LCD-160

Liquid Crystal Display

General

The LCD-160 is a 640-character Liquid Crystal Display (LCD)
annunciator and remote control for the NOTIFIER NFS-3030/
NFS2-3030 Fire Alarm Control Panel (FACP). The LCD-160
will mimic the top portion (160 characters) of the NFS-3030/
NFS2-3030’s 640-character display. This provides the event
and preprogrammed custom messages as displayed on the
main panel. The full screen contains soft key functions, and
can display other panel information.

LCD-160 Features

• 640-character Liquid Crystal Display with backlit control.

• On-board input, output, and status indicators to support
diagnostics.

• Software upgrades and foreign-languages character sets
via serial port from a panel or other device using the
Remote Data Port (RDP) interface. Upgrades do not require
the replacement of any programmable devices.

• Rubberized keypad.

• Input for AKS-1B key switch.

• Fits in two ACS annunciator module locations.

• Display and Control Center (DCC) participation/indication.

RDP Interface

Any communication between the control panel and any RDP
device, such as the LCD-160, occurs over an RDP interface.

• RDP interface communication is supervised by the FACP
and the LCD-160.

• RDP bus can drive up to 32 RDP devices. The FACP must
be at one end of the bus; the last RDP device on the circuit
must have an enabled end-of-line resistor.

• Each LCD-160 on the bus requires a non-resettable 24
VDC power connection. The power circuit is inherently
supervised and a loss of power registers as a communica­tion failure at the control panel.

• The LCD-160 can be powered by a regulated remote power
supply listed for fire-protective signaling use. If the 24 VDC
power comes from a non-power-limited source, it must
remain separate from the power-limited RDP bus.

Specifications

Input supply voltage (TB2): Regulated, filtered 24 VDC via
non-resettable power supply interface listed for fire-protective
signaling use. Sources can be: panels with integrated power
supplies, main power supplies (AMPS-24, etc.), auxiliary
power supplies (APS2-6R, etc.); or a compatible accessories
output. If RDP devices are to be powered by separate power
supplies, a common reference connection must be estab­lished.

Data communications port (TB1): Power-limited RDP inter­face.

Annunciator Control Systems

Current draw: Standby current: 0.300 A with backlight on,

0.075 A with backlight off. Alarm current: 0.325 A with back­light on, all LEDs active.

RDP BUS WIRING SPECIFICATIONS

Wiring distance: 4000 feet (1219.2 m) at 18 AWG (0.78 mm²)
between the panel and the last device on the RDP bus (sub­ject to system’s power restrictions).

Wiring size: 18 to 12 AWG (0.78 to 3.1 mm²) twisted-pair
cable, with characteristic impedance of 120 ohms ± 20%.

Wire resistance: Limit total wire resistance to 100 ohms on
the RDP bus, and 10 ohms on the RDP device power circuit.
Unloaded resistance between RDP connectors must be
greater than 1K ohm. A remote power supply is required if total
power wiring resistance exceeds 10 ohms.

NOTE: 1) DO NOT RUN CABLE adjacent to, or in the same con­duit as: 120 VAC service; “noisy” electrical circuits that are power­ing mechanical bells or horns; audio circuits above 25 Vrms; motor
control circuits; SCR power circuits; or non-power-limited circuits.

2) Refer to LCD-160 Manual, document no. 51850, if RDP devices
are to be mounted in SEPARATE CABINETS or powered by

REMOTE POWER SUPPLIES.

PHYSICAL SPECIFICATIONS

Temperature/humidity range: This system meets NFPA
requirements for operation at 0 – 49°C/32 – 120°F and at a
relative humidity 93% ± 2% RH (noncondensing) at 32°C ±
2°C (90°F ± 3°F). 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 its
peripherals be installed in an environment with a normal room
temperature of 15 – 27°C/60 – 80°F.

Shipping weight: 2.50 lb. (1.134 kg)

LCD-160

The liquid crystal display is 40 characters wide and 16 lines
deep, and displays all programming screens and other infor­mation. The keypad is functional only when an entry is
requested by the system. Enter or change fields and issue
commands on the display by using the two types of keys on
the keypad: fixed function and soft keys.

Fixed function keys are the ten keys labeled on the front of
the LCD-160, operating at all times on all screens unless oth­erwise noted. With both an active command center and DCC
enabled at the panel, Acknowledge, Signal Silence, System
Reset, and Drill require permission before they can be pro­cessed.

Acknowledge: Press to respond to any event or trouble sig­nal. If enabled, silences the LCD-160 piezo sounder. Sends an
acknowledge message to the panel.

Signal Silence: Press to send a system silence command to
the panel, with the particular silencing action information
stored at the FACP. Verification screen appears on networked
displays.

System Reset: Press to send a system reset command to the
panel, with the particular reset action information stored at the
FACP. Verification screen appears on networked displays.

Drill: Press (hold for two seconds) to activate all silenceable
fire output circuits.

Lamp Test: Press to test the LED indicators and the piezo, or
display firmware version numbers.

Fire Alarm: Scroll/display a list of associated events.

Security: Scroll/display a list of associated events.

Supervisory: Scroll/display a list of associated events.

Trouble: Scroll/display a list of associated events.

Other Event: Scroll between prealarm and disabled events.

For complete information on key functions and effects on dif­ferent panels, refer to the LCD-160 Manual and panel manu­als.

Soft keys are the six keys to the right and left of the display.
Use them to select commands that appear on the display for
each different screen. Refer to the screens in the LCD-160

Manual for descriptions of the applicable soft keys.

STATUS LED INDICATORS

Power (green) illuminates when AC power is within normal
operating limits.

Fire Alarm (red) illuminates when at least one fire alarm event
exists. It will flash if any of these events are unacknowledged.

Pre-Alarm (red) illuminates when at least one pre-alarm event
exists. It will flash if any of these events are unacknowledged.

Security (blue) illuminates when at least one security event
exists. It will flash if any of these events are unacknowledged.

Supervisory (yellow) illuminates when at least one supervi-
sory event exists. It will flash if any of these events are unac­knowledged.

ble event exists. It will flash if any of these events are unac­knowledged.
