Installation NAC Circuit Wiring 2.3 NAC Circuit Wiring For wiring sizes, see Section 6.5, "NAC Circuit Loop Wiring Requirements". 2.3.1 Four NACs Configured for Class B (Style Y) Figure 2.10 shows four NACs configured for Class B (Style Y). • Trouble on NAC1 will illuminate LED1 SIG1 TRBL. • Trouble on NAC2 will illuminate LED2 SIG2 TRBL. • Trouble on NAC3 will illuminate LED3 SIG3 TRBL. • Trouble on NAC4 will illuminate LED4 SIG4 TRBL. HPFF12NACClassB.wmf Reference Resistor EOL same as Reference Resistor NAC 4 Horn Strobe Horn Strobe Horn Strobe NAC 1 NAC 2 NAC 3 Alarm Polarity Shown NACs 1 - 3 are wired the same as NAC4 and use ELR the same as Reference Resistor. Figure 2.10 Four NACs in Class B (Style Y) NOTE: 1. Typical ELR's for new installations can be 3.9k or 4.7k ohm. 2. The same gauge wire must be used if two conductors are connected to the same terminal of any terminal block. 3. Do not complete a continuous circuit around the screw terminal. There must be two separate wires on either side of the screw at the terminal block. "T-tapping" is absolutely NOT ALLOWED. 26 HPFF12 NAC Expander - P/N 53576:B 11/24/2010
