SPS NAC Field Wiring Guidelines, Continued

Class A (loop) NAC Wiring

Some or all of these output functions could be implemented using addressable devices or other relay modules instead, in which case the corresponding NAC output could be reassigned to other uses. The new configuration would require full testing of these functions to ensure compliance with AS 4428.1.

To connect the SPS to reverse-polarity, non-addressable notification appliances using Class A wiring, read the following instructions and refer to the figure below.

1.Route wire from the “B+”, “B-”, outputs on TB2 of the SPS to the appropriate inputs on a peripheral notification appliance. Use NAC1, NAC2, or NAC3 as required.

2.Route wire from the first appliance to the next one. Repeat for each appliance.

3.Route wire from the last appliance to the A+ and A- inputs on the same NAC circuit of TB1 of the SPS.

4.Repeat steps 1 through 3 for each NAC output you want to use.

5.Leave the 10 K, ½ W, brown/black/orange resistor (378-030) on each the “B+” to “B-” terminals of each unused NAC. No external end-of-line resistor is needed for circuits in use.

6.If the appliance/device to be used does not have an integral diode, a sufficiently rated blocking diode must be fitted between the incoming +ve wire and the +ve terminals of the device with cathode (stripe) to the device.
