2AFH5TXR1Water protection system

______________________________________________________________________________________________________ Page 1 of 7 WaterStopper User Instruction Setup and Troubleshooting guide Thank you for purchasing the newest, most exciting development in home automation. WatersStopper is an affordable state of the art, purpose designed and built system that allows the user to easily reduce their risk of water damage caused by burst or leaky pipes inside a building. All water systems leak, it is just a matter of time. System description Water damage from burst or leaking pipes presents a major risk to landlords and home and business owners. Such losses add up to billions annually. While many such losses may be insurable, the inconvenience and stress associated with such disasters is stressful and unnecessary. The WaterStopper system consists of 5 water sensors which, when activated(by water), send a coded signal to the receiver. The receiver actuates a ball valve (included) which is installed in- line with the building’s main water line. This closes the valve and minimizes any further water damage. The receiver’s LED turns from green to red and the receiver emits an audible alarm tone. The receiver also sends a text (via Ethernet) if it has been plugged into a connected router with an Ethernet cable. This alerts the user of the water situation and allows them to take timely action. Precautions and limitations There are some important things to remember when setting up and using your new system 1) Like all low power radio devices it has a limited range. The sensors should not be located more than about 60 feet from the receiver. 2) A repeater unit can be installed between the sensor and the receiver to help increase the range. 3) The repeater is powered using a 3.3V DC adaptor (wall wart) with a smaller barrel jack. 4) The receiver is powered using a 5VDC AC adaptor (wall wart). It can also be powered using USB to barrel jack (cable supplied). If the receiver is not powered (indicated by a green LED) , the system will not function. 5) The ball valve must be installed correctly as described and illustrated below. The electrical cable must be plugged fully into the side of the receiver in order to actuate the ball valve and to allow the ball valve to be reset following a repair of a leak. ______________________________________________________________________________________________________ Page 2 of 7 Figure 1- Sensor Top side- coins for size comparison 6) Placement of sensors is important. The local microenvironment may require that the sensor is moved a few inches to allow its transmission to be received. 7) Sensors need to be located near a source of potential leaks, such as between a sink and a toilet, beside a hot water heater or near the floor drain in a basement. 8) Use of any unapproved parts or using the supplied parts in ways not described here could lead to unsatisfactory performance and loss of protection against water damage Figure 2- Electrical ball valve- prior to installation ______________________________________________________________________________________________________ Page 3 of 7 Regulatory warnings FCC/Industry Canada  This device complies with FCC Part 15 and Industry Canada license exempt RSS standard(s).

Michael Cogill- Owner [email protected] 403-462-1857 August 27, 2015 Nemko Canada Inc 303 River Road Ottawa K1V 1H2 Canada Differences between “sensor” and “repeater” models The sensor (figure 1 below) is a simple compact water sensor circuit that automatically turns on a radio transmitter (nRF24L01+) and sends a coded signal over a discrete frequency (2468 MHz) on the ISM band, when the contacts get wet. It is battery powered by 2x 2032 primary lithium batteries and is only on when the sensor is wet. Figure 1-Schematic drawing of Sensor Michael Cogill- Owner [email protected] 403-462-1857 The repeater (figure 2 below) is a simpler version of the exact same parts as the sensor. The two circuits have identical RF performance and RF components. The Repeater is a simpler (fewer parts- no switching or power regulation) version of the sensor. It is powered by an AC adaptor and remains in receive mode until it detects a transmission from a sensor. The device then switches to transmit mode to transmit an equivalent sensor signal to the receiver. The repeater demodulates the received signal and re-modulates the signal that it sends out. It does not remain in the send mode but returns to receive mode after a brief time period.

Operational description The device is a simple compact water sensor circuit that automatically turns on a radio transmitter (nRF24L01+) and sends a coded signal over a discrete frequency (2468 MHz) on the ISM band, when the contacts get wet. This allows a receiver to close the water main valve (there is an electrically actuated ball valve installed in series with the building’s manual shutoff valve), emit an audible tone, light a visual indicator and send a text message to the user. The receiver has a reset button that is depressed which allows the valve to be reopened and the system returns to its ready state. The device can also be programmed to act as a radio signal repeater for a nearby sensor. In that case, it is a simpler (fewer parts- no switching or power regulation) version of the sensor. It remains in receive mode until it detects a transmission from a sensor. The device then switches to transmit mode to transmit an equivalent sensor signal to the receiver. The repeater demodulates the received signal and re-modulates the signal that it sends out. It does not remain in the send mode but returns to receive mode after a brief time period.
