2.6 CHECK AND TERMINATE ALL ZONES

NOTES:
A. Use the CARD SUMMARY BY LOCATION Report (Table 6) to determine the
location of the motherboard on which each specific circuit terminates.
• A stick-on "ADDRESS" label on each motherboard identifies that board's
number.
B. The above report is found within the computer printout portion of the Factory
Documentation.
C. Use the terminal identifiers to find specific terminals.
• See Figure 11(Custom Terminal Wiring Identifiers) for typical custom
terminal wiring identifiers.
D. Check each circuit for voltages, shorts or opens as follows:
1. With the meter set on 300VAC, read the voltage across the circuit.
• Meter must read 0 volts.
2. With the meter set on 60VDC, read the voltage across the circuit
again (this time in both directions).
• Meter must read 0 volts.
3. With the meter set on OHMS x 10 and its (+) and (–) leads connected to
the circuit's (+) and (–) wires respectively, check resistance.
• Readings must compare favourably with those shown in Table 1.
• If reading indicates an open in a circuit that includes a smoke detector,
make sure the detector head(s) are properly mounted and seated.
– Circuits always read "open" (infinity) if detector power is absent and
separately-powered devices (four-wire smoke detectors) are involved.
E. Connect the wires to their terminals.
