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.
