ONCWPRRange Enhancing Repeater

Owner’s Manual / Installation Guide www.watercop.com 800-545-3636 System Description The WaterCop ® PRO System is designed to detect leaks in your plumbing system at predetermined locations, and automatically shut off the water supply to help effectively reduce the chances of major water damage associated with a leak. System Components Brass Valve: Full Port, brass, 125psi cold water, designed for placement on incoming water main. WaterCop Actuator: NEMA 4 (weatherproof) Polycarbonate enclosure for indoor/outdoor installation, AC/DC power converter with 20’ cord included, Liquid crystal display with back light for sensor/trouble status, ambient temperature 35°F to 105°F, for cold water applications. Manual override, Local open/close water control. Flood Sensor: Power using 2 AA Alkaline Batteries or optional AC/DC power converter (sold separately). Batteries will provide back up power upon loss of electricity. Wireless sensors are addressable and supervised for conditions such as water detection, power lost, sensor short/open and low battery. Ten foot sensor cord allows optimal sensor placement. Flood sensors can support one or two sensor wires. Each WaterCop ® PRO actuator valve can support up to 45 wireless sensors. Range Enhancing Repeater: Enhances transmission range of wireless sensors. Plugs into any standard wall outlet. Receives and re-transmits sensor signals from outlying sensors to the WaterCop ® PRO actuator. Monitoring Station-Standard: LCD display with back light provides instant feedback of sensor alarm and trouble conditions as well as open/close status of water supply. Local push button water controls for instant on/ off of water supply. Audible alarm sounds when any sensor detects flooding. Internal mounting bracket mounts to standard wall boxes for aesthetics and cord management. AC/DC power converter with 20’ cord included. Monitoring Station-Hardwired (pictured above): Accommodates up to 8 zones for WPSC hardwired flood sensors (sold separately). NEED NEW PHOTO use an extension cord. The shut-off valve must be installed • In the main water line; • In place of or just downstream from the main water shut-off valve; • Where it is accessible • Where the case is protected from use as a step or from other excessive loads. Local electrical and plumbing codes should be consulted to ensure that the installation is in complete compliance. (See Installation section for details.) Placement of Flood Sensors Each WaterCop ® PRO can support an unlimited number of flood sensors. Additional sensors may be added at any time. A sensor consists of a transmitter and a sensor probe (a small disc at the end of the wire, with two short gold prongs protruding from one side). Flood sensors should be placed in locations where leaks are most likely to occur. Suggested Locations • Washing Machines • Toilets • Dishwashers • Icemakers/Refrigerators • Kitchen Sinks • Automatic Humidifiers • Bathroom Sinks • Water Heaters • Pipes that are prone to freezing (Freeze sensors are also available) The transmitter in the flood sensors and the receiver in the WaterCop ® PRO communicate by radio frequency. The smaller the distance between them, the stronger the signal will be. Transmission distance is somewhat dependent upon the building layout and type of construction. The transmitter (attached to the sensor) must be kept dry. It is NOT splash proof. Sensors should never be placed outdoors. The sensor probe detects the water from a leak and is completely waterproof. Sensor probes should be placed on the floor or in areas where water would tend to accumulate rapidly in common leak or overflow situations. Make sure that any water from a leak will drain toward the sensor probe, not away from it. Avoid high traffic areas where the cord or sensor could be stepped on or kicked and where children or pets may disturb it. The sensor probe should be placed FLAT on the floor so water can be detected as soon as it begins to accumulate. The sensor probe may be secured to the floor with screws. To avoid damage to transmitters and to provide for the strongest signal possible, the transmitter portion of the flood sensor should be mounted in a convenient location (on the wall, in a cabinet, closet, etc.) two to three feet above the floor (see illustration). (See Installation section for details on sensor installation.) Hard Wired Sensors: Ten foot white cord with single sensor. PRO sensors are easily secured to floor using mounting holes. Sensors provide the same feedback to monitoring station as the wireless WaterCop ® PRO sensors. Use hardwired censors for convenience or if conditions prevent wireless communication. Sensors sold individually and can be wired with up to 200 feet of 22/24 AWG 2-conductor cord (not included). General Safety Information Warning Do not apply electrical power to the unit unless the unit is fully assembled. Failure to do so could result in personal injury and/or damage to the unit. Warning Disconnect power source before working on or servicing the unit. Failure to do so could result in personal injury. Caution It is strongly recommended that eye protection be worn while servicing the system. Failure to do so could result in personal injury. How the System Works Flood sensors constantly monitor their selected areas for accumulating moisture. When a leak is detected, a sensor will send a radio frequency signal to the WaterCop ® PRO unit instructing it to shut off the water supply to the home. The WaterCop ® PRO valve will remain closed until it is manually reset. The flood sensors are a battery powered device enabling it to be located anywhere a leak is likely to occur, or where water might cause damage. The WaterCop ® PRO requires household electrical power (common 115 VAC, grounded outlet) and will not operate during a power outage. Selection of WaterCop ® PRO Installation Sites The WaterCop ® PRO valve should be installed in the main water line just downstream from the main shut- off valve in y…

HOW THE EUT MEETS THE REQUIREMENTS OF 15.31 (e) FOR THE DYNAQUIP CONTROLS RANGE ENHANCING REPEATER MODEL: WPR The fundamental was maximized on the Lab D test site using a normal test setup with the EUT connected directly to the AC public mains (115 Vac). Next, the EUT was then connected to the Staco Energy Products Variable Auto Transformer Model: 3PN1010. The Variable Auto Transformer allows the Vac input to be varied. The AC input was then dropped to 85% (97.75 Vac) and raised to 115% (132.25 Vac). The actual AC input was measured using a calibrated Fluke Multimeter Model: 87, Serial Number: 956410240, Calibration Due Date: May 28, 2010. The fundamental was then verified again to see that the amplitude did not change. Test Result: The EUT does NOT change amplitude at the fundamental when the AC input voltage is varied between 85% and 115% of the input nominal rated supply voltage.
