Set-up the LoRaWAN Gateways
Prior to installation of your Noah sensors, Kairos should have visited and installed the radio network of LoRaWAN gateways. These gateways should already be listed and online in your account at portal.kairoswater.io.
If you find that the gateways are not showing in the Gateway section of the portal, please reach out to support@kairoswater.io requesting a status on those gateways.
Set-up the Noah Multifunction Leak Sensor
- Each module should arrive and already be added to your account in portal.kairoswater.io. If you find that is not the case, please reach out to us at support@kairoswater.io with the devEUI you need added.
- Turn on the Noah following the instructions in Operation section of this manual.
- Check portal.kairoswater.io to see if the module is showing as online now. When you log in to the portal, there is a "Lookup Device" feature in the upper left. Click on that and scan the QR code on the bottom of the device, or else type the characters in manually and click search. The device should be found. If you encounter any errors in searching, please reach out to us at support@kairoswater.io.
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
- 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.
- 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.
- 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.
- There is a protective film covering the black conductive traces. THIS PLASTIC FILM MUST BE REMOVED BEFORE INSTALLATION. Simply peel it away from the heavier plastic and traces.
- Connect the membranes to the wireless modules using the supplied cable.
- If the cable is not already attached to the membrane,
- Slide one of the tabs sticking out from the membrane into the slot of the ribbon connector making sure the dull black strips are touching the silver contacts in the white connector.
- Clamp the cover over the tab so that the dull black contacts on the membrane touch the contacts inside the ribbon connector.
- Insert the small plug into one of the wireless module's ports.
- Slide one of the tabs sticking out from the membrane into the slot of the ribbon connector making sure the dull black strips are touching the silver contacts in the white connector.
- 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 and retained using the provided wire clips, or in a space under or next to the appliance. Additionally, the small strip of gaffer's tape can be used to hold the membrane connector to the floor.
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 – as depicted below. The remaining halves can be connected to separate wireless modules or two ports on one wireless module.
20”x20” 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 – as depicted below. The remaining halves can be connected to separate wireless modules or two ports on one wireless module.
20”x30” Format
This format is recommended for refrigerators and the largest areas. Once again, this format can be shortened by cutting it along the horizontal – as depicted below. The remaining halves can be connected to separate wireless modules or two ports on one wireless module.
6”x30” Format
This format is designed to fit under most PTAC 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.
1”x12” (Tee) Format
This format is recommended for tight spaces and around the base of toilets or inside overflow/condensation pans.
As an example, below is a tee membrane installed on the back of a toilet base where anode (a) and cathode (b) must be bridged by a leak on the floor that surrounds the toilet.
Tape (Reel) Format
This format is recommended for outlining an area which could, but should not, experience a flood of water. Examples include elevator service pits, pump rooms, chiller/boiler systems, etc.
The tape has notches indicating every one foot of tape that is rolled out from the reel that it come rolled in.
Below is an example of tape adhered to the floor of an elevator shaft service pit in order to catch any leaks from units above that would pour into the pit.
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.
Operating NOAH
Powering on/off & Resetting
Turn on: All devices are shipped in the “off” state. Press and hold button underneath the unit for 3 seconds until the RGB indicator flashes once and the unit emits a chirping sound - release the button to turn on device. You will feel a faint “click” when the button has been engaged.
Turn off: Press and hold button for 8 seconds until the green LED indicator flashes quickly; then, release the button. The green indicator will flash 20 times to show that the device is turning off and the device will emit a short chirping sound.
Notes
- When the battery is removed and reinserted, NOAH defaults to the “off” state.
- Powering NOAH off restores the factory defaults.
Joining a Network
NOAH is designed to automatically check for gateways within range. In order to verify the device has found a gateway:
- Make sure NOAH is turned on.
- When it has located a gateway the green LED will stay on for five (5) seconds to show it has access to the network: otherwise, the green LED will continue to flash as the device listens for a response from the network.
- If the NOAH’s search for a network times out, the red LED will turn on for five (5) seconds,
- NOAH try to join a network again in fifteen (15) minutes.
Button Functions
Pressing the button once will wake the device, which will then send a report to the portal.kairoswater.io.
Press and hold button for eight (8) seconds to reset and restore factory settings. The green LED will flash quickly twenty (20) times to indicate the reset was successful. This action also turns the device off; it will need to be turned on again.
Reporting Frequency
While turned on, NOAH sends a message to portal.kairoswater.io every fifteen (15) minutes, by default and can be adjusted on later models of Noah.
The only exception is when the device detects an abnormal reading, it will immediately send a report to portal.kairoswater.io. Abnormal readings are when:
- A leak is detected (water is present on the leak detection membrane)
- The device is bumped or moved triggering a tamper alert
- The temperature rises above 110°F
Note: Custom alerts can be created for your devices by coordinating with the Kairos team and reaching out to support@kairoswater.io.
Restore to Factory Setting
NOAH saves certain information; including network security and configuration settings. To restore factory settings:
- Press and hold button for 8 seconds until the green LED flashes; then, you should release the button. The green LED will flash quickly 20 times to indicate NOAH has successfully reset.
NOTE: NOAH will be “off” after a factory reset; and must be turned on again to resume normal operation.
Sleep Mode
NOAH is designed to be power efficient and will enter a sleep mode during operation.
- While the device is in the network, it will sleep for fifteen (15) minutes before checking back in with the network. Abnormal sensor readings will awaken NOAH, in which case it will send a report, chirp and flash the LED.
- If NOAH is not in the network or it cannot receive messages from the network, it will enter sleep mode and wake up wake up every 15 minutes to check it the network is available.
