Wiring Class A Wiring
Note: The Class A wiring style is set up in the programmer. Refer to the 4007ES Programmer’s manual,
579-1167, for more information.
To connect the power
supply to reverse-polarity,
non-addressable
notification appliances
using Class A wiring:
1. Route wire from the
“B+” and “B-” outputs of
the power supply to the
appropriate inputs on a
peripheral notification
appliance. Use NAC1,
NAC2, NAC3 or NAC4
(2.).
2. Route wire from the first
appliance to the next
one. Repeat for each
appliance.
Figure 3-3. Class A NAC Wiring
3. Route wire from the last appliance to the A+ and A- inputs on the same NAC circuit of the
power supply.
4. Repeat steps 1 through 3 for each NAC output you want to use.
5. Leave the 10 KOhms, ½ W, brown/black/orange resistor (378-030) on each unused circuit.
No external end-of-line resistor is needed for circuits in use.
Class B Wiring
Note: The Class B wiring style is set up in the programmer. Refer to the 4007ES Programmer’s
manual, 579-1167, for more information.
To connect the power
supply to appliances using
Class B wiring:
1. Route wire from the B+,
B- outputs on TB2 and
TB3 of the power sup-
ply to the appropriate
inputs on a peripheral
notification appliance.
Use NAC1, NAC2,
NAC3, or NAC4.
2. Route wire from the first
appliance to the next
one. “T” tapping is not
allowed. Repeat for
each appliance.
Figure 3-4 Class B NAC Wiring
3. Route wire from the last appliance to the EOLR harness (10KOhms, 1/2 W: P/N 733-894).
4. Repeat steps 1 through 3 for each NAC output you want to use.
5. Leave the factory installed EOL Resistor (10 KOhms*, ½ W; brown/black/orange) on each
unused circuit. The circuit must connect “B+” to “B-” terminals.
6. Document EOL value in panel per circuit.
*If using a 4007ES hybrid panel, keep the original value and set the programmer accordingly.
