Common questions about our pendent fire sprinkler nozzles manufacturing and supply
A pendent fire sprinkler is a glass-bulb-triggered water-spray head installed facing downward from the ceiling. When the bulb reaches its rated temperature (68 °C, 79 °C, 93 °C, 141 °C or 182 °C), the liquid inside expands, breaks the bulb and releases water through the deflector to extinguish the fire below. Used in hotels, warehouses, hospitals, malls, offices, residential high-rises, data centres and industrial kitchens.
Quick-response (QR) pendent sprinklers use a 3 mm thin-wall glass bulb that activates within 20-30 seconds. Standard-response (SR) pendents use a 5 mm bulb activating in 40-60 seconds. QR is mandatory under NFPA 13R for light-hazard occupancies like hotels, hospitals, residential buildings and offices. SR is standard for warehouses, factories and ordinary-hazard spaces.
68 °C red covers normal rooms and corridors, 79 °C yellow for kitchens and boiler rooms, 93 °C green for mechanical and electrical rooms, 141 °C blue for industrial high-heat zones, 182 °C mauve for furnaces and ovens. We stock all five ratings and mix them per NFPA 13 Chapter 8 for a code-compliant occupancy design.
Standard K-factors are K5.6 (80 LPM/bar), K8.0 (115 LPM/bar) and K11.2 (161 LPM/bar) with 1/2" and 3/4" BSP male thread. Larger K14 and K16.8 ESFR variants are built-to-order with 2-3 week lead time for large storage warehouse projects.
Our fire-safety specialists help you select the correct K-factor, bulb temperature and finish for NFPA 13 and IS 15105 compliance. Call us or send drawings today.
