Wiring IDNAC Class B Wiring
To connect the power supply to
appliances using Class B wiring:
1. Route the wire from the “+” and
the “-” outputs on the IDNAC
terminal block (TB2) to the
appropriate inputs on a
peripheral notification
appliance.
2. Route wire from the first appli-
ance to the next one. “T” tap-
ping is allowed. Repeat for each
appliance.
3. Repeat steps 1 and 2 for each
IDNAC output you want to use.

Notes: 1. Notification appliances are rated per individual nameplate label. Maintain correct polarity on termi-
nal connections.
2. Each IDNAC + and - terminal is rated for 2 identical wires. This allows up to 4 Class B T-TAP cir-
cuits directly from each IDNAC terminal block. See Figure 4-3.
