Overview

The EnviroAlert® EA800 Multi-Zone Environmental Alarm System monitors the environmental conditions detected by the sensors connected to the base unit, and provides alarm signals when monitored conditions at any of the sensors exceed the user-programmable HIGH LIMIT or LOW LIMIT set points. The alarm signals are provided via relay outputs that can operate with process controls, security systems, or other similar automated equipment. The EA800 Alarm System can be configured with wired or optional wireless sensors (sold separately). The EA800 allows connection of up to 4 wired and 4 wireless sensors.

Setup and programming is done using the front panel keys and the liquid crystal display (LCD) on the base unit. The display assists the user during setup, and shows measured conditions for the monitored environment during operation.

The EA800 can monitor multiple critical environments using multiple sensor inputs. Each sensor input/alarm channel is designated a “Relay”.

Using the appropriate accessory sensors (sold separately), the EA800 Alarm System monitors and provides alarms for the following conditions:

■Normally open/normally closed contacts

■Temperature: from -80° C to 150° C (-112° F to 302° F)

■Humidity: from 5% to 95% RH (non-condensing)

■Presence of water

■Any sensor with a 4-20mA interface

The EA800 base unit may be mounted directly to a 3-gang electrical enclosure or to walls. The wireless sensors are easily mounted to the wall. Figure 1 shows the base unit and a wireless sensor.
