Environmental requirements

Before installing or using your SMART Response interactive response system, review the following environmental requirements and compliance statements.

Temperature

SMART Response components can operate in the temperature range of 41°F to 95°F (5°C to 35°C). In addition, the product can withstand storage temperatures from -40°F to 120°F (-40°C to 50°C).

Humidity

SMART Response components can operate in up to 80% relative humidity, non-condensing.

Water and fluid resistance

SMART Response components are for indoor use only and don’t meet any salt-spray or water-ingress requirements. Don’t pour or spray any liquids directly onto SMART Response components. These liquids can get into areas where they can damage sensitive electronic components.

Dust and scratching

SMART Response components are for use in office and classroom environments, and they aren’t for industrial use where heavy dust and pollutants can cause malfunctions or impaired operation. They’re designed for pollution degree 1 (P1) as per EN61558-1, which is defined as “No pollution or only dry non-conductive pollution.”

Electrostatic discharge (ESD)

SMART Response components meet the requirements of EN61000-4-2 severity level 4 for direct and indirect ESD. No malfunction or damage up to 15 kV (both polarities) with a 330 ohm, 150 pF probe (air discharge). Unmated connectors meet 8 kV for direct (contact) discharge.

Conducted and radiated emissions

SMART Response hardware’s narrowband radiated electric field meets the limits for Class B performance, as defined in EN55022/CISPR 22.
