Block Diagrams
Figure 2 shows a block diagram of the base unit interfaces and functions. The EA800 provides eight relays for
indicating when a programmed alarm limit has been exceeded or a warning condition exists. An additional AUX
(Auxiliary) Output relay provides an output signal to an optional audible alarm or strobe that is activated whenever
an alarm condition exists.
Figure 2 EA800 Environmental Alarm System Block Diagram
The EA800 can be made part of a larger security system as shown in Figure 3. In a security system there may be
more than one EA800 installed along with other components such as the Winland EA200 or EA400 multi-zone
environmental alarm systems.
