NAC Connections and Releasing Circuits

Installation

3.8  NAC Connections and Releasing Circuits

The control panel provides four NAC terminals as shown in Figure 3.19. Each can be configured as 
Style Y (Class B) or Style Z (Class A) as shown in Figure 3.18. Each circuit can provide 1.5 A of 
current, but the total current drawn from the main power supply cannot exceed 7.4 A in alarm 
condition (refer to Table A.2). Additionally, TB10, TB2, and all 4 NACs share a maximum of 3.0 A 
in standby and 6.0 A in alarm; see Appendix A. NAC circuits are supervised and power-limited. 
Use UL-listed 24 VDC notification appliances only (refer to the 

Device Compatibility Document

).

NOTE: Any NAC can be programmed as a releasing circuit, and the releasing circuit must 
be supervised; see Figure 4.8–Figure 4.10. 

For more information, refer to Section 4 

“Applications” in this manual and the 

NFS2-640/E Programming Manual. 

Refer to the 

Device 

Compatibility Document

 for UL-listed compatible releasing devices. Sample connections for NAC 

terminals are shown in Figure 3.18. Follow sequence of steps in Section 3.2 “Installation 
Checklist”
Table 3.1; this is part of Step 6.
