Most industrial facilities are equipped with wet fire detection systems. The preference is hinged on the fact that water comes out of sprinklers the moment a fire alarm goes off. A wet system is different from a dry fire detection system because the piping and sprinkler systems contain pressurised air or nitrogen. Therefore, a dry fire detection system is efficient in as far as water consumption goes. This is attributed to a delay between a fire alarm going off and water being released from sprinklers.
