How do fire sprinkler systems work?

Your server room facility may include sprinkler system components. The sprinkler head will contain a bulb with a coloured liquid inside that acts as a plug to prevent water from escaping. Heat rises and as the temperature increases from the fire, the heat expands the liquid which expands and eventually forces the bulb to burst, releasing the water in the sprinkler system. There are different coloured liquids for different temperature triggers including: orange, red, yellow, green, blue, purple and black. Sprinkler systems cannot be activated by smoke or dust even though the bulbs themselves are designed to be very fragile. Even tampering can set them off.
