Advantages of Quick Response Fire Sprinkler

High Effectiveness:

Statistics show that sprinklers extinguish or contain fires early in up to 95% of cases, when designed and installed properly.

Reduced Damage:

Sprinklers focus water on the fire’s origin, usually using less water than manual firefighting methods.

Automatic Operation:

They don’t rely on human intervention; activation occurs when the temperature threshold is reached.

Insurance Benefits:

Many insurers offer lower premiums for buildings with certified sprinkler systems.

Types of Quick Response Fire Sprinkler

 

Pendent:

Hangs down from piping with the head exposed

01

Concealed pendent:

Installs in ceilings with the head hidden from view behind a cover plate

02

Upright:

Often used with exposed piping, these heads point upward to spray around obstructions

03

Horizontal sidewall:

Mounts to piping behind a wall with the head parallel to the ground.

04

Concealed horizontal sidewall:

Same as above, but hidden behind a cover plate.

How Quick Response Fire Sprinkler Work

 

Every sprinkler head contains a thermally sensitive component, typically a glass bulb filled with glycerine. When the surrounding temperature reaches the bulb’s designated limit (for example, 68°C, 79°C, 93°C, etc., depending on the sprinkler rating), the liquid expands and shatters the glass. This allows water in the piping to discharge through the deflector, targeting and suppressing the flames.

 

Importance Of Quick Response Fire Sprinkler
FM Approved Sprinkler Heads manufacturers

Rapid Response:

Sprinklers activate within moments of detecting heat, often before the fire department arrives.

 

FM Approved Sprinkler Heads suppliers

High Reliability:

According to the NFPA (National Fire Protection Association), sprinklers operate in 92% of reported structure fires where they are present.

Localized Suppression:

Only the sprinklers closest to the fire activate, reducing water damage.

Reduced Fatalities and Injuries:

The risk of death in a fire is reduced by about 85% when sprinklers are present.

 

Maintenance and Testing of Quick Response Fire Sprinkler

Maintaining your fire sprinkler system is not optional—it’s a legal requirement in most jurisdictions. Regular inspections include:

 
 

Monthly:

Visual checks of valves and gauges

 
 
 

Quarterly:

Alarm system and valve operation

 
 
 

Annually:

Full system inspection and flow tests

 

 

Components of Quick Response Fire Sprinkler

 

Sprinkler Heads

The most obvious part of the fire sprinkler system is the sprinkler heads themselves, because quite often these are the only visible parts in public areas of a building. These devices are strategically placed throughout a building to ensure appropriate coverage based on risk assessment and design requirements.

 

Valves

Valves are critical components in a fire sprinkler system. They control the flow of water to the sprinkler heads and are essential for the system’s operational integrity.

 

Air Compressors

In dry-pipe fire sprinkler systems (which may include completely dry systems, those which are dry only for certain periods – alternate, or those which are dry only in certain areas – tail-end), air compressors maintain the necessary air pressure in the pipes.

 

Pump Initiation Boards

Pump initiation boards are vital in many types of (pumped) fire sprinkler system for maintaining the correct ‘standing pressure’ (by way of a jockey pump) and for activating the main fire pump/s when a fire is detected.

 

Booster Pumps

Booster pumps play a significant role in maintaining adequate water pressure within the fire sprinkler system, and for providing the correct pressurised flow at times of sprinkler activation.

 

Pressure Gauges

Pressure gauges are essential for monitoring (water or air) pressure within a fire sprinkler system. Regular monitoring aids maintenance, problem-solving and helps in ensuring that the system is always ready to respond to a fire emergency.

 

Switches

Flow and pressure switches have multiple functions – they may send a warning or alarm signal to a separate panel, or they may operate a pump or other part of a system. Periodic testing, especially of zone flow switches and fire pump pressure switches, is crucial.

 

 

Application of Quick Response Fire Sprinkler

 

 

Commercial Buildings:

Office buildings, hotels, restaurants.

 

Residential Complexes:

Apartment buildings, where high occupancy is common.

 

Healthcare & Assisted Living:

Hospitals, nursing homes, assisted living facilities.

 

 

FAQ

Q: What are quick response sprinklers used for?

A: Reliable quick response sprinklers are ideal for protecting light and ordinary hazard applications such as office buildings, hotels, schools, and restaurants to control the spread of fire.

Q: What is the difference between standard response sprinklers and quick response sprinklers?

A: Physically, the only difference between a standard response fire sprinkler and a quick response fire sprinkler 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.

Q: Can you mix standard and quick response sprinkler heads?

A: If the vendor were to use a Quick Response (QR) sprinkler head in the same compartment as existing SR sprinkler heads, the requirements of NFPA 13 would require all sprinkler heads in that compartment be changed to QR sprinkler heads.

Q: What is the RTI of a quick response sprinkler system?

A: Quick Response (QR) Sprinkler: A type of spray sprinkler that has a thermal element with an RTI of 50 (meter-seconds)1⁄2 or less and is listed as a quick-response sprinkler for its intended use.

Q: How long are quick response sprinkler heads good for?

A: The latest version of NFPA 25 stipulates that quick response fire sprinklers should be tested 20 or 25 years after installation (depending on your jurisdiction) and must be repeated every 10 years after the initial test.
