EO 1.1.5 Describe the operation of the Halon system to include the function and interaction of the system components and the interface with other systems 1.1.5.1 Main Idea <OB 70153(1114)><< Describe the operation of the Halon system to include the function and interaction of the system components and the interface with other systems as well as any applicable industry events. Operations Halon stored at 600 psig, providing chemical distribution using N2 propellant No "odorizer" due to Halon's non-toxicity at low concentrations Inverter/Communication/Computer Rooms C) Refer to M658-00001 Manual discharge By pulling lock pin on top of cylinder a) Palm button presses pin into pneumatic actuator, then pressing red schraeder valve releasing the palm button pressure from the upper valve chamber Discharge (ported from valve body) actuates pressure switch Pressure switch sends signal to control panel for damper actuation, door closures Automatic Discharge a) Two zones per Ansul panel; Cross-zoned (2 of 2) ionization One detector from each zone
