Section 2: System Overview
2.1 System Description
The NFS2-640/E control panel is a modular, intelligent fire alarm control panel (FACP) with an
extensive list of powerful features. The control panel uses the CPS-24/E integral power supply with
battery charger. This is combined with a mounting chassis and cabinet to create a complete fire
alarm control system. The panel supports FlashScan® protocol and has network capabilities. A
single SLC loop is supported with the basic equipment package; a second SLC loop can be added
by attaching an optional loop expander module (LEM-320).
Modular devices mount to the chassis to provide additional output circuits, including voice and
telephone modules to form a complete voice evacuation system. Five cabinet options are available
for enclosing system components; each is available in red or black.
The control panel has the capacity for installing up to 636 addressable points; 159 detectors and
159 monitor/control modules per SLC (Signaling Line Circuit).
