ALERT2 Bi-Directional Transmitter
Generous sensor capacity, local logging, and event and timed reporting — plus a bi-directional return path. From the office you can poll the station on demand, change its configuration remotely, and operate control outputs: gates, pumps, valves, warning signs. Commands over the return path are protected by the ALERT2 protocol's encryption and authentication — how bi-directional networks stay secure →

Ordering information
Specify the transmitter packaging and input configuration when you order — including when the transmitter ships inside a packaged 58xx station. Models carry the /A2 suffix for ALERT2; order the same option without /A2 for an ALERT (non-ALERT2) transmitter.

Where it's used
The 50388 is the platform inside every 58xx packaged station — rain 5854, level 5890, weather 5881 and water quality 5891 — and it's available alone for custom SCADA installations: gate and pump control, reservoir operations, and any site where the office needs to act, not just observe.
