What are they? They work by releasing water. Youtube channel, ScienceWorld shows the varieties of fire sprinklers and what they can accomplish.

Fire sprinkler companies can install different types of sprinklers. Each sprinkler comes with a tiny glass bulb, which is able to expand or break in the event that the temperature is excessively high. An orange bulb, for example, can trigger the sprinkler when it’s at the temperature of 57 degrees Celsius (135° Fahrenheit). A black bulb will only be broken at a high temperature of 227 degrees Celsius which is 440 degrees Fahrenheit. The colour of the bulb will determine the temperature at the point it’s going to explode.

Each of these sprinklers are connected to an overall system. Wet systems are the most popular. This method involves the filling of water pipes all the way to sprinklers. The system is intended to trigger individual sprinklers in order to limit the risk of water damage as well as false alarms.

Other kinds are dry system and preaction system. Dry, every pipe is filled by pressurized nitrogen gas instead of water. The likelihood of freezing is diminished by this. Preaction systems require two steps before activation. giyafot2c5.
