Class B NAC Wiring

To connect the SPS to appliances using Class B 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. “T” tapping is not allowed.

 

 

Repeat for each appliance.

 

3.

Route wire from the last appliance to the supplied EOLR or a 4081-9008 EOL

 

 

Harness (10 K Ohm, ½ W; brown/black/orange).

 

4.

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

 

5.

Leave the 378-030 EOL Resistor (10 K Ohm, ½ W; brown/black/orange) on

 

 

each unused circuit. The circuit must connect “B+” to “B-” terminals.

 

6.

If the appliance/device to be used does not have an integral diode, a blocking

 

 

diode must be fitted between the incoming +ve wire and the +ve terminals of the

 

 

device with cathode to the device.

The illustration below shows Class B wiring.

Important: Conductors must test free of all grounds.
