36 NCA-2 Manual — P/N 52482:M5 03/20/2019
Section 4: Operation
This chapter covers basic operation of the NCA-2 and control features available to the operator using the NCA-2’s keypad and 640-char-
acter LCD display.
4.1 The Keypad
The keypad includes the Status LED indicators, soft keys, alphanumeric keys, fixed and special function keys. The alphanumeric portion
of the keypad is in standard QWERTY format. This keypad is functional mainly when an entry is requested by the system. Otherwise,
pressing the keys results in no entry.
Figure 4.1 The QWERTY Keyboard Interface
4.1.1 Fixed Function Keys
The nine keys aligned along the upper right edge of the keypad/display are fixed function keys.
ACKNOWLEDGE - Press this key to acknowledge an off-normal event displayed on the screen. Use to respond to a new alarm or
event.
SIGNAL SILENCE - Press this key to turn off all control modules that have been programmed as silenceable. (all nodes mapped to
NCA-2).
SYSTEM RESET - Press this key to clear all latched alarms and other events as well as turn off event LEDs. If alarms or other off-nor-
mal events exist after reset, they will resound the system and relight the LEDs. Unacknowledged events will not prevent reset from func-
tioning.
The System Reset key will not immediately silence active outputs. If the Control-by-event programming conditions for the output are not
met after reset, the output will deactivate. (Typically 30 seconds local, 60 seconds network.)
If Fire and MNS alarms exist on the network at the same time, a second System Reset needs to be performed to fully reset the network.
The NCA-2 will display
MN SYSTEM RESET or FIRE SYSTEM RESET, depending on which event type has priority.
DRILL (ALARM SIGNAL for Canadian applications)
HOLD 2 SEC. - Press this key, holding it down for 2 seconds, to activate all
silenceable fire output circuits (all nodes mapped to NCA-2).
LAMP TEST - Press this key to test the LED indicators on the left of the keypad and the piezo. Pressing the key longer than 5 seconds
will display firmware version numbers on the display screen.
BATTERY LEVELS - Press this key to display battery voltage.

NOTE: Key functions are as described below unless the Display and Control Center (DCC) option is enabled and the DCC is at another
location. When this panel is not the DCC on a network, permission must be granted from the DCC before Signal Silence, System Reset,

send a permission request to the DCC.
