Hello from Raymond Korea. Before showing photos, we summarize the new CO₂ suppression management rules effective this October and the most common customer questions.

In short: (1) tighten management of CO₂ systems. (2) Control access and log entrants. (3) Install oxygen or CO₂ monitors for mis-discharge/leak scenarios. (4) Provide visible/audible warnings at entrances.

FAQ highlights: How many detectors?—sensors read the air touching the cell, not “per face area”; one interior transmitter is typical, two for very large protected zones. Under 100 cylinders?—small cylinder rooms may be exempt, but protected zones longer than ~10 m walking distance still need coverage. What is the 10 m rule?—it measures the escape path from the deepest protected volume to the exit.

Protected zones are piping-fed volumes that receive CO₂ during discharge—generator rooms, electrical rooms, UPS/battery halls, etc. Our FIX800 alarms audibly and visually; LEDs at doors show live status before entry.

Field photos: a power plant with bulk CO₂ in a standalone building. We installed interior FIX800 units and exterior LED boards with rigid steel conduit matching existing electrical finishes.

Ventilation was excellent; we selected points and installed CO₂ vs oxygen channels roughly 70:30 as customers prefer. SMD LED modules stay readable in direct sun—same technology as highway VMS boards.

Second point mirrored the first. After training and commissioning we used breath checks as quick sanity tests—each device ships with span calibration certificates. Typical crew throughput is ~2–3 points per day depending on distance.
