How do you test sprinkler systems?
The inspector’s test is typically located at the farthest point of the sprinkler system. The inspector will then open the inspector’s test, the inspector’s test simulates a sprinkler activating and shall send a signal to the fire alarm panel within 90 seconds.
How do fusible link sprinkler heads work?
A fusible link sprinkler head has a two-part metal element that is fused by a heat-sensitive alloy. Once the ambient temperature around the sprinkler head reaches a specified temperature, the alloy releases and the metal elements separate, which causes the pip cap to fall away.
How often should sprinkler systems be serviced?
Every 10 Years. Dry sprinkler systems should be tested and/or replaced after ten years. Fast-response sprinklers should be tested after 20 years and at 10-year intervals after that, and standard sprinklers should be tested after 50 years and then at subsequent 10-year intervals.
What sets off the fusible link in a sprinkler head?
Heat-Sensitive Elements A fusible link fire sprinkler head has two metal plates fused together by solder. The solder acts as the heat-sensitive element of a fusible link sprinkler. When it reaches its’ designated temperature, it melts, and the two metal plates detach from each other.
How is the temperature of a sprinkler system determined?
So, if it is routinely exposed to ambient temperatures higher than 100° F, it is liable to separate and trigger water flow. In most cases, a sprinkler’s temperature rating is stamped on the fusible link or stamped or cast on a visible part of a glass bulb sprinkler’s head.
Which is the best company to test sprinkler heads?

How is sprinkler testing carried out in Australia?
All of our Sprinkler Testing is carried out according to the high standards of the FPA Code of Practice, as well as the rigorous requirements of the relevant Sprinkler Testing codes. We also manufacture and supply quality Glass Bulb Fusible Links.
How does a fusible link fire sprinkler system work?
Fusible link fire sprinklers are held closed by solder with a predetermined melting point. An exception to these two triggers is found in a deluge sprinkler system, most commonly used to protect highly flammable or hazardous areas where fire can quickly burn out of control.
How does a Capitol fire sprinkler test work?
The test is completed by applying hydrostatic pressure to the fire department connection and maintaining the pressure for up to 2 hours. It must be conducted by a licensed fire sprinkler contractor, such as Capitol Fire Sprinkler in the presence of the Fire Department.
Where to find model number of central fire sprinkler system?
Central’s sprinkler (pictured left) lists the model “ELOC” on the bottom-left, but it’s difficult to tell at a glance which combination of letters refers to the exact model. Searching by the manufacturer or model number may turn up some documentation, such as an update to a manufacturer’s catalog.
What should I look for in a fire sprinkler system?
The stockier, elliptical bulb on the right is typical of a standard-response fire sprinkler. The quick-response model on the left features a leaner, cylindrical bulb. If the temperature rating isn’t listed on the fire sprinkler’s deflector, look for a glass bulb – the color of the liquid provides an indication of the activation temperature.
How does Dyne test a fire sprinkler system?
Dyne tests the response time of the sprinklers to ensure the sprinklers will release in a specified amount of time when exposed to a defined temperature and air flow. The acceptable response time is based on a response time index (RTI).
