XW-112™ Wi-Fi Water Detector Users Manual
Installation and Setup
2.4 Application Example
Remote Alarm Example
You wish to receive an email alert and activate a buzzer or light to indicate that a water leak has
occurred. The sensor is within range of a Wi-Fi access point and AC power is available.
Install a WebRelay™ or WebSwitch™ in your office and connect it to your Ethernet network. Connect a
buzzer or light to the relay contact. The WebRelay must be accessible from the Wi-Fi network and be
assigned a static IP address. Your Wi-Fi network must have adequate coverage to connect to the XW-
112 as well. Connect the GRI-2605 sensor to the XW-112 and mount it near the floor where the water is
to be detected. To provide for an AC power-fail email alarm, install two AA batteries.
(
Note:
Your Wi-Fi
access point must be powered by an uninterruptible power supply (UPS) in order to send a power-failure
notification.)
First, the XW-112 must be configured to access your Wi-Fi network. If no network profiles have been
configured, the XW-112 will automatically enter access point mode and you can access the XW-112
directly with a computer or mobile device with a wireless connection. If the XW-112 has been previously
configured for other uses, press the Access Point button. Scan for, and attach to the XW112-XXXXXX
wireless network. Access the setup pages with the following URL: http://192.168.1.2/setup.html
Configure the XW-112 to connect to your wireless network. Navigate to the WiFi Networks tab and fill in
the appropriate settings for your Wi-Fi network. Obtain an available IP address from your network
administrator. Press the Submit button at the bottom of the page. (The XW-112's internal web server is
always enabled and accessible.)
Navigate to the
Water Sensor
tab. On the
Email Alerts
setting, select
On
. Change the
Description
text to
a descriptive name such as “
Laundry Room Water Sensor.
” This text may be up to 40 characters long
and appears on the
Control Page
and in email messages when email alerts are enabled. Click the
Submit button at the bottom of the page.
Navigate to the
tab and enter the SMTP server settings as well as the username and password (if
required). You may need to contact your email provider for the exact settings to use. To provide ongoing
assurance the XW-112 is working, enable the
Weekly Status Email
option.
Set the
Remote Relay Options
to
Remote Command Opposite of Sensor
. With this setting the remote
WebRelay or WebSwitch's relay will be On when the water sensor detects water, and Off when the
sensor is dry. This setting is needed since the water sensor is a supervised closed-loop alarm circuit.
Upon selecting an action, the remote relay options will show, and ask you to specify the WeRelay or
WebSwitch's IP address, port, relay number, etc. Enter these settings for the WebRelay/WebSwitch and
press the Submit button at the bottom of the page.
Once all the appropriate settings have been applied, click on the
Reboot
button on the Main tab, the
XW-112 will then reboot and begin operation. The XW-112 will no longer broadcast an SSID. The web
page will now be available at the assigned IP address. If a water alarm is detected, an email will be sent
and the remote relay will be activated. You will receive a weekly email which indicates the XW-112 is
connected and working (if selected in the Email tab).
