EN204-SG-12 Annunciator Tattletale (25700403)

EN204-SG-12: Four Function Annunciator Tattletale - Oil Pressure, Coolant Temp, Battery Voltage, Glow-Plug Energized; 12 Volts (25700403)

 

The Murphy Four-Function Tattletale Annunciator with Glow Plug LED Indicator EN204-SG-12 works with other engine components to clearly indicate critical engine operating conditions. The four bright LEDs on the face of the Annunciator indicate the cause of an alarm or shutdown condition. Model EN204-SG-12 substitutes the fuel level indicator with a glow plug indicator for those engines that use a glow plug for easier starting.

The EN204-SG-12 is used in conjunction with Murphy Electric Swichgage instrument or other normally open switches that close to ground when a fault condition occurs. As an example, in a system with a Murphy EGS21P-100 Oil Pressure Swichgage instrument, the Swichgage closes to ground when the oil pressure drops below a pre-determined set point. This will energize the Oil Pressure LED on the EN204 to highlight a low oil pressure failure. A very important feature of the EN204 is the ability to interface with Murphy 518PH or the 760A Electromagnetic Switches to perform automatic engine shutdown when fault conditions occur. The EN204 can also be used with other Murphy visual and audible alarms (STAS series remote alarm, SAH audible alarm, and the TL7 visual alarm) for remote annunciation and equipment shutdown.
