Frank W. Murphy Tattletale® Annunciators and Magnetic Switch

• The nerve centers that translate Swichgage contact operations into decisions and operate the alarm or shutdown device. • They are the electrical load carrying devices for the alarm or shutdown device. • Tattletale annunciators indicate which monitored function failed leading to the alarm or shutdown whereas magnetic switches do not. • Magnetic switches operate basically as a latching relay. MODEL 518APH • Allows for Swichgage and/or N.C. contacts to be wired “Closed Loop”. • Any contact open or Swichgage contact close in the circuit shunt trips the 518APH. MODEL 760A/761APH - RESETS AUTOMATICALLY • Use for distributor ignition or diesel. • Time delay lockout of Swichgage contacts on start-up only; customer wired for delayed or immediate trip on shutdown. • Breaks and makes circuits when tripped. • Time deplay: 30 seconds. MODEL 117 - MANUAL NON-INDICATING • Use to shutdown 12 volt thru 32 volt distributor ignition or diesel engines. • Breaks circuit when tripped. • Opens distributor coil circuit or power circuit to diesel run device. • Automatically disconnects from battery after trip. • No time deplay MODEL MS2100 - MANUAL INDICATING • Multi purpose Tattletale with dry contacts that can be used to make two circuits and break another when tripped. • Operates from 120 VAC or Capacitor Discharge Ignition. • The operating coil is intermittent duty and must be disconnected by an external circuit when tripped. • No time deplay
