Essential Info

The EnviroAlert® EA400-12 provides alarm signals when monitored conditions exceed the user-programmable HIGH LIMIT or LOW LIMIT set points. The alarm signals are provided via relay outputs that can operate with alarm panels, process controls, security systems, or other similar automated equipment. All setup is done using the front panel keys and the LCD display, which uses icons that indicate the setup and parameter being configured. The LCD display assists the user during setup, and shows measured conditions for the monitored critical environment. The EA400 can monitor multiple critical environments using multiple sensor inputs, with each sensor input/alarm channel designated as a "Zone."
