Class B Supervised Wiring
Figure 4-5 shows how to wire for Class B input and output supervision. Use in/out wiring methods for proper
supervision (Refer to the Appendix for notification appliances approved for use with the HPF902ULADA.)
Class B Output Notification Circuits
Figure 4-5 shows four, 1.5 A devices wired as Class B.
Place a 4.7k ohm EOL resistor (provided) at the end of each circuit to enable supervision when using all outputs
as Class B notification appliance circuits. The 4.7k EOLs must be wired to the terminals whether or not you are
using all output terminals.
