Products Description
CA-FIRE Standard Response 68 °C Fire Sprinklers
As a core terminal of automatic sprinkler systems, the Standard Response 68°C Fire Sprinkler operates on the "glass bulb rupture activation" principle: a liquid-filled glass bulb is installed inside the sprinkler. When the ambient temperature rises to 68°C (±3°C), the liquid in the bulb expands due to heat, causing a sudden increase in pressure that ruptures the bulb. This dislodges the sprinkler's sealing component, allowing pressurized water from the fire piping to diffuse evenly through the deflector, forming an effective water coverage area with a radius of 1.5–2.5 meters. Its water flow intensity meets the "standard response" requirements specified in standards such as GB 5135.1 (China), UL 199 (US), and FM 1300 (US), with a Response Time Index (RTI) of ≥80 (m·s)^0.5.
Key parameters and design details of the product are as follows:
Activation Temperature: 68°C (a universal threshold for general environments, preventing false activation at low temperatures and ensuring timely response at high temperatures).
Response Type: Standard response (compatible with fire systems in most non-high-risk areas, with water release speed matching conventional fire scenarios).
Connection Size: Common DN15/DN20 (threaded connection, compatible with mainstream pipes such as galvanized steel pipes and stainless steel pipes).
Material & Structure: The valve body is made of brass/stainless steel (corrosion-resistant and anti-aging, suitable for water-based fire suppression media), and the deflector is made of ABS or metal (ensuring uniform water coverage).
Certification & Compliance: Certified by UL, FM, GB (China), CE (EU), and other regional standards, meeting fire safety regulations in different countries/regions.
Application Scenarios: Suitable for offices, shopping malls, hotels, residences, warehouses (non-high-temperature/high-humidity special areas), and light industrial plants. Not applicable to high-temperature or special-risk areas such as kitchens, boiler rooms, and hazardous material warehouses.
Products Features
CA-FIRE Standard Response 68 °C Fire Sprinklers
The 68°C activation threshold has been verified in numerous scenarios and is compatible with indoor ambient temperatures (≤25°C in winter heating, ≤40°C in summer heat) in most regions worldwide. It effectively avoids false triggers caused by ambient temperature fluctuations while responding quickly when the fire reaches 68°C in its early stages.
Standard Response for Strong System Compatibility
Compliant with "standard response" water flow characteristics, its Response Time Index (RTI) matches the pressure and flow design of most conventional fire sprinkler piping (e.g., wet-pipe automatic sprinkler systems). It can be directly replaced or newly installed without modifying existing systems, reducing engineering adaptation costs.
The valve body is made of brass or 304 stainless steel, which resists corrosion and water pressure impact, with a service life of 10–15 years. The glass bulb is made of high-compressive-strength material, eliminating the risk of rupture at room temperature and reducing the frequency of daily maintenance.
The Advantage of CA-FIRE Standard Response 68 °C Fire Sprinklers
Safety Adaptability: Balances "False Activation" and "Delayed Response"Compared to sprinklers with lower activation temperatures (e.g., 57°C), the 68°C threshold avoids false activation in scenarios such as winter heating or equipment heat dissipation. Compared to those with higher temperatures (e.g., 79°C), it triggers earlier before the fire spreads, reducing fire risk. It is the "optimal safety threshold" for general environments.
System Compatibility: Reduces Project Retrofit CostsMost existing buildings' fire piping is designed for "standard response" sprinklers. This product can directly replace old sprinklers without replacing pipe pumps or adjusting water flow indicator parameters. It is more compatible with traditional systems than "quick response" sprinklers, significantly reducing retrofit cycles and costs.
Reliability & Stability: Adapts to Complex Environmental ConditionsThe valve body material resists acid, alkali, and water corrosion (compatible with municipal tap water and fire-fighting water), maintaining stable performance even in humid (e.g., underground garages) or dry (e.g., office buildings) environments. The glass bulb's liquid formula has passed high-low temperature cycle tests, with no leakage or failure risks in the normal temperature range of -10°C to 60°C.
Cost Optimization: High Cost-Effectiveness Throughout the LifecycleThe product's procurement cost is lower than that of special-response sprinklers (e.g., quick response, ESFR). Due to its strong compatibility and low maintenance frequency, the total lifecycle cost (procurement + installation + maintenance) is 15–20% lower than similar products, making it suitable for large-scale batch applications (e.g., residential communities, large shopping malls).
Safety Assurance: Early Fire Suppression to Reduce LossesThe standard response water flow can quickly cover the fire source area when the temperature reaches 68°C in the early fire stage. The average fire suppression time is 80% shorter than manual fire fighting, effectively preventing the fire from spreading to surrounding areas. According to data from the National Fire Protection Association (NFPA), buildings equipped with this type of sprinkler can reduce fire property losses by over 60% and provide more time for personnel evacuation.
FAQ– CA-FIRE Deluge Alarm Valve
1. Why is 68°C chosen as the activation temperature?
68°C is the "universal threshold for general environments" in global fire safety standards: there is a sufficient safe temperature difference between the indoor ambient temperature (10–35°C) in most regions and 68°C, preventing false activation. Meanwhile, when the temperature of an early fire (e.g., solid combustible combustion) rises to 68°C, the fire is usually in the "initial spread stage." Triggering the sprinkler at this point maximizes loss reduction, aligning with the requirements for "temperature control in general areas" in standards such as GB 5135.1 and NFPA 13.
2. Is this product suitable for kitchens or boiler rooms?
No. Kitchens (where oil fume temperatures can exceed 100°C) and boiler rooms (where ambient temperatures often exceed 50°C) are "high-temperature special areas" and require sprinklers with higher activation temperatures (e.g., 93°C, 141°C). This product is only suitable for general environments without continuous high temperatures or special fire sources (e.g., offices, residences, ordinary warehouses).
3. Do sprinklers require regular maintenance? What is the maintenance cycle?
Regular maintenance is required, with recommended cycles as follows:
Routine Inspection: Visually check the appearance (no damage, no corrosion, no discoloration of the glass bulb) every quarter.
Professional Testing: Conduct pressure testing (to ensure no leakage from the valve body seal) by a fire protection maintenance unit every 5 years.
Replacement Cycle: After 10 years of use, it is recommended to replace the sprinklers in batches even if there is no visible abnormality (the liquid in the glass bulb may age over time, reducing activation sensitivity).
4. What is the difference between standard response and quick response sprinklers?
The core differences lie in response time and applicable scenarios:
| Comparison Item | Standard Response (This Product) | Quick Response |
|---|---|---|
| Response Time Index (RTI) | ≥80 (m·s)^0.5 | ＜50 (m·s)^0.5 |
| Activation Speed | Slower (for conventional fires) | Faster (for crowded/high-risk areas) |
| Applicable Scenarios | Offices, residences, ordinary warehouses | Hospitals, schools, shopping malls (crowded areas) |
| System Requirements | Compatible with conventional fire piping | Requires adaptation of pipe pumps and water flow indicators |
5. Are product certifications important? Can uncertified sprinklers be used?
Certifications are critical. Certifications such as UL and GB are core guarantees of "safety and compliance." Uncertified sprinklers may pose the following risks: ① Large deviations in activation temperature (e.g., labeled 68°C but actually activating at 75°C, delaying fire suppression); ② Insufficient pressure resistance of the valve body (rupturing and leaking when the piping pressure fluctuates); ③ Failure to meet local fire acceptance standards, resulting in the building failing fire approval. Therefore, only certified products should be used.
