The TYCO TY4332 is the horizontal sidewall model of the TY-FRB EC series, with a K 8.0 discharge coefficient and 3/4″ NPT thread, quick or standard response, per listing and installation and extended coverage, operated by a glass bulb 3 mm. It is designed for hydraulically calculated systems in light hazard occupancies such as churches, restaurant seating areas, hotels, educational facilities and offices, with coverage up to 16 × 24 ft (4.9 × 7.3 m). Installed along a wall or the side of a beam just below the ceiling, throwing water horizontally into the room. For where the sprinkler sits in the whole system, see the complete guide to sprinkler systems in Saudi Arabia.
In short
- Model (SIN): TY4332 — Horizontal Sidewall.
- Discharge coefficient K 8.0, 3/4″ NPT connection.
- Glass bulb 3 mm, quick or standard response, per listing and installation.
- Temperature ratings in the datasheet: 57 / 68 / 79 °C.
- Maximum working pressure: 175 psi (12.1 bar); 250 psi (17.2 bar) under UL.
- Series approvals: UL, C-UL, FM, NYC (per Table A). The approval of each model, finish and rating is in the approvals table of datasheet TFP296.
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 along a wall or the side of a beam just below the ceiling, throwing water horizontally into the room. The response rating of this sprinkler depends on coverage area and installation, per the datasheet table.
Models in the series
| SIN | Orientation | K-factor | Thread |
|---|---|---|---|
| TY3332 | Horizontal Sidewall | 5.6 | 1/2″ NPT |
| TY4332 — this model | Horizontal Sidewall | 8.0 | 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
- Minimum spacing is 10 ft (3 m), or 13 ft (4.0 m) when design pressure exceeds 175 psi. Minimum flow and pressure per coverage area are in the datasheet table.

The critical point: extended coverage has conditions
Extended coverage is valid only with the minimum flow and pressure given for each area in the datasheet, and in light hazard only.
Installation steps
- Inspect before installing: never install a sprinkler whose bulb is cracked or has lost liquid.
- Install the sprinkler in its correct orientation (Horizontal Sidewall) 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 6 (W-Type 7 for recessed)) within 10 – 20 lb-ft (13.4 – 26.8 N·m). Higher torque can distort the inlet and cause leakage.
- With an escutcheon, use only the specified one (Recessed: Style 10 / 20 / 30 / 40 as applicable) and never compensate for adjustment by changing the torque.
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 TY4332 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 TFP296 gives each model’s approvals by rating and finish, so check it when the project requires a specific approval.
