Abstract
A fluid status detection system includes a controller that has eight sets of sockets for mechanically receiving a solid state input module. The module may be either an one of two A.C. responsive moduled responsive to two different A.C. voltage ranges or a D.C. responsive module. Either module provides the same output, a one-bit-digital signal, to the controller via the sockets. The controller includes a relay, an alarm, and a display. The operator may select one or more indicator conditions individually for each of the socket sets from a plurality of possible indicator alarm conditions and store the conditions in the controller. The controller then responds to the one-bit-digital signals to provide an alarm or other programmed indication that a device, such as a fire alarm, connected to a particular socket set has been activated. The modules respond to a wide range of voltages, thus a wide range of devices may be connected to the controller.
