Meraki MT12 Cloud-Managed Indoor Water Leak Detection Sensor

Protect mission-critical IT infrastructure with the Meraki MT12 water leak detection sensor. This cloud-managed device is purpose-built to detect even small leaks before they become costly outages, delivering rapid alerts, centralized visibility, and automatic response options through the Meraki ecosystem. Designed for indoor environments such as data centers, server rooms, network closets, and optical huts, the MT12 provides proactive protection against water intrusion, helping you minimize downtime, extend equipment life, and keep your operations running smoothly.

• Cloud-first monitoring and alerts: The MT12 connects to the Meraki Cloud, giving you real-time leak monitoring from a single, centralized dashboard. You get immediate push notifications, email alerts, and detailed event logs that let IT teams respond quickly, correlate incidents across sites, and maintain a comprehensive view of environmental health. This cloud-based approach simplifies management for distributed environments and scales with your growing network footprint.
• Ultra-sensitive water detection: Engineered to detect trace amounts of liquid, the MT12 provides early warning of water exposure—well before it affects critical equipment. Its sensitive sensing capability helps you intervene fast, reducing the risk of outages, corrosion, and collateral damage to racks, cables, and power systems. Early detection translates into faster containment and lower repair costs.
• Easy deployment and scalable coverage: The MT12 features a compact indoor form factor and flexible mounting options, allowing you to position sensors precisely where leaks are most likely to occur—around pipework, behind racks, under cooling units, or near under-floor plenums. Its scalable design makes it simple to expand coverage as your data center or network closet footprint grows, without complicated wiring or costly installations.
• Automated actions and integration: In addition to alerts, the MT12 supports Meraki automation and policy-driven workflows. This enables you to trigger connected responses or escalation procedures automatically—such as notifying on-call personnel, initiating cooling adjustments, or integrating with other management systems—so you can contain leaks and minimize disruption with minimal manual intervention.
• Reliability and secure operation: Built for enterprise reliability, the MT12 offers secure cloud communication, robust battery-powered operation, and a design that supports long intervals between maintenance. It provides proven performance in demanding environments, giving IT teams confidence that leak monitoring remains active around the clock, even when staff are not onsite.

How to install Meraki MT12

• Plan the sensor placement in high-risk indoor areas where leaks are most likely to occur—around pipe connections, under cooling equipment, near dry-vented basements, and at entry points to IT rooms.
• Unpack the MT12 and verify all mounting components are present. Choose a mounting surface that is stable and accessible for maintenance checks and sensor cable placement.
• Mount the MT12 securely using the provided hardware. Ensure the sensing area is unobstructed and that any sensing cables or pads are positioned to maximize contact with potential liquid exposure.
• Power the device according to the manufacturer’s guidelines and connect it to your Meraki network. Access the Meraki Dashboard to begin the setup workflow, assign the MT12 to the appropriate network, and verify connectivity.
• Configure alert preferences, thresholds, and automation rules in the dashboard. Set notification channels (push, email, or SMS as supported by your license) and determine escalation paths for critical leaks.
• Test the installation by simulating a small amount of water near the sensing surface. Confirm that the MT12 detects the leak and that alerts propagate through the Meraki Dashboard and configured channels. Review logs after the test to validate detection timing and response actions.
• Document the sensor locations and maintenance schedule. Schedule regular checks to ensure sensors remain clean, unobstructed, and properly calibrated for ongoing accuracy.
