The pictures below show two different Tyco pendent fire sprinklers. The sprinkler on the left is the TY323 quick response in chrome. The sprinkler on the right is the TY325 standard response in brass. Notice the size difference in the bulbs - the TY323 is quick response, so the bulb is 3 millimeter, compared to the TY325's 5mm bulb. See how the deflector is curved downward? That is what helps direct the water out in a cone pattern.

The Tyco pendent fire sprinklers used in this example are available in a range of temperatures from 135 to 360 degrees Fahrenheit and three standard finishes: chrome, white, and brass. Other finishes are available upon request.
