NIS-5A
NIS-05A is also an ionization type smoke sensor. The radioisotope 241Am is used as the radiation source, but the radioactivity is about 55% of NIS-09C and the whole sensor is covered with metallic housing which eliminates the fear of radiation leakage. The pin location and the performances are compatible to sensors produced by other manufacturer than Nemoto.
