What does WANDI Korea do?

WANDI Korea is the official Korean distributor of WANDI environmental and gas measurement instruments, operated by RS Korea Co., Ltd. We provide sales, calibration, repair, installation, and technical support for portable and fixed multi-gas detectors and air quality monitoring systems, exporting to more than 20 countries with over 5,000 delivery records.

What products do you offer?

We supply portable multi-gas detectors (EDW100, EDW500, Gas Tiger series), fixed multi-gas detectors (FIX800, FIX900, FIX-AP), air quality monitoring systems (FIX5000), and gas leak detectors (GLD series) for industrial safety and environmental measurement.

Which gases can be measured?

Our instruments measure oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), combustible gases (EX), carbon dioxide (CO2), ammonia (NH3), and volatile organic compounds (VOC), among other hazardous and combustible gases found on industrial sites.

Yes. Beyond product sales, WANDI Korea provides in-house and national certified calibration, repair, installation, and ongoing technical support. Calibration and repair requests can be submitted through the quote/calibration/repair pages on our website.

How can I get a quote for a gas detector?

You can request a quote directly through the quote page on our website or through a nearby dealer. Let us know your application and target gases, and we will recommend a suitable model.

In which fields are the products used?

They are used across a wide range of industrial sites including laboratories, factories and plants, hospitals, military facilities, livestock and wastewater treatment, and construction sites for worker safety and environmental monitoring.

FIX800 Fixed CO₂ Detector with LED Display Board — Fire Suppression Agent Room Installation (Seoul/Gyeonggi-do)

This case covers a FIX800 fixed CO₂ (carbon dioxide) detector installation in a fire suppression agent room.

FIX800 — Product Overview

The FIX800 fixed CO₂ detector is approximately the size of an adult's open hand and is typically wall-mounted horizontally.

The circular section at the bottom of the FIX800 houses the CO₂ sensor. It continuously measures carbon dioxide concentration in the surrounding air and displays the reading on screen.

When the detected CO₂ concentration exceeds the configured threshold, the beacon on the right side of the unit triggers audible and visual alarms.

Integrated Monitoring — FIX800 + LED Display Board

For this installation, the FIX800 and LED display board were configured as an integrated monitoring system. CO₂ readings measured by the FIX800 are transmitted to the display board and shown in real time.

Most fire suppression agent rooms are enclosed by thick concrete walls, making power wiring difficult. When used with the LED display board, power can be supplied to the FIX800 directly from the display board — significantly simplifying installation.

On-Site Installation

Most buildings and facilities have a fire suppression agent room in the basement containing stored CO₂ gas. A leak can cause rapidly lethal CO₂ concentrations — continuous monitoring with a fixed detector is essential.

The FIX800 was installed inside the suppression room and an LED display board was mounted at the entrance. Workers can check internal CO₂ concentration before entry, enabling effective asphyxiation prevention. Installation in fire suppression agent rooms is straightforward — up to 2 points per day can be completed.

Frequently Asked Questions

Q1. Why is a CO₂ detector mandatory in fire suppression agent rooms?

Suppression agent rooms store high-pressure, high-concentration CO₂. A leak causes concentrations to rise rapidly — and since CO₂ is colorless and odorless, it cannot be detected by smell. At high concentrations it causes rapid loss of consciousness and death. Under Korea's OSHA, such rooms are classified as confined spaces requiring continuous monitoring.

Q2. What is the advantage of supplying power from the display board to the FIX800?

Thick concrete walls make it difficult to run separate power cables into the suppression room. By mounting the display board at the entrance and running power to the FIX800 through the display board's connection, the electrical installation is simplified — reducing both installation time and cost.

Q3. What symptoms does CO₂ suppression agent exposure cause?

At 2–3%: headache and breathing difficulty. Above 5%: severe respiratory distress and impaired consciousness. Above 10%: sudden loss of consciousness. Above 15%: death within minutes. Suppression agent discharge can instantly reach these concentrations, making alarm systems essential.

Q4. Can the FIX800 detect other suppression agent gases besides CO₂?

Yes. The FIX800 supports up to 4 sensors. For clean agent systems (HFC, FK-5-1-12, etc.), an O₂ sensor can be added to detect oxygen displacement caused by the suppression agent. The appropriate sensor combination depends on the specific agent — consult a specialist before specifying.

Q5. Is explosion-proof specification required for fire suppression agent rooms?

CO₂ itself is non-flammable, so explosion-proof specification is not generally required. However, if the room is adjacent to areas handling flammable materials, site-specific risk assessment may require Ex-rated equipment. Always confirm with the site safety officer before installation.
