RSC-900-AW Kit

General questions about the RSC-900:

Will the system work with NEST, Echo, etc.?

Not at this time.

Do you have a local contractor you can recommend?

No, we do not have designated contractors at this time. Any licensed plumber should be able to install the valve.

What is the warranty?

3 years; see RDT’s Standard Terms & Conditions for further details. Batteries are not included under the warranty.

What type of batteries do I need for the system?

All batteries are included in the kit; replacement batteries are all commercial available:

  • Hub: (2) AA Batteries
  • Sensors: (2) AAA Batteries
  • Repeater: (2) AAA Batteries
  • Actuator: (4) CR123A (3v) Batteries

How long do the batteries last?

  • Hub & Repeater: Powered by AC. Battery backup lasts 8 hours in the event of a power outage. We recommend replacing the batteries in the hub and repeater after any significant power interruption to ensure future performance.
  • Sensor: 2 years
  • Actuator: 2 years

Can I use rechargeable batteries?

No, the use of rechargeable batteries is not recommended.

What is the Ohm rating of the water sensor?

Sensitivity of the water sensor has been tested to below 300K.

What is the decibel level on the audible alarm on the sensor?

70 dBA.

What certifications does this product carry?

  • The wireless components are FCC and IC certified.
  • The valves are ANSI 61/Annex G approved.
  • The actuator (RSC-900-AW) is IP68 rated (for outdoor use under certain conditions).

Is the valve lead-free?

All our valves are ANSI 61/Annex G approved and are suitable for potable water applications.

Will the system interfere with or slow down my existing network?

  • No, it should not. However, if you do experience any slowdown or Internet access issues, you should power down your hub (unplug AC and remove batteries) and unplug all other router/Ethernet connections. Next, plug the hub back into the router and power up the hub (AC & batteries). Finally, plug in all other router/Ethernet connections.
  • If problems persist, you should confirm that the IP address of the hub is unique and not the same as any other device connected to the router. Troubleshoot this issue with your router manufacturer.

Will the system work on boat or remote cabin?

In theory, yes.  However, please consider access to 120V AC power for the hub and Internet access requirements

If I move, can I take the system with me?

Yes, you will just need to remove all of the wireless system components (hub, sensors, actuators, etc.) and place them in the new location. Consider leaving the valve in place as it may be easier to purchase and install a new one at the new location (contact RDT for a replacement valve). You will also need to re-establish the Internet connection to the hub at the new location.

What happens if I sell my house and want to transfer the RSC-900 system to the new owner?

The way to handle that situation would be for the new owner to purchase a new hub and establish their own account (contact RDT for more information).

RSC-900 Wireless Set Up and Communication

System configuration and installation:

How many sensors can be added to each system?

A maximum of 29 wireless devices (any combination of sensors, actuators or repeaters) can be added to each hub (maximum of 2 repeaters per hub).

I have a large building and need more than 29 sensors – what should I do?

Multiple systems can run in one building. Contact RDT to discuss your application in more detail.

Can I control more than one actuator and valve assembly per system?

Yes, multiple actuator and valve assemblies are allowed per system.  However, the maximum number of all wireless devices (including actuators, sensors and repeaters) per system is 29.

Can I install the shut-off valve and actuator outside?

Yes, the actuator is rated IP68, which means it can be installed outside. Avoid installations that place the actuator more than 3’ below grade or allow submersion for more than 30 minutes. For installations located areas where high temperatures are common (+100°F), avoid installing the actuator in direct sunlight as the batteries can be affected.

Where is the best place to locate the hub?

Ideally, the hub should be located in a centralized location to the RSC-900 wireless system devices. The hub requires 120V AC electrical power and should be located within reach of a wall plug.  A 6’ Ethernet cable is included in the kit; a longer Ethernet cable may be required if your optimum hub location is more than 6’ from your router.

What is the wireless signal range?

  • 200’ feet between any wireless device (sensor, actuator or repeater) and the hub.
  • The Wireless Signal Repeater will increase the range by 200’ (between any devices).

How do I know if I need a wireless signal repeater?

As part of the standard installation process, the RSC-900 communication software will automatically determine if any device location(s) require the use of a Wireless Signal Repeater. The device/location requiring the signal repeater will be clearly indicated on the RSC-900 app, and a prompt for repeater installation/repeater QR code scan will be present.

Note: You can only install a repeater when the RSC-900 communication software determines it is required. If the system app does not prompt you for repeater installation, it will not allow you to add the device.

Can I change the high/low temperature settings on the sensor?

No, settings cannot be changed. Notifications will sent when the pre-set high temperature of 122°F (50°C) or the low temperature of 36°F (2°C) is reached.

Are there any control outputs (relays, dry contact) for alarms?

Please contact us to discuss your requirement.

I would like to use a Wi-Fi hotspot with the RSC-900 hub. Which one should I get?

If use of a Wi-Fi hotspot is desired, use any commercially available device – preferably one with an Ethernet port. Be sure it is also compatible with the appropriate mobile device service provider. Note that use of a Wi-Fi hotspot requires a local hard-wire connection to an Ethernet port for initial setup.  Click here to download additional Wi-Fi Hotspot Setup Procedure instructions (PDF).

What Wi-Fi standards is the RSC-900 hub compatible with?

The hub was designed for use with Wi-Fi standard 2.4 GHz, IEEE802.11b/g/n. While the latest 5 GHz band is a less congested bandwidth, the shorter waves used with 5 Ghz make it less able to penetrate walls and solid objects. Therefore, we feel the 2.4 GHz band is more suitable and reliable for our leak detection application.

I'm a contractor. Can I set the Account and System up in my office and then install it at my customer's location?

The self-installation software is designed for set-up, installation and operation on one Internet network.  Please contact RDT to learn more about best practices for professional installers.

RSC-900 Valve/Actuator - Parallel Mount

System operation and troubleshooting:

When there’s a fault, how will I know the location of the affected device?

If a location or name for each device was entered into the app upon set-up, finding it should be easy!

What happens if the Internet goes out? Will my system stop working?

No, the leak detection local monitoring and response is not dependent on Internet service. However, app notifications will be stored until such time as the Internet service is restored.

My Internet service stopped working – what should I do?

Contact your Internet service provider.

Can the valve be operated manually?

Yes, there are several ways to manually operate the valve.

  • First, the app allows you to open or close the valve.
  • You can press the orange button on the actuator for 5 seconds to open or close the valve.

If the actuator fails to respond per the above, remove the actuator from the valve stem and insert the provided key to manually open or close the valve.

How do I use the manual key to open or close the valve?

Remove the actuator and insert the key into the slot. Turn a 1/4 turn to change valve state. Another 1/4 turn will put the valve back in its original state.

Does the actuator automatically exercise the valve?

Yes. The self-cleaning occurs once a month and will not interfere in any way with normal water demand flow.

How frequently does the system check for faults (water leak, low battery life, abnormal temperature, etc.)?

The system will respond instantly when a water leak is detected (shut down the valve, send an alert, etc). In order to conserve battery life, it periodically checks for other system issues, like battery life, ambient temperature, signal communication strength and connectivity, etc.

Temperature measurements are taken every 8 hours, and alerts are sent out immediately for high and low temperature readings: 37°F (3°C) and 122°F (50°C), ± 3°C.

Battery life is measured on all devices every 4 hours.

Communication between the devices and the hub, and the hub and the cloud, is checked every 30 seconds. The app screen will indicate a communication issue after 3 minutes of lost connectivity, and a push notification will be sent if connectivity remains lost for 60 minutes.

Note: The leak detection devices will continue to communicate with the hub and respond to a water leak even if connectivity to the cloud is lost.

My device is flashing an orange LED, and there is an orange border around it on my app. What does that mean?

Orange LEDs and an orange border in the app indicate a temperature issue at that device location (ambient temperature is too high or too low). Address the temperature issue as soon as possible to return the LED and border back to green.

Note: If the temperature is too low, consider commanding the valve to close in order to avoid water damage from potential frozen pipes.

I received a notification that my system needs a software update. What does that mean?

From time-to-time, we make improvements and minor corrections to the system software. These updates occur “over-the-air” and will not affect the system performance while the update is in process. Users will receive notification on the app and via email that a software update is available, and they have total control of when the update starts through the app. The update is transmitted through the system in many “small packets” of information so as not to adversely affect system battery life. For that reason, it’s perfectly normal for the system update to take several days.

Note:  If the update fails to complete within 5 days, it will automatically time out – contact RDT tech support if this happens to your system.

App-based plumbing leak detection and water shut-off

Mobile app and account management:

Are there any fees associated with the app?

No. The app is a free download, and there are no monthly fees. Standard data rates may apply.

What’s the difference between a System, an App and an Account?

A System consists of (1) hub and its associated wireless devices, which is controlled by an Account. The Account is accessed via the RSC-900 App. Multiple Systems can be controlled by a single Account on one App.

Can I access the app on a PC or Mac?

No, the app works on an iOS or Android smartphone. However, you can check email notification from the system on your PC or Mac.

What type of device does the RSC-900 app run on?

  • The RSC-900 app is available free for iOS or Android.
  • Backwards compatible maximum of 3 releases/versions.

Is the RSC-900 app compatible with tablets and iPads?

The app is designed to run on smart phones.  Depending on your specific tablet or iPad, the app may or may not work.

How do I change the smartphone number used on the account?

The app does not work by phone numbers; the account is tied to the email address used for setting up the system. If you want notifications to appear on another phone or device, simply log into the account from that new device.

Can more than one person receive system notifications and emails?

Yes, one additional contact can receive email notifications if invited by the primary account holder to do so. Alternately, the user name and password can be shared among as many trusted associates as desired, and all will receive notifications and have access to the system functionality.

My email notification from the RSC-900 app displays “FirstName” “LastName” instead of my name. How can I fix that?

From the app menu (three lines in the upper left-hand corner of the app screen), click on My Profile – Edit Your Details. Update the information and tap “Save.”
