NCA-2 Keypad Layout Overview
2.5 NCA-2 Keypad Layout
The keyboard figure below illustrates the basic layout. The keypad is described in detail in the operation section of this manual, in “The
Keypad” on page 36.

2.6 NCA-2 Components
2.6.1 NCA-2 Basic Components
The NCA-2 assembly includes the following components: NCA-2 motherboard, QWERTY keypad with LCD display, and NUP commu-
nications cables (#75577) used when connecting the NCA-2 to other NUP-compatible devices.
2.6.2 EIA-232 Optional Devices
The NCA-2 supports the following optional printer and display devices: PRN series printers and Keltron printer connecting to the NCA-
2 via EIA-232 interfaces.
PRN Series Printer. This is an 80-column, 9” x 11” tractor-feed printer that can be located up to 50 feet (15.24 m) from the Fire Alarm
Control Panel (FACP). The PRN series prints a record of all system events and status changes within the network monitoring system. It
also time-stamps the printout with the current date and time.
Keltron Printer. The VS4095 is a two-color (red/black), 40-column, 24 VDC printer that mounts in a separate cabinet next to the
FACP. The VS4095 meets UL fire and security requirements for an ancillary device.
2.6.3 EIA-485 Annunciator Devices
The NCA-2 can be used to monitor annunciator devices and Annunciator Control System (ACS) modules. ACS modules connect to the
NCA-2 using an EIA-485 ACS Mode connection. The NCA-2 can support up to 32 annunciator devices. ACS devices use LED arrays to
show the status of points or zones within the network monitoring system. Annunciator points are programmable from the NCA-2 inter-
face. The following annunciator modules (and their corresponding expander modules) are supported by the NCA-2:
ACM-8R. The Annunciator Control Module-8R provides the control panel with a mappable relay control module. Relays can be
selected for mapping anywhere in the system memory (in groups of eight). The ACM-8R provides eight Form-C relays with 5A @125
VAC (resistive) or 5A @30 VDC (resistive) or 2A @125 VAC (inductive) contacts. It tracks any group of eight zones within the system.
ACM-16AT and AEM-16AT. The Annunciator Control Module-16AT has 16 red alarm and 16 yellow trouble LEDs. The Annunciator
Expander Module-16AT expands the ACM-16AT by 16 annunciator points. Up to three of these expander modules can be supported by
an ACM-16AT, for a maximum of 64 annunciator points.
ACM-24AT and AEM-24AT. The Annunciator Control Module-24AT has 24 color programmable on/alarm LEDs (set to red, green, or
yellow) and 24 yellow trouble LEDs. An ACM-24AT can support up to three Annunciator Expander Modules (AEM-24AT) for a maxi-
mum of 96 points.
ACM-32A and AEM-32A. The Annunciator Control Module-32AT has 32 red alarm LEDs and a system trouble LED. The Annuncia-
tor Expander Module-32A expands the ACM-32A by 32 annunciator points, for a maximum of 64 points.
ACM-48A and AEM-48A. The Annunciator Control Module-48A has 48 color programmable on/alarm LEDs (set to red, green, or
yellow). The corresponding expander module expands the ACM-48A by 48 points for a maximum of 96 points.
