Safety & Installation
WEEE Directive
The Waste Electrical and Electronic Equipment (WEEE)
Directive was agreed on 13 February 2003, along with the
related Directive 2002/95/EC on Restrictions of the use of
certain Hazardous Substances in electrical and electronic
equipment (RoHS). The Waste Electrical and Electronic Equipment Directive
(WEEE) aims to minimise the impacts of electrical and electronic equipment
on the environment during their life times and when they become waste.
All products manufactured by Sonifex Ltd have the WEEE directive label
placed on the case. Sonifex Ltd will be happy to give you information about
local organisations that can reprocess the product when it reaches its “end
of use”, or alternatively all products that have reached “end of use” can be
returned to Sonifex and will be reprocessed correctly free of charge.
RoHS Directive
The RoHS directive limits the use of certain hazardous
substances currently used in EEE manufacture, including
lead, mercury, cadmium, hexavalent chromium, and
halide-containing compounds PBB (polybrominated biphenyl) and PBDE
(polybrominated diphenyl ether). Elimination of these substances will result
in more environmentally friendly recycling of electronic equipment.
Sonifex Ltd practices lead-free (LF) manufacturing processes and does not
use any of the hazardous substances identified in the European Union’s
Restriction of Hazardous Substances (RoHS) directive. The manufacturing
processes include the assembly of purchased components from various
sources. Product is offered as RoHS compliant, or LF, only after sufficient
evidence is received from the component manufacturers that their
components are RoHS compliant. Sonifex Ltd relies solely on the distributor,
or manufacturer, of the components for identification of RoHS compliance.
Thus whilst every effort is made to ensure compliance, Sonifex Ltd makes
no warranty, or certification, or declaration of compliance concerning said
components.
Atmosphere
The units should be installed in an area that is not subject to excessive
temperature variation (<0°C, >50°C), moisture, dust or vibration.
Handling Notes
The SignalLED sign should be installed in an area which is not subject to
excessive heat or cold. Also, you should avoid installing it in atmospheric
conditions which are dusty, smoky, or dirty, or where there is moisture or
vibration. The sign is for internal use only. The unit is not sealed and cannot
be used outside or in very damp or humid environments.
Do not use any solvents to clean the sign. Use a soft dry brush or a clean
cloth moistened with water or mild detergent.
Avoid using the SignalLED sign close to strong sources of electromagnetic
radiation such as video monitors or high power electric cabling.
In all cases the SignalLED sign should be installed and serviced by qualified
personnel.

Introduction & Installation 1
Introduction
The SignalLED sign is a new elegant approach to illuminated displays and
signage. Using the latest technology and components, the SignalLED sign
can be simply configured onsite for colour, brightness and mode using the
LD-RPC remote control.
• Choose from white, orange, brick red, cyan, red, magenta, blue,
yellow or green.
• Choose from a large range of different sign text.
• Illumination modes: constant, flashing, pulsing, fading and off.
• Two control pull-low inputs.
• Single or twin signs with separate controls.
• DC input power supply provided.
• Flush mounted to the wall or end mounted.
• Simple to install.
• Custom signs can be made to order.
Mounting The Sign
Route the signal and power supply cables before finalising the mounting
of the sign. These cables can be routed either through the aperture, or
through the cable cut-outs in the back of the wall mount moulding.
The LED sign should be mounted on a firm solid surface. The sign is supplied
with a mounting kit comprising 2 x wall plugs and 2 x large flange screws.
Note: You’ll need the following tools to mount the sign: an electric drill
fitted with a 6mm diameter masonry drill bit, a No.1 Pozi-drive screwdriver
and a spirit level.
- Drill 2 holes, approximately 34mm deep, using a 6mm diameter
masonry drill at the pitch shown on the drawings.
- Insert the wall plugs flush with the surface.
- Use a spirit level on the aluminium tube section to set the sign level
before fully tightening.
The screws can also be used for fixing into wood. For correct fitting drill a
small pilot hole into the wood before fitting the screw.
Opening The End Covers
To get access to the sign mounting points, the side covers need to be
opened. Use a No.1 Pozi-drive screwdriver to unscrew the side cover and
gently slide the cover forward approximately 8mm until it reaches the
stops. Pivot open the cover. Please note: do not to use excessive force
when opening the cover.

LD-20F1 & LD-40F1 Flush Sign Mounting
Requirements
This sign is to be mounted flush to a wall. Minimum clearances from the
sign to an adjacent wall or ceiling are shown below.
Fig 2-1: LD-20F1 & LD-40F1 Flush Sign Mounting Requirements
An absolute minimum of 60mm is required for the opened end cap, a
right angled screwdriver would be needed to screw (unscrew) the end cap
retaining screw.
End Mounting Requirements
To create an attractive invisible-fixing finish, the SignalLED assembly is
clipped into a wall mount plate. The wall mount plate must be securely
fitted to a smooth, solid surface before attempting to fit the SignalLED
assembly. Drill 2 holes, approximately 34mm deep, using a 6mm
diameter masonry drill, and attach the wall mount plate (coloured red
in the illustration above) to the wall. At this point, the LD-IT, end-mount
installation tool can be used to hold the sign in place while you connect
the power and signal cables. The cable retention clips can be used to hold
the cables in the sign. See information on connecting the Power and Signal
cables.
The sign is fitted by locating the four internal hanger plate hooks into the
four slots in the wall mount plate. Once located, hold the sign around the
end moulding of the SignalLED assembly (where the door is fitted) and
press down into its final position.
The sign retaining pins will clip into the indentations on the side of the wall
mount plate and this should result in a click as the plastic pins move into
their final position.
Note: a reasonable amount of force is needed to fully connect the LED sign
assembly to the wall plate.

LD-KC1 Ceiling Mounting Kit
Open the end covers of the sign. Take the 5mm screw out of each of the
LD-KC1 brackets and use the screws to attach the sign covers to them,
where indicated on the drawing below. Ensure that the sign cover
sits comfortably against the metal plates on each of the bracket.
The LD-KC1 ceiling mounting kit can be used for mounting a 40cm or
20cm flush mounting sign either down from the ceiling
or up from a surface, e.g. table-top
or top of a rack.
Connecting The Power and Signal Connections For Flush
Mounted Signs
To get access to the cable connection block and the mode switches which
are on the PCB inside the sign, the door on the underside of the end
plastic moulding must be opened.
To open the door push the clip towards the sign and pull down on the
small lip, see Fig 2-5. Do not attempt to remove the door from the end
moulding. Access to the connection block and the mode switches is
possible with the door fully open.

Fig 2-8: Opening The Access Door
Power Supply
The sign can be connected and powered either with the supplied DC
power supply, or with a regulated DC supply rated 5V to 7V DC, 0.5A
minimum. Please note that the current that a power supply can supply,
will be affected by the type of wiring used and its length, i.e. it’s total
impedance. For example, using bell-wire presents too high an impedance
and should not be used. See the website FAQs for more details. Please
check the supplied DC power supply to confirm which lead is +6V and
which is 0V.

Pin 2 (+6V) @ 500mA
Pin 3 (0V)
Pin 4 (Signalling Input 2)
Fig 2-9: Wire link To Illuminate Sign When Powered
Please note it is essential that the ground pin (0V pin 3) is connected
properly before powering up the sign, or firmware corruption may occur.
The signalling inputs are used to control the sign and are pulled low
(to 0V, pin 3) to activate. On signs manufactured before 14/10/2011
if driving more than one LED sign from the signalling inputs, or power
supply, then the LED sign pins should be diode protected to prevent a
reverse current condition.

Installation 2
Please note pins 3 (0V) and 1 (input 1) are linked by default so that the sign
will illuminate in its default mode when first powered up.
Use a small flat blade screwdriver to undo the connection block screw
terminals. Do not fully remove the screws from the terminals - they only
need 2 or 3 full turns to accept the wire ends.
Step 1: Connect the power supply 0V lead to Pin 3 (Ground/0V), along with
the link, on the connector block.
Step 2: Connect the power supply +6V lead (normally marked by a white
stripe, or white text on the wire - test this with a voltmeter if you are
unsure) into pin 2 on the connector block. Configured like this, the sign will
illuminate when powered.
Step 3: If using Signalling input 1 to control the sign, remove the link
completely and connect a switch or other contact closure between Pins 1 &
3 (0V) of the connector block. If using Signalling input 2 to control the sign,
remove the link completely and connect a switch or other contact closure
between Pins 4 & 3 (0V) of the connector block.
When the power and signalling connections have been made, close the
access door by pressing the clip back to its original position. It will click into
place when it is fully home.
After all of the terminations have been checked and the cables have been
routed through the cable clamps, close the end cover by reversing the
opening procedure, taking care not to overtighten the retaining screw.
7V-36V Extended DC Voltage Option
The LD-DC option, or LDD version, of a sign allows a SignalLED main circuit
board to accept a DC input in the range 7V-36V, for example, if you have a
12V or 24V distributed DC power network.
It has the same signal and power pins as the standard sign where Pin 3 = 0V
and Pin 2 = +Volts.
Where a longer cable run is required or the cable itself has a relatively
high resistance, (CAT5 network cable for example), the DC/DC PCB may
be preferable. In such cases the higher voltage will reduce the amount of
current required by the sign. For example, the LED sign draws 500mA at 6V,
giving a total power of VA = 6 x 0.5 (3VA). Therefore, for 24V, the current
required would be 3VA /24V = 0.125Amps.

3 Programming
6
Programming Colour &
Illumination Modes
SignalLED signs bought after 1st December
2010 are programmed using a separate
handheld remote control, instead of being
programmed using DIPSwitches on the sign.
Please note that the remote control must
be ordered separately, LD-RPC. Please
contact your Sonifex distributor for ordering
information.
Although the SignalLED is delivered as standard to indicate a certain colour
when a pull-low (to 0V) input signal is applied, the sign is programmable
to allow a number of different display modes and uses. For example, the
sign can be made to switch between 4 colours, one for each of the input
conditions below. The sign can also illuminate a certain colour when no
input signal is connected, i.e. it can be permanently illuminating, or it can
be made to switch from one colour to another on application of an input
signal.
Setting The Colour & Display Mode(s) of The Sign
The sign can be set to illuminate in 4 different states according to the
combination of the 2 x pull-low signalling inputs present at the input
connector block:
• Connect pin 1 to 0V to select input 1.
• Connect pin 4 to 0V to select input 2.
For each of the 4 states, the following features can be adjusted and set:
• Divide Point – This allows you divide the sign into two separate sections,
to set the size of each section and to set the size of a ‘dead area’ in
between the two sections, if required.
• Colour of each section.
• Brightness of overall sign illumination.
• Mode of sign operation, selectable from on, off, flash, pulse and fade.
Enter Programming Mode
To enter programming mode, open the Access Door (See Fig 2-5) which
exposes the infra-red receiver. Then point the remote control unit at the
opening and press & hold the PROGRAM (7) button for 3 seconds until the
LEDs in the main sign quickly cascade away & to the opening. This indicates
that the unit is in the Programming Mode.
To exit the Programming Mode, press & hold the PROGRAM (7) button
until the LEDs cascade away & to the receiver again.
During programming the input state being programmed is reflected in the 2
LEDs positioned in the opening:

Programming 3
Once in programming mode the sign will default to input state 1, press the
INPUT (8) button to step through the input states 2 – 4 *, until you have
selected the one you wish to change.
(* noting that the green LED indicates Input 1 and
the red LED
input 2.)
Setting The LED Sections of The Sign
The sign can be treated as a single sign or can be
split into two separate sets of LEDs anywhere along
the sign’s length, referred to as Sections 1 and 2
below, with a non-displaying centre section, the
‘dead zone’.
Press the DIVIDE (6) button to set the divide position for Section 1. Pressing
the DIVIDE (6) button again alternates the currently selected section
between Sections 1 and 2.
Section 1 initially consists of the 9 LEDS closest to the opening, with Section
2 being the 9 LEDs furthest away (on a 40cm sign).
Pressing the + (2) button advances the Section 1 divide position one LED for
each time you press the button. If Section 1 reaches Section 2 then Section
2 is pushed back (i.e. its divide position retreats).
Pressing the – (1) button causes the Section 1 divide point to retreat. But
this time Section 2’s divide position remains unchanged and a dead zone
(i.e. no LEDS illuminate here) is created. Similarly when Section 2 is being
set the – (1) button will advance Section 2 into Section 1 causing the
Section 1 divide position to retreat, but pressing the + (2) button will cause
the divide position of Section 1 to remain unchanged again introducing a
dead zone. This is complex to explain and it’s probably better that you try it
yourself to see how it works!
The divide point for Section 1 or Section 2 cannot be moved so that the
Section 1 is not visible. To set the sign to all one colour we suggest moving
the divide point of Section 1 to its maximum which will make Section 2
invisible, although the same result can be achieved by setting both sections
to the same colour.
Setting The Colour of The Section/Sign
To set the colour of each Section, (or the whole sign if only one Section
is defined), press the COLOUR (5) button to select Section 1. Pressing the
colour button again alternates the currently selected section.
Press the + (2) and – (1) buttons to change the selected colour according to
the colour table below. Normally the User colour setting is undefined and
therefore not selectable. However, for special orders Sonifex can create
distinct colour sets and these will use the User colour setting.

If The Sign Appears To Be Off
When starting to program the sign it may be unclear what the initial state
of the sign is. For instance if the sign is off, it’s hard to know whether the
Section 1 colour is set to off, whether the Section 2 colour is set to off,
whether an entire ‘dead zone’ has been configured, or whether there is a
mix of all 3 of these states. To make sure that the display state is known,
perform the following actions:

Programming 3
1. Go into Programming Mode by pressing and holding the PROGRAM
(7) button.
2. Press the INPUT (8) button to select the required input.
3. Press the DIVIDE (6) button to enter divide programming. Press the +
(2) button three times to ensure that Section 1 is visible.
4. Press the DIVIDE (6) button again and press the – (1) button to ensure
that section 2 is visible
5. Press the DIVIDE (6) button again and press the – (1) button to ensure
that the dead zone is visible.
If the display is still off then:
1. Press the COLOUR (5) button again and press the + (2) button to
ensure that Section 1 is assigned a colour.
2. Press the COLOUR (5) button again and press the + (2) button enough
times to ensure that Section 2 is assigned a different colour to that
assigned to Section 1.
This should confirm that a colour can be programmed.
Resetting The Sign to Factory Defaults
The sign can be set back to the factory default colours and illumination
mode as follows: Enter the Programming Mode and press and hold the
MODE (3) button for 10 seconds. The sign will now show the original
colour(s) and mode(s).
