NEMOTO NIS-09C Smoke Sensor Manual
The NIS-09C is an ion‑type smoke sensor with a one‑source two‑chamber design, using a 241Am radiation source. Key electrical specs include a DC 6.0‑18.0 V supply (max 24 V) and a 5.6 ± 0.4 V output, with a current draw of 27 ± 3 µA and sensitivity of 0.6 ± 0.1 V. The sensor measures 22.0 × 42 mm and weighs 12 g.
The manual details environmental limits, long‑term stability tests, vibration and drop tests, and safety precautions such as using a measurement instrument with >10^14 Ω impedance, keeping leads suspended, sealing with epoxy, and shielding to minimise leakage. Contact information for SUNSTAR (the distributor) is also provided. This manual is written in Chinese.
