LCDT Selectronic® Tattletale®
The LCDT Selectronic Tattletale instrument is an electronic alarm/shutdown control system. It was designed
to protect engine-driven or motor-driven compressors and pumps. The
annunciator indicates the sensor, and hence the parameter, that
causes an alarm or shutdown. In addition, a means is provided for
testing the operation of each sensor without initiating an alarm or
shutdown. Employing a liquid crystal display, the LCDT system gives a digital
reading of the tripped sensor and the lockout timer countdown.
As the heart of the system, the basic annunciator component has two variations: the Model LCDT-NO, which accommodates normally open sensors, and the Model LCDT-NC, which accommodates normally closed sensors. The LCDT system accommodates 47 sensor inputs, 15 of which may be locked out during start-up by the start/run timer delay.

- Monitor engine or motor driven pumps and compressors
