Safety and warning guidelines
Read all safety and warning guidelines before installing or operating the device.
This product must be operated in an environment that meets the operating range specification. Use
only the attachments and/or accessories recommended by Christie. Use of others may result in the
risk of fire, shock, excessive UV exposure, or personal injury.
CounterAct is a regulated pesticide device. The United States Environmental Protection Agency (EPA)
regulates pesticide devices under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). EPA
Establishment Numbers are noted on the label.
Any references to disinfection and disinfecting are referring generally to the reduction of pathogenic
bioburden and are not intended to refer to any specific definition of the term as may be used for other
purposes by the U.S. Food and Drug Administration or the U.S. Environmental Protection Agency.
The CounterAct device can produce small amounts of ozone during regular operation. When designing
the system, local regulations must be reviewed to ensure system compliance given the volume of the
space, characteristics of ventilation, access, and other factors.
The device may be used when humans are present but it is not intended to be used on humans, to
treat human disease, or otherwise be used as a medical device. Do not use the device for other than
the intended use.
Warning! If not avoided, the following could result in death or serious injury.
• The pathogen-reducing efficacy of Christie CounterAct products with patented Care222
technology and their use in occupied spaces is dependent on proper installation and operational
specifications, in accordance with American Conference of Governmental Industrial Hygienists
(ACGIH) guidelines.
• UV-C HAZARD! UV-C emitted from this product. Avoid eye and skin exposure to the unshielded
product. Follow all installation and operation instructions.
• Christie CounterAct products with patented Care222 technology are not for use as or for medical
devices.

surfaces, and protection from line-of-sight exposure to UV radiation in occupied spaces located
above the equipment mounting area (for example, upper floor balconies, open staircases, and so
on).
• UV-C OR OPTICAL RADIATION HAZARD! The installer must conduct an assessment of irradiance
or illuminance levels in the surrounding occupied space prior to occupancy to ensure people will
not be exposed to excessive UV or optical radiation during operation of the device.
• UV-C OR OPTICAL RADIATION HAZARD! Follow the manufacturer’s recommendations for
selecting appropriate ceiling and wall finishes as UV and optical radiation can be reflected by
surrounding surfaces such as ceilings and walls and reflective properties of surfaces can vary
widely.

CounterAct overview
CounterAct is a commercial UV disinfection fixture containing Ushio Inc.’s patented Care222® lamps
that emit far-UVC 222nm light, shown to significantly reduce surface pathogens in occupied and
unoccupied indoor spaces. Care222® is based on far-UVC germicidal technology that may also be used
around people and it is the only product with a proprietary filter that prevents longer UVC wavelengths
from being emitted.
The CounterAct fixtures are installed in the ceiling throughout a space. The light spreads out in a fixed
cone size. Therefore as the ceiling height increases or decreases the output power must be adjusted
up or down respectively. The lamps cannot be dimmed and are only capable of being in the fully on or
off state. Operating modes for CounterAct comply with the UV Threshold Limit Values (TLV) outlined
by the American Conference of Governmental Industrial Hygienists (ACGIH). The TLV is measured as a
time-weighted average for a conventional eight-hour workday.
Key features
Understand the important features of CounterAct.
• Ushio Care222® B1 lamp module
• BLE Mesh communication technology
• Android control application
• Central power coupler for easy servicing
• Three-finger hold design for single-handed service

Identify the recommended order for installing and setting up the components of the CounterAct
system.
1. Plan the layout and power for the site (on page 21).
2. Download and install the CounterAct application (on page 23) on a tablet.

to physically mounting the fixture in the ceiling. Adding one fixture at a time avoids
confusion between fixtures.
