Have you ever walked into a Pre-Action Sprinkler System or Deluge Valve Sprinkler room and observed the “actuator” hanging loosely by, not connected to its proper valve actuator? This is a serious impairment of the system, as it will NOT operate upon detection as intended. Fear not, the NFPA 13 Technical Committee recognized that this is an important issue and resolved it with the requirement to monitor the actuator to ensure it is in place as required and the system will operate as intended if called upon.
NFPA 13 2019 8.3.1.2.1 Actuator Supervision. Effective January 1, 2021 removal of an electric actuator from the preaction or deluge valve that it controls shall result in an audible and visual indication of system impairment at the system releasing control panel.
