PURPOSE: A distribution panel fire detection controller is provided to display an alarm to enable an operator to visually recognize a sign of fire in advance, thereby preventing fire. CONSTITUTION: A distribution side power line temperature detection part detects a power distribution line temperature of a switch. The distribution side power line temperature detection part converts the temperature into a resistance value corresponding to a measured temperature. A first control part (40) checks a sign of fire and provides a first alarm display and fire-extinguisher actuation signal. A second control part (50) checks a sign of fire and provides a second alarm display and fire-extinguisher actuation signal. A first and a second alarm display activation part (60,70) turn on/off an alarm display part of each step. |
