3.6 Connecting the Power Cables
3.6.1 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 (XLS140E 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 (3.31
mm
2
) wire (maximum) with a 600-volt rating.
• 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.
3.6.2 Connecting the Control Panel to AC Power
