Position paper on Thermographic Fire Detectors (TFD)

The use of thermographic fire detectors (TFD) is increasing. However, there is no published European standard for TFD cameras while ISO 7240-33 is still under preparation. 

TFD cameras can respond to flames and can be certified in accordance with EN54-10 (Flame detectors - Point detectors) as flame detectors. The essential characteristics of EN 54-10, which are fulfilled by a TFD solution, are in this case listed in its DoP.

If the product is used as a flame detector, installation rules for flame detectors must apply in any case. If the product is not used as a flame detector, some confusion and problems may arise in the market on the meaning of the certification. For this reason, Euralarm is providing the following recommendations.
