General Description

The LEDArray Series Indoor displays are LED message centers designed
for light industrial, commercial and office use. They quickly display large
amounts of information in 8 colors and 3 rainbow effects (red only
versions are also available). These message centers are among the
brightest and sharpest indoor displays available.

Messages are entered through a wireless, remote control keyboard, as
easy to understand and use as an ordinary calculator. Exclusive 3-step
message entry with Automode programming eliminates the need to learn
complicated programming procedures. Within seconds, the user can
create exciting visual messages that cannot be ignored. 10 preset mass
notification messages are provided.

In applications requiring multiple units to communicate important informa­tion, Alpha displays can be networked and connected to a PC, to form a
powerful integrated visual information system throughout your plant or
business facility, or the LED Contact Interface Panel can be used for Fire
Alarm or Manual type activation.

DRY CONTACTS TO RS-485 DATA INTERFACE

Model: MNS-ctrl - for LEDArray and MegaDot signs

The ALPHA Discrete Input Interface allows messages to be displayed on standard LEDArray electronic signs
by using simple on/off contacts to trigger messages that have been stored in a sign. The ALPHA Discrete Input
Interface is designed for low-voltage applications.

Messages to be displayed are stored in a sign using either:

• Infrared handheld remote control

• Adaptive software such as ALPHA Messaging software

CPU / Input Module — serves as an interface between the Input Modules and LEDArray signs.
Up to four Input modules can be used, depending on the Operating Mode used. The eight, dry
contact inputs of each Input Module can be configured to one of five possible Operating Modes:

— Mode Ø: Discrete Fixed
— Mode 1: Momentary Triggered
— Mode 2: Binary Coded Decimal (BCD)
— Mode 3: Binary
— Mode 4: Counter

Power Module*not shown* — supplies power to the CPU Module / Input Modules

CONNECTIONS TO NETWORK ADAPTER

• Red (-) Differential: Connect to YL (Yellow Terminal)

• Black (+) Differential: Connect to BK (Black Terminal)

Drain Wire (Shield): Must be continuous throughout network.

•

NOTE: Only connect to RD (Red Terminal) if the sign
is a 4000, 7000 or 9000 series.

These modules are installed in a 12”x12”x4” deep box with a hinged door and cam lock to prevent unauth­orized access. The inputs to the modules are pre-wired to terminal blocks for easy installation. A pair of wires from
your dry contact(s) is all that is needed to activate the associated messages(s). The messages are pre-programed
but can easily be changed with a hand-held remote or laptop computer.

NOTE: Only one Operating Mode can be used at a time. For example, if three Input Modules were

connected together, all three modules would have to use the same Operating Mode.
