  • Page 3: Introduction

    1. Introduction RA02G is an indoor sensor with smoking, noise, and anti-tamper detection. New functions such as power outage detection, sensitivity adjustment, audio alerts customization, and PoE splitter connection are now added. The new RA02G makes indoor monitoring easier and flexible than you ever imagined.

  • Page 4: Appearance

    ▲ The above figure is for reference only. The 12V PoE splitter is not included when purchasing RA02G. Note: (1) To adjust the sensitivity of the noise and smoking sensor, the user may use a small screwdriver to poke in the hole and slowly turn the knob.

  • Page 7: Data Report

    5. Data Report The device will immediately send a version packet report and a data packet with the IncenseSmokeAlarm, HighSoundAlarm, ShockAlarm, and PowerOffAlarm. Data will be reported by default setting before any configuration. Default setting: Max Interval = 0x0384 (900s) Min Interval = 0x0384 (900s) // The MinTime configuration is not available, but the MinTime must be configured a number greater than 0.
  • Page 8 2. Sensitivity Adjustment of Smoking and Noise Detection (1) Smoking detection (IncenseSmokeAlarm) (2) Noise detection (HighSoundAlarm) High High Sensitivity Sensitivity 4 levels Levels (every 45° for one level) The lower the HighSoundAlarmTriggerThreshold is, Sensitivity Level 1 > Level 2 > Level 3 > Level 4 the higher the sensitivity is.
  • Page 9 (3) The length of the audio alert is 15 seconds by default. When the audio alert sounds before smoking and vibration sensors, the device would report HighSoundAlarm=0 during the 15 seconds.

  • Page 18 Notes: (1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data. (2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value, the device reports according to MinTime interval.
