Preparing the Hardware

Each N1 Leak Sensor is comprised of a:

• wireless module (1)
• membrane (1)
• cable (1)

Set-up your KAIROS Account

Either set-up a new account at app.kairoswater.io -or- follow the link you received in your email from info@kairoswater.io

1. If you are setting up a new account, you will add the devices manually following these instructions.
2. If KAIROS has already onboarded your devices, then you should see the devices in your account once you log into kairoswater.io from the link in your email.

Set-up the K1 Gateway

1. If the Gateway does not show on your app.kairoswater.io account, please follow these instructions to add it.
2. Identify a location where you have access to standard 110v (using the supplied adapter) or USB with 2A service. This location should also have access to Ethernet or password-protected WiFi. Otherwise, please send an email to info@kairoswater.io or chat with KAIROS at kairowater.io regarding a cellular modem for the gateway.
3. Connect the Gateway to the internet.
   1. Ethernet – simply plug the gateway into an active ethernet port using the supplied cable. Please check with your IT to ensure no firewalls are blocking access. If they require the MAC address, it is printed on the bottom of the gateway.
   2. WiFi – if WiFi is the best way to connect the gateway to the internet, please refer to this guide to set-up WiFi for your gateway. Or, you may contact KAIROS to send you a gateway provisioned for your WiFi network.
   3. Cellular – plug the ethernet cable into the gateway and the cellular modem. Make sure the cellular modem is powered on before going to the next step.
4. Plug the gateway to a power source. The power LED should illuminate. Over the next few minutes, the WiFi, Internet, and LoRa LEDs will illuminate as well. If the power LED turns red, but the rest of the LEDs remain green, there is no error and the gateway will perform as expected. This gateway in your app.kairoswater.io account will show as online now.

Set-up the N1 Wireless Module

5. If the wireless module does not show on your app.kairoswater.io account, please follow these instructions to add it.
6. Press the button on the side of the wireless module to send a message to the gateway.
7. Check app.kairoswater.io to see if the module is showing as online now.

Preparing the Installation Area

For the best sensitivity, the membranes should be installed over a flat surface, free of debris, deep gaps, or dirt/sand/dust. It is a good practice to sweep or vacuum the space onto which the membrane will be applied. In addition, for the “Tee” sensors and some water heater installations, it will be important to ensure the surfaces on which adhesive will be applied are cleaned before adhering the membrane to the surface.

Installing Membranes

1. Ensure that the membrane you are preparing to install is appropriately sized for the area it will be monitoring. There are a variety of membrane formats available for installation. Choosing the correct one for the area you want to monitor is important. More on membrane selection in the Installing Membranes section.
2. Membranes should cover the maximum area under the monitored space without bending or buckling. Ideally, the membrane should not stick out in highly trafficked areas where they would be stepped on or kicked out of position.
3. Some membranes come with extra tabs, if the cable is attached to one tab, and the other becomes unnecessary or interferes with the installation, you may cut it off so that the edge if flush with the bulk of the membrane.
4. Connect the membranes to the wireless modules using the supplied cable.
5. If the cable is not already attached to the membrane, simply (1) slide one of the tabs sticking out from the membrane into the slot of the ribbon connector and (2) clamp the cover over the tab so that the dull black contacts on the membrane make touch the contacts inside the ribbon connector. (3) Insert the small plug into one of the wireless module's ports.
   
   
6. In the spaces where the membranes will be slid under the thin gap for an appliance (dishwasher, refrigerator, washing machine, etc), the wireless module can be tucked under the cabinet overhang using the 3M adhesive on its bottom. Cords can be tucked underneath, or in a space under or next to the appliance.

 9”x18” Format

This format is recommended for Ice Machines and smaller coverage areas where the larger format will not fit. This format can be shortened by cutting it along the horizontal between the black traces an through a row of perforations leaving a connection tab for both halves – depicted below. The remaining halves can be connected to separate wireless modules or two ports on one wireless module.

20”20” Format

This format is recommended for Clothes and Dish Washing Machines. As with the 9”x18” membrane, this format can be shortened by cutting it along the horizontal between the black traces an through a row of perforations leaving a connection tab for both halves – depicted below. The remaining halves can be connected to separate wireless modules or two ports on one wireless module.

30”30” Format

This format is recommended for refrigerators and the largest areas. Once again, this format can be shortened by cutting it along the horizontal between the black traces an through a row of perforations leaving a connection tab for both halves – depicted below. The remaining halves can be connected to separate wireless modules or two ports on one wireless module.

Water Heater & PTAC (6”x30”) Format

This format is designed to fit under most PTAC (Portable Terminal Air Conditioning) units and wrap around water heaters when cut in half.

After cutting “bridges” 1 and 2, regions “A” and “B” can be monitored separately by connecting the leads from “a” and “b” connection bridges into separate wireless modules. In this way, the amount of fluid covering the membrane can be determined by the number of regions that are alarming. 

The design can be cut in half to create two 3”x30” membranes to wrap around opposing sides of a water heater . Each half should be connected to a wireless module.

Small adhesive tabs should be placed at the top corners of the membrane to keep the plastic attached to the side of the water heater. The connection tab and the plastic edge should touch the floor around the water heater.        

1”x12” (Tee) Format

This format is recommended for tight spaces and around the base of toilets or inside overflow/condensation pans.

Common Installation Areas

Tips

Installing the membrane upside-down - with the conductive side facing up - desensitizes the sensor to leaks. If the leak sensor is triggered by accidental exposure to small amounts of liquid (ice cubes falling on the floor and melting under the membrane), this orientation ensures that there must be a significant amount of water to trigger while avoiding the false alarms.
