Class A Wiring; Class B Wiring - Simplex 4007-9101 Installation Manual

6.6 Class A Wiring

To wire an IDNet section as a Class A circuit:
1. Make sure the jumpers on P2 are set to positions 3-5 and 4-6.
2. Route the wiring from the IDNet circuit primary terminals (B+, B-) on TB1 of the IDNet to the corresponding inputs on the first device.
3. Route the wiring from the first device to the next as in/out. See Figure 25: IDNet Class A wiring on page 32. Repeat this for each device.
4. Route the wiring from the last device to the terminals A+, A- to the panel, maintaining polarity.
5. Shielded wire is not recommended. If shielded wires are present, cut and tape off the shield at each end in the panel to prevent it from coming into
contact with other components. The metallic continuity of the shield must be maintained and insulated throughout the entire length of the cable.

6.7 Class B Wiring

When wiring the circuit as Class B, both the B+, B- and A+, A- terminals are available for parallel connections. Within the IDNet circuitry, A+ is connected
to B+, and A- is connected to B- so circuits can stem from either one. Additionally, two wires can be connected to each screw terminal.
To wire an IDNet as a Class B circuit, complete the following steps:
1. Set the jumpers on P2 to positions 1-3 and 2-4.
2. Route the wiring from the IDNet circuit primary terminals (B+, B-) to the corresponding inputs on the first device. It is possible to add up to 4
circuits on the terminal block when using Class B wiring. See Figure 26: IDNet Class B wiring on page 32 for the diagram.
3. Route the wiring from the first device to the next as in/out, see Figure 26: IDNet Class B wiring on page 32. Repeat this for each device.
4. Shielded wire is not recommended. If shielded wires are present, cut and tape off the shield at each end (in the panel and at the last device in each
run) in the panel to prevent it coming into contact with other components. The metallic continuity of the shield must be maintained and insulated
throughout the entire length of the cable.
