Section 2: Overview; General Description; 1: Nca-2 Features - Honeywell NOTIFIER NCA-2 Instruction Manual

2.1 General Description

The NCA-2 Network Control Annunciator provides a text-based display and control device for a NOTI•FIRE•NET™ or High-Speed
NOTI•FIRE•NET™ system. The NCA-2 uses a 640-character LCD (16 x 40), a high-speed 32-bit microprocessor, flash memory and a
rubberized QWERTY keypad. It can display all events from a NOTI•FIRE•NET™ or High-Speed NOTI•FIRE•NET™ system and can
co-exist with other NCA-2s, DVC Series, DVC-RPU, DVC configured as a DVC-RPU, ONYXWorks, and NFS2-3030, NFS2-640, and
NFS-320 fire alarm control panels (FACPs).
NOTE: The NCA-2 is compatible with NOTI•FIRE•NET™ version 5.0 and higher, and with the High-Speed NOTI•FIRE•NET™.
Figure 2.4 gives simplified overview illustrations of typical applications for the NCA-2.
