure 2-17SignalreturnwireC:0-1100 Feet:#20 AWGover 1100 Feet:#18 AWG23-96177/26/852-26
