KOREASCHOLAR

Before the fire brigade arrives at the scene, the fastest way for occupants to suppress a fire is by discharging water through indoor hydrant outlets equipped with electronically controlled valves or motorized valves, as these systems are designed to open automatically. The experimental results are as follows: (1) Regarding electronically controlled valve operation times, system A had the shortest activation time of 6.74 seconds after the fire signal, while system J recorded the longest time at 13.4 seconds. (2) For angle valves (older model), system A had the shortest operation time of 10.2 seconds, whereas system I recorded the longest at 17.8 seconds. (3) For angle valves (newer model), system A again had the shortest activation time of 10.2 seconds, while system I recorded the longest at 17.8 seconds. (4) For motorized valve operation times, system A had the shortest activation time of 3.81 seconds, and system I the longest at 6.55 seconds. The observed differences in operation times are attributed to the fact that angle valves require manual operation by occupants, causing delays and slower valve opening, which increases activation times. In contrast, electronically controlled valves and motorized valves operate automatically, resulting in significantly shorter activation times.
