Subway Platform RF Electromagnetic Field Strength Test

Abstract:

Since in their tenders for subway fire alarm system contracts some fire detector manufacturers recently claimed that the RF electromagnetic field strength to which their products can resist is much higher than the requirements of the relevant national technical standards on fire, we have conducted tests on the RF electromagnetic field strength around the fire detectors installed on the platform of a number of selected subway stations in Guangzhou, and the performances of the electromagnetic radiation analyzer used for the tests are strictly in compliance with the specified use conditions for fire detectors installed on the platform in subway stations. The test results show that the RF electromagnetic field strength applied in the RF radiated immunity test as specified in relevant national standards conforms to the current application conditions.
