Overview
The ALERT200X is the next-generation ALERT and ALERT2 transmitter designed to deliver reliable, real-time hydrologic and meteorologic data for critical flood warning applications. At its core, the AL200X ALERT and ALERT2 Modem and Sensor Interface operates in field station mode, providing advanced functionality through a familiar and easy-to-use interface. With expanded sensor inputs and outputs, the ALERT200X provides the versatility required for most remote stations while delivering a powerful and cost-effective solution for modern flood warning networks.
The transmitter can be configured for ALERT or ALERT2, giving you the flexibility to meet today’s requirements and prepare for future upgrades. Transitioning from ALERT to ALERT2 is simple; just update the configuration without replacing any hardware. With the canister, enclosure, and panel options, the ALERT200X easily adapts to your installation needs—even if you deploy new stations or upgrade existing ones.
Whether you manage a single watershed or a regional network, the ALERT200X gives you the confidence to make timely, informed decisions. Protect lives, safeguard property, and enhance resilience with the transmitter built to perform when it matters most.
Note: ALERT2 is a trademark of the National Hydrologic Warning Council.
Note: The main image displays the canister, enclosure, and panel options collectively. Each option is sold separately.
Key Advantages
Fully configurable transmitter for ALERT and ALERT2 systems
Technical Description
The ALERT200X is built around an AL200X ALERT and ALERT2 Modem and Sensor Interface and the industry-standard Maxon VHF radio. It includes integrated GPS from the AL200X for accurate, real-time clock synchronization.
Note: A GPS antenna is required for ALERT2 applications and is highly recommended for ALERT.
The ALERT200X is available in three different package options to meet your needs:
- The canister option includes six standard, M12, eight-pin, circular connectors for sensor I/O, as well as coaxial connectors for GPS and VHF radio. You can easily connect existing sensors at your field station using the available M12, field-wirable connector kits.
- The enclosure option is built around the same platform as the canister option, but it is housed in a fiberglass enclosure with cable glands and internal DIN rail terminals for connecting external sensors.
- The panel option is designed for applications where an enclosure will be provided separately. It carries the same design as the enclosure panel with DIN rail terminals for easy sensor connections.
All three options are configured, deployed, and maintained via the intuitive AL200X user interface using Campbell Scientific's Device Configuration Utility (DevConfig).
Benefits
- Canister, enclosure, or panel configuration to fit any flood warning station
- Modular mounting of components for more convenient field servicing and expansion
- Updated M12 canister connector for easier connection of new and existing sensors
- Additional sensor or external communications cable routing with two spare, sealed cable-entry glands on the canister
- Power any site with up to a 24 Ah battery, supported in all configurations
- Reduced setup time and simplified maintenance with an intuitive user interface
