The Difference Between Quick and Standard Response Fire Sprinkler HeadsFire Sprinklers
Fire sprinklers are an elemental aspect of fire protection. But did you know there are different kinds of fire sprinkler heads? Different types of sprinkler heads are designed for different environments—do you know which type your building requires? Which one you use can make or break your overall fire protection.
There are six main characteristics that define a sprinkler’s ability to control or extinguish a fire. You will be able to select a sprinkler head based on how your business environment matches these traits:
- Thermal sensitivity
- Temperature rating
- Orifice size
- Installation orientation
- Water distribution characteristics
- Special service conditions
There are two types of sprinkler heads: standard response and quick response. The distinction between the two lies mostly in the type of hazard the sprinkler will serve to extinguish. Continue reading to find out what type of sprinkler head is best suited for your business!
Standard Response (SR) Fire Sprinkler Heads
Standard response sprinkler heads wet and cool the area surrounding a fire to prevent it from spreading. This approach aims to suppress the fire’s source to slow the spread of flames. Once the fire’s fuel is eliminated, it goes out. Standard response fire sprinklers are individually activated, meaning only sprinkler heads directly above the fire will activate. Because of their precision, SR fire sprinkler heads are best suited for commercial or industrial buildings such as factories or warehouses.
Quick Response (QR) Fire Sprinkler Heads
Quick response sprinkler heads are most appropriate for light hazard applications. Water discharges higher up on the ceiling, which cools the ceiling to deter the fire from rising. This increases the odds of survival as people attempt to evacuate and prevents flash-over. QR fire sprinkler heads are typical in high-density environments such as health care facilities, assisted living facilities, office buildings, or schools.
Differences Between Standard and Quick Response Sprinkler Heads
Activation temperature is the most notable difference between quick response and standard response sprinkler heads is their activation temperatures. As the name implies, quick response sprinkler heads activate slightly more quickly due to their increased sensitivity.
The only physical difference between a quick response fire sprinkler and a standard response fire sprinkler is the size of the bulb— quick response fire sprinklers have a 3-mm glass bulb, while standard response sprinklers have a 5-mm glass bulb. The smaller bulb increases the sprinkler’s thermal responsiveness, enabling a quicker activation time.
A faster response time might make it seem like QR sprinklers are superior, but they aren’t always the right choice. There are other key factors to consider when choosing a sprinkler head, including:
- Ceiling height
- Ambient temperature throughout the year
- Size of the area to be protected
All of these elements will determine whether a standard response or quick response sprinkler heads will be more effective for your business. Smaller areas or tall buildings are more suited to quick response sprinkler heads, whereas higher ceilings in larger areas will benefit from standard response sprinkler heads.
