Water leak detection illustration featuring the ControlByWeb XW-112 Wireless monitor

Water leaks that go undetected can lead to major damage and equipment replacement costs. The XW-112 is a simple and effective way to detect potential leaks. With it, you can monitor for water leaks around water heaters and in server rooms, bathrooms, and areas near water tanks or pipes. The XW-112 is a self-contained device that doesn’t require any additional equipment or software to run—all you need is a local router to enable email notifications.

XW-112 Features

  • Built-In Web Server
  • Email Notifications
  • Alarm Control Through CBW Devices
  • AC Power Failure Notification*

*This feature requires AA batteries to be installed and backup power must also be provided to the local network that provides internet connectivity.

Equipment Monitoring

The above illustration shows how you could use the XW-112 to monitor for water leakage in a server room. In this example, the XW-112 is mounted in a dry area near the source of water, above the water pipes to ensure it remains dry in the event of a leak. The sensor is mounted on the ground where water would most likely accumulate.

Once mounted, the next step is to set up the XW-112 using its simple web-based dashboard. Connect to the local WiFi network and input all the information required for email notifications. Since the XW-112 isn’t dependent on cloud services or servers, it is necessary to input an email server name, login, password, etc.

XW-112 live demonstration setup

Live Demo With One of Our Sales Engineers

Let’s make it easy with a live demo and screen sharing.

Set up a one-on-one Q & A with one of our experts. We’ll help you find the best solutions for your next project and walk you through a demonstration.

XW-112 Setup

The diagram illustrates how this demonstration is wired. Nothing is connected to the relay contacts; however, you can still turn the relay on and off to see how it works. The input state only changes when a voltage is applied to the input. For this demonstration, we have connected one of our X-332 controllers to the input of the XW-112. You can apply a voltage to the input of the XW-112 by accessing the control page for the X-332 (Digital Input Control Page).

Important Information

  • Multiple users may be accessing this device simultaneously so the device can change while you are using it.
  • This unit will be reset to factory defaults daily at 2:30AM MST.
  • Please DO NOT change network or password settings.
