![]() Power Input (Operating Voltage): 8-32 VAC, 8-40 VDC.A flashing LED indicates the cause of shutdown identified by the nameplate Provides 8-point first out cause of shutdown Tattletale.Selectable sensor lockout for delay on startup.Includes SPDT dry contact output rated 2 A 28 VDC.At the same time an output circuit is activated which allows you to connect an external relay to operate a general alarm, operate a shutdown device, etc. When an alarm sensor trips, the LED flashes and, if equipped, the MINI-SIREN® sounds. Preprinted peel and stick nameplates for common faults are supplied with each unit. Applications include process monitoring such as compressors, pumps, generators, etc. The fault is annunciated and locked in until reset by the operator. Preprinted peel and stick nameplates for common faults are supplied with each unit.įirst out fault Tattletale tells you which monitored variable malfunctioned first. Alarm Silence/Test button allows you to test all LEDs. The flashing LED remains in operation until the fault is corrected and the contacts reset. Depressing the Alarm Silent button silences the local audible alarm and disconnects the output for the remote alarm. At the same time an output signal is generated which allows an external relay to be wired to operate a general alarm such as a bell or horn. When a fault occurs, the contact operation causes the appropriate LED to flash and the audible MINI-SIREN to pulse. Other applications include power plant control rooms or building maintenance, for remote drilling rigs, construction sites, agricultural and construction equipment. Each repeater panel can be acknowledged individually or alternate wiring allows for one master control to silence all repeater panels. Repeater panels can be added for additional locations such as flybridge, on deck, galley or engineer’s quarters. Typical applications are in marine pilot houses to alert the crew of problems developing in engine, gear, bilge, auxiliary power plants, etc. This ST8-LM used wherever a remote alarm and annunciation is required. This “first out” feature means that only the first fault will be shown by LED this feature isolates the primary cause of shutdown, and helps simplify troubleshooting. The Murphy Selectronic Tattletale Annunciator with 8 First Out Visual ST8-LM is an eight point Tattletale panel designed to give “first out” indication of cause of alarm or shutdown.
