EnviroAlert EA200
Figure 2 shows a simplified functional diagram of the EA200 interfaces and functions.
The EA200 provides two Zones of monitoring as follows:
„ Zone 1 – Zone 1 is permanently programmed as a temperature monitor using a
temperature sensor built-in to the EA200.
„ Zone 2 – Zone 2 is equipped with a sensor input connector that can be connected to
any one of a variety of sensors. Using the appropriate sensor, Zone 2 can be used
to monitor temperature, humidity, or presence of water at remote locations.
Each Zone has its own Form C relay output that activates when a monitored
environmental condition exceeds the programmed range. An AUX (Auxiliary) Output
relay is activated whenever any Zone is in alarm. It can be used to provide a single
output to the alarm panel or to an optional audible alarm.
