Notifier CPU2-640E Central Processing Unit with Integral Power Supply, 240 VAC

Notifier CPU2-640E — central processing unit and integral power supply for the NFS2-640E intelligent addressable fire alarm control panel.

The E suffix marks the 240 VAC mains version; the otherwise identical CPU2-640 is the 120 VAC board. It ships factory-mounted on its chassis and carries the FlashScan polling, the built-in notification circuits and the battery charger for a complete ONYX Series NFS2-640E system.

• Primary input 220/240 VAC, 50/60 Hz, 2.5 A
• Offline switching supply rated 3.0 A, 6.0 A in alarm, shared by all internal circuits
• One isolated intelligent signaling line circuit expandable to two, Class A, B or X
• 159 intelligent detectors plus 159 monitor or control modules per loop
• Four notification circuits at 1.5 A each; resettable 24 V at 1.25 A
• Battery charger range 18 to 200 AH at a 27.6 V float rate
• UL and ULC Certified S635 and FM Approved; shipping weight 14.55 lb

Confirm the mains voltage before ordering, because the CPU2-640 is the same board built for 120 VAC. CPU2-640E-PO and CPU2-640E-SP are the Portuguese and Spanish versions of this part.
