2 Safety Warnings
This device is intended to be used as part of a safety system which may be used to protect personnel
and equipment from possible injury, damage, or loss.
As such it must be installed and wired according to these instructions and tested by suitably qualified
persons. No attempt may be made to tamper with the parts, open them, or use them outside of the
parameters contained herein.
The units are only designed to be fixed to surfaces using their inbuilt fixing holes. They must not
come into contact with each other or any other moving part when in use. The parts should never be
subject to impact or mechanical strain.
Safety switches should never be defeated or bypassed. It is imperative that all steps are taken to
ensure that any spare actuators are made unavailable, such that they cannot be used to defeat the
switch or reduce the protection offered by the system in any way.

3 Concept
The Miniature Warning Sign is intended to be
used in an indoor position to indicate messages
to personnel. Typically, the sign is fitted in a
room, adjacent to a door or on a piece of
equipment. The high-quality moulded case is
pleasing to the eye and the gloss finish makes
the unit easy to clean.
The sign offers a red danger and a green safe
indication and is powered by 24VDC or 48VDC.
LEDs are used to give a long service life.
Different red and green messages may be
displayed in the same area of the sign.
Messages may include text and/or symbols.
Standard and custom messages are available.
No message is visible when the sign is switched
off.
When fitted adjacent to a door, the sign is
intended to be located adjacent to the door
handle, approximately in line of sight as a
person reaches for the door handle to open the door.
The sign offers significant safety advantages over traditional warning signs which tend to be erected
over the top of the door, such as:
 Safer low voltage operation - no working on live equipment;
 Ground level access for installation and maintenance - no working at height;
 Fitted beside the door, not over it - no obstruction of the doorway during installation and
maintenance.
The Miniature Warning Sign can be directly operated by Lasermet’s interlock systems. A matching
access keypad is available.
Lasermet provides a full range of laser interlock equipment including control systems, interlock
switches, illuminated warning signs, laser shutters, door locks, external power supplies etc. which
can be connected to provide a complete laser interlock system. Full support, design and installation
is available from Lasermet, please contact us for any queries. Contact details are given at the end of
this manual.

4 Installation
The Miniature Warning Sign is designed to be permanently attached to a wall or other fixed vertical
surface. It is intended for indoor use and is not waterproof.
4.1 Positioning
The Miniature Warning Sign should be mounted in a convenient position for use and wiring.
Normally it is located on the outside (‘safe’) side of the entry door of the controlled area, on the wall
adjacent to the door handle, approximately 1.4m up from floor level.
During installation, wired connections will need to be made from the Miniature Warning Sign to the
Interlock Control System and allowance should be made for the installation of electrical conduit or
trunking if required to make entry to the unit.
Ideally the sign should be attached directly to the wall with the cables being fed from within the
wall. For hollow walls this should be straightforward. For solid walls it may be easiest and neatest to
feed the cables right through the wall from the other side.
Alternatively, the sign may be attached to a round BESA conduit box which may be buried or surface-
mounted, though this last option will result in the unit projecting further from the wall, making it
less stable and more vulnerable.
It is recommended that the centre of mounting is at least 100mm horizontally from the door
surround/architrave and at least 150mm from the edge of the door. There must be a flat
unobstructed area of wall extending at least 70mm above and 110mm below the mounting centre to
allow fitment and removal.
If a Lasermet ICS-KP12 or ICS-KP14 keypad is being fitted below the sign the centres should be at
least 140mm apart vertically.
Refer to Figure 1 for details of the fixing holes and cable entry. The backplate is secured using
preferably four screws on a 35.4mm square around the cable entry point. The backplate may be
used as a marking template. If using a BESA round conduit box, the holes will align with the cover
fixing holes.
Once all the holes have been made, secure the backplate as shown in Figure 1.
Feed the cables through the hole in the centre of the backplate.
NOTE: Make the electrical connections before attaching the unit to the backplate, see the Wiring
section.

5 Wiring
The standard sign is powered by 24VDC. A four-way terminal block is provided for the connections to
the red and green elements. The connections are shown in Figure 2.
Figure 2. Terminal Identification
The supply to the green safe element is connected with the positive to the GN+ terminal and
negative to the GN- terminal.
The supply to the red danger element is connected with the positive to the RD+ terminal and
negative to the RD- terminal.
Low voltage four-core flexible wire such as burglar alarm wire is ideal for connecting to the sign.
The sign typically draws less than 0.2A per colour. To protect the wiring and terminals the supply
should have an overcurrent protection device rated at 1A maximum.
Wiring diagrams are given below for connecting the sign to Lasermet’s ICS-6 Interlock Controller.
Connecting to a 48VDC Supply
When fitted with a voltage converter, the sign can accept a 48VDC supply voltage.
Use the voltage converter terminals (to the far left and/or far right of the board) to connect the
voltage supply. Do NOT directly connect the voltage supply to the connection terminals in Figure 2.
NOTE: Check the label indication at the back of the sign to determine if the sign can accept 48VDC.
