USA market
For LIPs (Laser Illuminated Projectors) installed in the USA market other restriction zone conditions apply.
LIPs for installation in restrained environment (cinema theaters) shall be installed at height vertically above the floor such that the bottom
plane of the hazard distance zone shall be no lower than 2.5 meters above the floor. Horizontal clearance to the hazard distance zone
shall be not less than 1 meter.
LIPs for installations in unrestrained environment (large venues,..) shall be installed at a height vertically above the floor such that the
bottom plane of the Hazard distance Zone shall be no lower than 3 meters above the floor. Horizontal clearance to the hazard distance
zone shall be not less than 2.5 meters. Any human access horizontally to the Hazard Zone, if applicable, shall be restricted by barriers. If
human access is possible in an unsupervised environment, the horizontal or vertical clearances shall be increased to prevent exposure to
the hazard distance zone.
In addition for temporary installations (e.g.: rental and staging, lease, events
…
) the following requirements apply:
•
This product can only be installed by Barco or sold or leased only to valid laser light show variance holders. In other words our
installers are required to have an approved laser light show variance. Such installers may currently hold a valid variance for production
of Class IIIb and IV laser light shows and/or for incorporation of the RG3 LIPs into their shows. Dealers and distributors are also
required to obtain a valid laser light show variance.
•
This product shall be located in such a way that all propagating beam paths within the Restriction Zone, and the audience can be
directly observed at all times.
•
Effects other than front or rear screen projections shall not be performed.
•
Communication shall be maintained with other personnel assisting in surveillance of the LIP projection.
•
In the event of any unsafe condition, immediately terminates (or designate the termination) of LIP projection light.
Install one or more readily accessible controls to immediately terminate LIP projection light. The power input at the projector side is
considered as a reliable disconnect device. When required to switch off the projector, disconnect the power cord at the projector side. In
case the power input at the projector side is not accessible (e.g. truss mount), the socket outlet supplying the projector shall be installed
nearby the projector and be easily accessible, or a readily accessible general disconnect device shall be incorporated in the fixed wiring.
Laser light shows can be requested via the FDA online eSubmitter portal or via FDA Form FDA Form 3147 referencing to Barco
’
s
variance approval xxxx-xx-xxx.
The installation checklist for laser illuminated RG3 projectors must be fully completed after the installation and sent to [email protected].
This checklist can be downloaded from the Barco website. Only when the installer is a valid laser light show variance holder the checklist
should not be sent to Barco.
1.4.3 HD for fully enclosed projection systems
HD
Hazard Distance (HD) is the distance measured from the projection lens at which the intensity or the energy per surface unit
becomes lower than the applicable exposure limit on the cornea or on the skin. The light beam is considered (to be) unsafe
for exposure if the distance from a person to the light source is less than the HD.
Restriction Zone (RZ) based on the HD
The projector is also suitable for rear projection applications; projecting a beam onto a defuse coated projection screen. As displayed in
Image 1-4 two areas should be considered: the restricted enclosed projection area (RA) and the observation area (TH).
