BATTERY POWERED, RADIO INTERFACED, WATER LEAK DETECTION SENSOR FOR FLATS AND HOUSES

To add to our range of water detection alarms, CMR Electrical have developed a battery powered water leak sensor that can operate as a stand alone unit or communicate to a remote alarm unit, wire free, using radio signals. For easy of locating the leak, the sensor has its own built in “Battery Low” or “Water Detected” audible warning, or can send both alarms to a remote alarm unit via its own 868MHz signal. Between one and four remote sensors can be connected to an alarm unit, providing wire free water leak detection sensing in areas such as kitchen, bathroom, shower room basement or areas that running cables too would be difficult. Providing no more than four sensors are installed, additional sensors can be added at anytime. Being powered by two “AA” batteries and wire free, each sensor is provided with a hook & loop (Velcro) tape allowing it to be easily fitted to a wall, tiles, skirting, behind a toilet, under a sink etc. The sensor is also provided with a one metre length of water sensing cable that can be cut using a pair of scissors to any length to suite the environment i.e., behind a toilet could be a 15cm long detection cable, whilst under a bath or sink 100cm cable might be best. To extend the life of the batteries, the sensor checks for a water leak every 20 seconds before going back to sleep and automatically resets once the sensor cable is dry. To stop the sensor wire from eroding away due to electrolysis, the electrical detection signal is an alternating (AC) voltage. The remote alarm unit can monitor up to four remote sensors for “Low Battery”, “Not working” or “Water Detected” and if required, turn the water supply off if a leak is detected. The main screen on the alarm unit displays the common status of all fitted sensors advising if one of the sensors needs a battery change and or if a sensor has detected a leak. Further information about the status of each sensor can be displayed by using the touch screen buttons. The alarm unit also has the ability to manually turn off the water supply in an emergency, or turn the water back on after a leak has been detected. If required, the alarm unit can be provided with a mutable sounder beacon and or text messaging unit.
