Public Facility Protected-Area CO₂ Gas Detector Installation — Electrical Room & Generator Room

This article covers CO₂ gas detectors and a gas concentration status board installed in a protected area. A protected area is a zone where fire-detection equipment normally monitors and controls for fire, and where suppression equipment activates to extinguish a fire when one occurs. For worker safety when working inside a protected area, installing oxygen or CO₂ detection and alarm equipment is essential.

CO₂ gas detector installation

This site had CO₂ gas detectors installed throughout the electrical room, UPS room, generator room, oil tank room, and clean-agent storage room, all of which are designated as protected areas, and an integrated monitoring status board was also installed at the central control room so that gas leaks can be detected across all of these areas.

Electrical room CO₂ status board installation

A gas status board was installed so that workers stationed in the control room can check the CO₂ level inside the electrical room. The alarm activates when the CO₂ concentration reaches 1.5% VOL or higher!

CO₂ gas concentration display

A gas concentration monitoring display was also installed at the main entrance to the electrical room.

Generator room gas concentration detector installation

The wiring for the gas leak detector inside the generator room was finished neatly using steel conduit. This site was quite challenging, as the total cable run exceeded 200 m.

FIX800 CO₂ detector

Ready for commissioning after installing the FIX800 CO₂ gas detector! Since CO₂ gas is denser than air, it is installed at a height within 50 cm from the floor.

Generator room protected-area gas detector installation

A FIX-DS gas status board was installed above the entrance to the generator room, and thanks to its high-performance LED module, visibility is excellent even from a distance.

Protected-area CO₂ concentration leak management status board

An integrated monitoring status board was installed at the central control room to monitor the CO₂ gas concentration inside the electrical room, clean-agent storage room, generator room, oil tank room, and UPS room, all of which are designated CO₂ protected areas.

Electrical room gas concentration detector commissioning

After installation was completed, a response test and commissioning were carried out using standard gas. We explained how to operate the gas detectors and their maintenance requirements, completing this challenging installation project.

CO₂ clean-agent room gas detector installation

Regular follow-up visits are made after installation to support maintenance of the gas detectors and status boards. If you have any questions about installing CO₂ gas detectors, please feel free to reach out anytime!
