Applied Markets
Installed Gases
Project Details
Hello. Today's post may be one of the most useful field application cases we have shared so far.
We have occasionally received inquiries about gas detectors for septic tank rooms, and this is the first time we have installed a gas detector at an actual septic tank site.
Many installed-type detectors exist on the market, but we exclusively use the FIX800.
Key features of the FIX800 include full remote-control operation for customer convenience, a built-in warning light optimized for confined spaces, and support for up to 4 sensors in a single unit.
This site was an underground septic tank room at a department store.
The customer requested a gas detector to be installed inside the septic tank room, along with a display board so that gas concentration could be checked before entry.
A site survey was carried out in advance to confirm the installation points for both the detector and the display board.
We also checked the communication distance between the two points and prepared sufficient corrugated conduit and other materials accordingly.
Through repeated installations, we continue to make improvements to our process.
The detector and display board can now be installed as a set, with the display board supplying power to the detector. This removes the need for separate power wiring for the detector, simplifying the installation, and allows the detector to be installed even in locations without a power supply, such as gas storage areas or explosion-proof zones. Installation of the detector itself was completed quickly, secured with just three screws.
Next, we moved to the display board installation point.
The display board was installed near the exit door at the top of the stairs leading out of the septic tank room.
Since the power outlet was conveniently located close to the requested spot, the display board installation was also completed cleanly and easily.
Here is a brief explanation of how the system works: the oxygen concentration measured by the detector in the septic tank room is transmitted in real time to the display board via RS485 communication.
If the oxygen concentration drops due to a gas leak, the detector itself triggers an alarm, and the display board's text changes from green to red, helping to protect worker safety.
After installation, we tested the system using a portable standard gas and provided product training to the facility's operations manager.
That concludes this installation case for a septic tank gas alarm and oxygen detector for confined-space suffocation prevention.
Frequently Asked Questions (FAQ)
Q1. What does the FIX800 measure in this installation?
The FIX800 measures oxygen (O₂) concentration inside the confined-space septic tank room.
Q2. How many sensors can a single FIX800 unit support?
The FIX800 supports up to 4 sensors in a single unit.
Q3. How does the detector communicate with the display board?
The measured gas concentration is transmitted to the display board in real time via RS485 communication.
Q4. What happens if the oxygen concentration drops due to a leak?
The detector triggers an alarm, and the display board's text changes from green to red to alert workers before entry.
Q5. Can the display board supply power to the detector?
Yes. When installed as a set, the display board can supply power to the detector, removing the need for separate power wiring and allowing installation even where no power source is available.
