What is the temperature setting for the most common sprinkler temperature sensor?

The temperature setting of 165 degrees Fahrenheit is commonly used for standard sprinkler temperature sensors, as it suits most types of occupancies encountered in fire protection systems. At this temperature, the sensor will trigger the sprinkler system to activate, allowing for a timely response to a fire situation. This temperature threshold is especially effective in protecting against the rapid spread of fire, which is crucial for safeguarding both life and property.

In many applications, the choice of temperature rating takes into consideration the specific type of environment the sprinkler is installed in, including factors such as the ceiling height, potential heat buildup, and the nature of combustibles present. The 165-degree sensor is a balanced option, providing both adequate response to fire and ensuring that false activations are minimized due to normal heat variations in the environment.

Other temperature settings, although applicable in various circumstances, are typically specified for unique conditions or different types of applications. For instance, lower settings might be used in places where rapid heat accumulation is expected, while higher settings may be reserved for areas requiring delayed activation due to specific temperature profiles.
