DETECTOR INSTALLATION (continued)
Connecting Conduit Wires from Detector to Control Module Assembly Terminals (continued)
Connect red or green conduit wires to terminal post marked DET 1, A on terminal panel (Model
CD80OP: terminal TB-1, A-1).
Connect black conduit wire to terminal post marked DET 1, R on terminal panel (Model CD800P:
terminal TB-1, R-l).
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.)
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:
Make certain that power is off at control module (PILOT ON/OFF light unlit on control module
WARNING: Before opening detector housing, use a portable sniffer to determine that no hazardous
gas is present in the vicinity.
