Climate suitable and fire-resistant

• In case of the risk of condensation (different climatic conditions inside/outside), we recommend using this T-Rspion. The T-Rspion is tested according to standard EN 1121. Climate class C D
• Climate C long-term test of 28 days, indoor temperature 23 °C / outdoor temperature 3 °C
• Climate D 24-hour test, indoor temperature 23 °C / outdoor temperature -15 °C
• This T-Rspion is also approved for fire protection doors according to standard B 3850, El 30 (formerly T30), max. T-R plate drilling: 14.5 mm

To avoid any issues (e.g., condensation of the T-Rspion), certain operating conditions must be observed. The T-Rspion was tested between two different climates - testing procedures based on a relative humidity (RH) of max. 48%, which corresponds to a healthy indoor climate:

• Test climate D: -15 °C outside, 23 °C inside - 30% RH - with high humidity -15 °C outside, 23 °C inside - 45% RH
• Test climate C: 3 °C outside at 85% RH, 23 °C inside at 30% RH
• with high humidity 3 °C outside at 85% RH, 24 °C inside at 48% RH

NOTE: Failure to comply with or exceeding the data specified in the test, especially exceeding the relative humidity in the rooms, may lead to condensation of the T-Rspion despite thermal separation.
