this is from a document from an engineering firm
"Elevator shutdown, frequently referred to as shunt trip, is intended to immediately stop elevators before water from elevator machine room or hoistway sprinklers affects brakes and electrical equipment. Both wet brakes and wet electrical equipment can cause erratic life threatening elevator operation. Therefore, it is required by Requirement 2.8.2.3.2 of A17.1 to cause disconnection of the main line power supply upon or prior to the application of water from sprinklers in the machine room or hoistway. This occurs even if the elevator car is occupied and not at a landing. Pit sprinklers located less than 2 feet above the pit floor are exempt from this requirement because Requirement 2.8.2.3.4 of ASME A17.1 requires all electrical equipment within 4 ft of the pit floor to be NEMA 4 rated. Therefore, heat detectors or waterflow switches will typically not be required for shunt trip involving pit sprinklers. "
