Questions and answers
New never used, has alarm ! In yellow, 02 in yellow, 0.0%vol, please let me know how to fix alarm
To fix the alarm on a Bosean BH-4S, first identify the type of alarm:
- Low Alarm: Indicated by a yellow light, slow alarm tone, and vibration.
- High Alarm: Indicated by a red light, harsh alarm tone, and vibration.
Steps to fix the alarm:
1. Check Gas Levels: The alarm indicates gas concentration levels. Ensure the environment is safe and ventilated.
2. Reset or Acknowledge Alarm: If the alarm persists after clearing the gas, use the detector menu to reset or review alarm logs.
3. Calibrate if Needed: From the menu, select calibration or zero calibration if readings are inaccurate.
4. Contact Manufacturer: If the alarm continues without gas presence, there may be a fault. Contact the manufacturer or dealer.
Note: Avoid charging the detector in hazardous environments, as it disables gas detection during charging.
