SPS NAC Field Wiring Guidelines, Continued

Class A NAC Wiring

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 (between 0.75 mm2 and 4 mm2) 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 configured..

 

 

 

 

 

 

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 to the device.
