Notification Systems.
NCA-2 Indicators and Controls
LED INDICATORS
• P OWER (green) illuminates when 24 VDC power is applied;
LED goes out if power is removed and NCA-2 is using a
battery.
• C ONTROLS A CTIVE (green) illuminates to indicate that the
NCA-2 control functions are active.
• F IRE A LARM (red) illuminates when at least one fire alarm
event exists; flashes when any of these events remain
unacknowledged.
• P RE -A LARM (red) illuminates when at least one pre-alarm
event exists; flashes when any of these events remain
unacknowledged.
• S ECURITY (blue) illuminates when at least one security
event exists; flashes when any of these events remain
unacknowledged.
• S UPERVISORY (yellow) illuminates when at least one
supervisory event exists (i.e., sprinkler valve off normal,
low pressure, fire pump running, guard’s tour, etc.);
flashes when any of these events remain unacknowl-
edged.
• S YSTEM T ROUBLE (yellow) illuminates when at least one
trouble event exists; flashes when any of these events
remain unacknowledged.
• O THER E VENT (yellow) illuminates for any category of
event not listed above; flashes when any of these events
remain unacknowledged.
• S IGNALS S ILENCED (yellow) illuminates if the NCA-2
Silence key has been pressed or if any other node sent a
Network Silence command; flashes if only some points on
a node are silenced.
• P OINT D ISABLED (yellow) illuminates when at least one dis-
able exists on the network or in the system.
• CPU F AILURE (yellow) activated by the watchdog timer
hardware, indicates an abnormal hardware or software
condition. Contact technical support.
FIXED FUNCTION KEYS
• Acknowledge
• Signal Silence
• System Reset
• Drill
• Fire Alarm Scroll/Display
• Security Scroll/Display
• Supervisory Scroll/Display
• Trouble Scroll/Display
• Other Event Scroll/Display
The five keys labeled S CROLL /D ISPLAY allow the user to scroll
through messages for the particular event type. For example,
pressing the F
IRE A LARM S CROLL /D ISPLAY key will scroll
through all fire alarm events, as details of each are shown in
the display area of the NCA-2.
NOTE: The O THER E VENT S CROLL /D ISPLAY key also scrolls
between Pre-Alarm and Disabled events.
• A CKNOWLEDGE – press this key to acknowledge off all
active events.
• S IGNAL S ILENCE – press this key to turn off all control mod-
ules, notification appliance circuits, and panel output cir-
cuits that have been programmed as Silenceable.
• S YSTEM R ESET – press this key to clear all latched alarms
and other events and turn off event LEDs.
• D RILL H OLD 2 S EC – press this key, holding it down for two
seconds, to activate all silenceable output circuits.
SPECIAL FUNCTION KEYS
• P RINT S CREEN – press this key to print what is currently on
the LCD screen.
• L AMP T EST – press this key to test the LED indicators on
the left of the keypad and to check firmware revision num-
bers.
• N EXT S ELECTION /P REVIOUS S ELECTION – these keys are
used when setting parameters in NCA-2 data fields; for
example, choosing a device type as a filter for requesting
a Node History.
• B ATTERY L EVEL – press this key to display voltage and
charging current level for system batteries. Displays levels
for local AMPS-24(E) or AMPS-24(E) connected to asso-
ciated NFS2-3030 or NFS-3030 node.
Specifications
Temperature and humidity ranges: This system meets NFPA
requirements for operation at 0°C to 49°C (32°F to 120°F);
and at a relative humidity (noncondensing) of 85% at 30°C
(86°F) per NFPA, and 93% ± 2% at 32°C ± 2°C (89.6°F ±
1.1°F) per ULC. However, the useful life of the system’s
standby batteries and the electronic components may be
adversely affected by extreme temperature ranges and
humidity. Therefore, it is recommended that this system and
all peripherals be installed in an environment with a nominal
room temperature of 15°C to 27°C (60°F to 80°F). Product
weight is 3 lbs (1.36 kilograms).
ELECTRICAL REQUIREMENTS
The NCA-2 may be powered from a Main Power Supply
AMPS-24(E) (see data sheet DN-6883) mounted in a seper-
ate cabinet (see specifications below); or from any UL Listed
non-resettable 24 VDC source from a NOTIFIER fire panel
(see panel data sheets). The battery on the NCA-2 mother-
board is for RTC and SRAM; holds the history memory
through power failure. Replacements are available (P/N
31004). Power source: 1) AMPS-24 (120 VAC, 50/60 Hz, 4.5
A maximum) or AMPS-24E (240 VAC, 50/60 Hz, 2.25 A max-
imum) power supply; 2) the NFS-640, NFS2-640 and NFS-
320 on-board power supply; or 3) a supervised +24 VDC
power supply that is UL/ULC-listed for fire protective ser-
vice. The current of the NCA-2 is 400 mA with backlight and
200 mA with the backlight off.
Product Line Information
