fire sprinkler part or sprinkler fittings The bulb breaks as a result of the thermal expansion of the liquid inside the bulb. The time it takes before a bulb breaks is dependent on the temperature. Below the design temperature, it does not break, and above the design temperature, it takes less time for higher temperatures. The response time is expressed as a response time index (RTI), which typically has values between *5 and **0 m½s½, where a low value indicates a fast response. Under standard testing procedures (**5 °C air at a velocity of 2.5 m/s), a *8 °C sprinkler bulb will break within 7 to *3 seconds, depending on the RTI. The RTI can also be specified in imperial units, where 1 ft½s½ is equivalent to 0.*5 m½s½. Of course, if a ceiling has been painted, and some paint gets on a bulb, it will not operate as it should.
