Fire Sprinklers: Standard Response vs. Quick Response

Different types of sprinkler are designed for different types of buildings, and choosing the right type is essential for maximizing your fire protection. There are six primary characteristics that define a sprinkler’s ability to control or extinguish a fire:

  • Thermal sensitivity
  • Temperature rating
  • Orifice size
  • Installation orientation
  • Water distribution characteristics
  • Special service conditions

In addition, there are two types of sprinkler heads: standard response and quick response. In this post, we are going to compare the two types of sprinkler heads.

Standard Response (SR) Sprinkler Heads

Standard response sprinkler heads are the most common types of sprinkler heads. They are designed to pre-wet nearby materials before the fire reaches them while simultaneously cooling adjacent areas to prevent the spread of fire.

Because the fire is contained to a limited area, these heat-activated sprinklers only sprinklers directly above the fire operate.

Quick Response (QR) Sprinkler Heads

Quick response fire sprinkler heads are primarily used in light hazard applications and have a higher discharge pattern than standard response fire sprinkler heads. By discharging water higher up on the ceiling, QR sprinkler heads keep the ceiling at a lower temperature, preventing flash-over and increasing your chance of survival during the fire.

QR fire sprinkler heads are now the standard for installation in health care facilities, assisted living facilities, and residential occupancies.

Differences Between Standard & Quick Response Sprinkler Heads

The biggest difference between a quick response and a standard response sprinkler head is the temperature at which the sprinkler head activates. Quick response sprinkler heads activate at slightly lower temperatures than standard response head, suppressing the spread of fire more quickly.

Other than that, the only difference between a standard and quick response fire sprinkler head is the size of the bulb—standard response sprinklers have a 5 mm glass bulb, while quick response fire sprinklers have a 3 mm glass bulb.

Ceiling height is a key factor and you should always take into consideration the temperature of the environment during all the seasonal months of the year. The size of the spray area should be a primary concern when you install a specific type of sprinkler head.

Depending on what type of building you are outfitting, sometimes substituting several standard response sprinkler heads for a fewer amount of quick response sprinkler heads may be more of a cost-effective approach depending on how large or small of an area you are working in.
