The TYCO TY5130 is the upright model of the K11-231FRB series, with a K 11.2 discharge coefficient and 3/4″ NPT thread, quick response and standard coverage, operated by a glass bulb 3 mm. It is designed for high-piled storage and high-density applications, in lieu of K 5.6 or K 8.0 standard spray sprinklers. Installed above the pipe with the deflector facing up. For where the sprinkler sits in the whole system, see the complete guide to sprinkler systems in Saudi Arabia.
In short
- Model (SIN): TY5130 — Upright.
- Discharge coefficient K 11.2, 3/4″ NPT connection.
- Glass bulb 3 mm, quick response.
- Temperature ratings in the datasheet: 68 / 79 / 93 / 141 °C.
- Maximum working pressure: 175 psi (12.1 bar).
- Series approvals: UL, C-UL, FM, VdS, LPCB (per Table C). The approval of each model, finish and rating is in the approvals table of datasheet TFP345.
How this sprinkler works
The glass bulb contains a fluid that expands when exposed to heat. When the rated temperature is reached, the fluid expands enough to shatter the bulb, the sprinkler opens and the deflector spreads the water over the fire area.
Installed above the pipe with the deflector facing up. Quick response means the thermal element reacts faster, so the sprinkler operates earlier than a standard-response sprinkler of the same rating.
Models in the series
| SIN | Orientation | K-factor | Thread |
|---|---|---|---|
| TY5130 — this model | Upright | 11.2 | 3/4″ NPT |
Links to the other models are in the “Similar models” table below. The choice of model comes from the hydraulic calculation, hazard classification and installation method in the project design.
Application notes
- For in-rack use it becomes an intermediate-level sprinkler with the G6/S3 guard and shield; where at risk of mechanical damage, use the G6 guard. The 79°C rating is available in chrome for Asia only.

The critical point: wrench and guard
Tighten only with the W-Type 3 wrench at 10 – 20 lb-ft; only the guard specified in the datasheet may be used.
Installation steps
- Inspect before installing: never install a sprinkler whose bulb is cracked or has lost liquid.
- Install the sprinkler in its correct orientation (Upright) as shown in the datasheet — never reversed.
- Apply pipe-thread sealant to the threads, then hand-tighten the sprinkler.
- Finish with the specified wrench (W-Type 3) within 10 – 20 lb-ft (13.4 – 26.8 N·m). Higher torque can distort the inlet and cause leakage.
Common mistakes
- Installing a sprinkler that was dropped, struck or slipped by the wrench. The datasheet requires any such sprinkler to be replaced.
- Painting or coating sprinklers on site. Sprinklers must not be altered after leaving the factory; altered sprinklers are replaced.
- Hanging objects from sprinklers, or cleaning them with anything other than a gentle feather duster.
Maintenance
Sprinklers that leak or show visible corrosion must be replaced, as must sprinklers exposed to corrosive products of combustion that cannot be fully cleaned. The owner is responsible for inspection, testing and maintenance to NFPA 25 and the authority having jurisdiction, preferably by a qualified inspection service. Before closing a main control valve for maintenance, obtain permission from the proper authorities and notify everyone affected.

FAQ
What does TY5130 mean?
It is TYCO’s Sprinkler Identification Number (SIN). It identifies the exact model — orientation, K-factor and thread. The sprinkler is ordered by this number together with temperature rating and finish.
How do I choose the temperature rating?
From the highest expected ceiling temperature and the rating classes in the project’s governing standard, within the ratings available for this model in the datasheet.
Do all models in the series carry the same approvals?
Not always. The approvals table in datasheet TFP345 gives each model’s approvals by rating and finish, so check it when the project requires a specific approval.
What is the benefit of quick response?
The thermal element reacts faster, so the sprinkler operates earlier and limits heat and smoke spread; standards require it in some occupancies such as light hazard.
