What pressure does the oil safety switch cut off?

The oil safety switch is designed to monitor the pressure of the oil system in a fire alarm system or related equipment. The primary function of this switch is to ensure that the oil pressure remains within safe operating limits. When the oil pressure drops below a certain threshold, which is between 9 and 10 PSI, the oil safety switch will activate and cut off the system to prevent potential damage and ensure safety.

This pressure range is critical because it indicates that the oil is no longer circulating properly, which could lead to overheating and equipment failure. Maintaining pressure levels within this range helps ensure that the system continues to operate efficiently and safely, mitigating the risk of fire hazards associated with inadequate lubrication in machinery.
