What type of sprinkler head is required if it is installed 15 feet away from a unit heater?

In a situation where a sprinkler head is installed near a heat source, such as a unit heater, understanding the temperature rating of the sprinkler head is crucial for proper function and safety.

When a sprinkler head is located 15 feet away from a unit heater, it is important to consider the potential effect of heat on the activation temperature of the sprinkler. The intermediate temperature sprinkler is specifically designed to activate at a temperature range that is suitable for moderate heat exposure, typically around 135°F to 170°F (57°C to 77°C). This makes it appropriate for locations where there is some elevation in ambient temperature due to nearby heating appliances but not extreme heat that would require a high-temperature sprinkler.

Selecting an intermediate temperature sprinkler also ensures that it will operate effectively without being falsely tripped by the heat from the unit heater, which may occur if a lower temperature or standard temperature sprinkler is used. These other types of sprinklers might not be able to handle the conditions presented by the heater effectively and could either activate too early (in the case of low temperature) or not operate as needed (in environments where the temperature fluctuates).

Therefore, the choice of an intermediate temperature sprinkler in this scenario aligns with fire protection standards and is essential for ensuring that the sprinkler system
