Mount single-space blank plate
onto compatible dress panel or
backbox trim ring
WARNING: Remove all power sources to equipment while connecting electrical components.
!
Leave the external, main power breaker OFF until installation of the entire system is complete.
WARNING: Several sources of power can be connected to the control panel. Before servicing the

3.5.6 Overview

Complete all mounting procedures and check all wiring before applying power. Electrical
connections include the following:
• Primary AC power source – 120 VAC, 50/60 Hz, 3.0 A (NFS-640E uses 240 VAC, 50/60
Hz, 1.5 A) from line voltage source. Overcurrent protection for this circuit must comply
with Article 760 of the National Electrical Code (NEC) and/or local codes. Use 12 AWG
(2.00 mm
• Secondary power source – 24 VDC from batteries, installed in the control panel (or in an
optional battery cabinet). Secondary (battery) power is required to support the system
during loss of primary power.
• External power sources – 24 VDC power for Smoke Detectors (4 wire), NACs, and
Annunciators.
See Appendix B "Electrical Specifications" for details and overall installation guidelines.
