Concept
Lasermet Ultra LED Signs are intended to be wall mounted for which purpose several mounting
options exist. The sign is for indoor use only and should not be used in damp areas or places of high
humidity.
The sign is designed to give a long service life and has no user-replaceable parts inside.
The sign must be powered by a smoothed and regulated 24VDC supply capable of providing at least
0.7A. In order to minimise the effects of voltage loss in the wires the power supply should not be too
far from the sign and adequate wire thickness must be used in order that the voltage at the sign is
within the specified limits at the input to the sign when it is illuminated.
The 24V operating voltage provides enhanced safety within the sign and supply wiring compared to
a mains supply.
The sign has a dimming option which can be configured to reduce the brightness and power
consumption of the sign. This may be achieved either automatically according to the light falling on
an internal sensor, or by applying a separate brightness control voltage to the sign.
The message is almost invisible when the sign is switched off.
The sign may be used on its own or in conjunction with Lasermet’s interlock systems.
When the sign is used on its own, Lasermet offer a power supply and switch kit which enables easy
installation and operation.
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.
