Standards assert that the good condition of a lightning protection system should be ensured over time. Therefore the standard UNE 21.186:2011 establishes, depending on the protection level of the installation, different periodicities for visual and complete inspection.
The main difference between a visual and a complete inspection is if they include checking the correct working of the ESE air terminal. Up to date, in general, such check could be done in situ with a portable device or even sending the air terminal to the manufacturer, depending on the case. Both methods require to approach the air terminal with appropriate security conditions, using auxiliary lifting means and therefore increasing the cost of the installation maintenance.
DAT CONTROLER® PLUS + AT REMOTE TESTER Air Terminal finally solves this question, making this task easier and safer: it incorporates a remote tester, powered solely by solar energy and with communication by radiofrequency, for checking at any time, with a simple remote control at a distance of up to 100 meters, that the triggering device works properly.
For optimal operation, it is essential to locate the air terminal caring that the solar panel of the emitter is oriented to better receive sunlight. Besides, the emitter should be directed to an accessible place, avoiding obstacles and electromagnetic interferences thus letting the receptor device to establish easily communication via radiofrequency. Once these basic requirements are accomplished the system is very easy to use, since it does not require any previous configuration or maintenance.
Thanks to this new model, complete periodic inspection become much easier, avoiding the risks and complications derived of reaching areas of difficult access an earning time and security of the workers.
Such ease for use makes that the inspections can be done not only when established by the standard but also at any moment deemed appropriate, being recommendable after a lightning strike to the installation. For better determining rightly such impact, the best options is to provide the installation with a counter that, if possible, registers information not only about the number of strikes to the installation but also about the date, time, amplitude and polarity of the flash. The smart lightning counter ATLOGGER provides this information.
