1: Description and Features

ℹ️ This device may be used with all devices certified with the Z-Wave Plus certificate and should be compatible with such devices produced by other manufacturers.

ℹ️ FIBARO Flood Sensor is a Security Enabled Z-Wave Plus product and a Security Enabled Z-Wave Controller must be used in order to fully utilize the product.

The FIBARO Flood Sensor is a universal, Z-Wave Plus compatible, flood and temperature sensor. It can be powered by battery, a 12/24V DC power supply, or both. A flood alarm can be sent to Z-Wave network devices or an external system via a potential-free NC contact using external power. The device includes a built-in temperature sensor for monitoring ambient temperature. It is designed for placement on the floor or wall mounting (with extended probes). The sensor features a visual LED indicator and an acoustic alarm. A tilt sensor reports tilt or movement to the main controller, acting as a theft protection mechanism. The FIBARO Flood Sensor is sink-proof, meaning it floats on water and continues to send alarm signals during inundation.

4: Diagrams and Connection

⚠️ Connecting the FIBARO Flood Sensor in a manner inconsistent with the manual may cause risk to health, life, or material damage.

Notes for the diagrams and probes marking:

Connection to a constant power source:

Connect a 12/24V DC adapter to the [+12V] and [GND] terminals.

⚠️ CAUTION: Connect while observing the wiring diagram shown in this manual only. Incorrect wiring may be dangerous or result in device breakdown. Remember to keep the device away from water or protect holes for wires from water to avoid destroying the device.

⚠️ CAUTION: To prevent accidental pulling out, make certain that cables are firmly attached to the wire connectors and screws are properly tightened. Secure the power cord after connecting it to the terminal.

ℹ️ The [TMP Button] has two functions: 1. Adding / Removing the device to / from the Z-Wave network, 2. Tamper contact for 4th Association Group. When a sensor is added to the Z-Wave network, cover open alarm may be activated (according to parameter 74 settings).

Connection with external wired system:

The [ALARM NC] and [TAMP NC] terminals can be used for integration with an external system hub.

ℹ️ Mounting screws shown in the diagram are not included in the package. Choose a screw type depending on the building material it is being attached to.

ℹ️ The Sensor detects electrical conductivity between electrodes 1 and 3, 1 and 2, and electrodes connected to contacts ([SENS1] and [SENS2]).

⚠️ CAUTION: Contacts [SENS1] and [SENS2] are dedicated to flood detection only. Do not connect external voltage!

Extending Flood Sensor contacts with a wired probe:

If you want the device to be mounted on a wall or in a distance from the flooding source, the sensor should be extended using an external probe (not included). We recommend using extension probes or cables designed to detect water. Probes ends should be coated with non-corrosive metal. Connection wires should not be longer than 3m with 18-26AWG (0.14 - 0.82mm²). This applies also to VDC power source wires.

5: Powering Modes

There are two powering modes for the Flood Sensor: battery (factory included) and constant voltage (after connecting a 12/24V DC power supply to [+12V] and [GND] terminals).

Powering mode configuration is carried out automatically when the device is added into the Z-Wave network.

Switching to constant voltage powering mode:

  1. Remove the sensor from the Z-Wave network.
  2. Connect a constant voltage power source (12/24 VDC) to [+12V] and [GND] terminals in accordance with "Diagrams and connection" on page 7.
  3. Add the sensor to the Z-Wave network.

The Flood Sensor may operate without a battery if a 12/24V power supply is connected. Installing a battery is recommended as it serves as an emergency power source. When constant power fails, the sensor automatically shifts to backup power mode. All reports, including flood and temperature, will be sent immediately, but configuration or association settings cannot be modified until constant power returns. Z-Wave signal repeating is not possible in this mode.

FIBARO Flood Sensor's battery life is estimated at about 2 years at factory default settings. Current battery level is displayed in the Z-Wave controller interface. A red battery icon means the battery needs replacement. To avoid triggering a tamper alarm while replacing the battery, 4th association group's associations must be deleted and configuration parameters restored to default settings.

⚠️ CAUTION: Using batteries other than specified may result in explosion. Dispose of properly, observing environmental protection rules.

ℹ️ The Flood Sensor will automatically exit emergency mode once 12/24 VDC at [+12V] and [GND] terminals is detected.

6: Operating the Device

Controlling the Flood Sensor using the [TMP Button]:

The Flood Sensor is equipped with the [TMP Button], which allows performing the following actions:

Controlling the Flood Sensor with FIBARO Home Center controller:

The Flood Sensor has two built-in sensors: flood and temperature. In the Home Center controller, the Sensor will be shown as two devices.

ℹ️ By default, flood sensor's insensitivity is set to 1 second, meaning flooding will be reported one second after detection. Tilt tamper is insensitive to minor vibrations and turns. After its activation, insensitivity is turned off for 15 seconds. After that, each Sensor's movement will trigger an audible alarm, consisting of 3 brief acoustic signals.

Visual indications:

The Flood Sensor is equipped with a LED diode, signalling sensor's operating modes and alarms. The visual indicator may also inform of the Z-Wave network range and the current temperature.

Visual indicator signalling modes:

Menu Operation:

The menu allows performing Z-Wave network actions. To use the menu:

  1. Press and hold the [TMP Button].
  2. Wait for the device to indicate the desired position with a colour:
    • WHITE - confirmation of entering the menu
    • GREEN - cancel alarm for associated devices and the controller (only if the device is no longer flooded)
    • VIOLET - Z-Wave network's range test
    • YELLOW - full reset
  3. Release the [TMP Button].
  4. Click the [TMP Button] to confirm selection.

Waking up the Flood Sensor:

When in battery mode, the Flood Sensor needs to be woken up to receive information about new configurations from the controller, such as parameters and associations. To wake up the sensor manually, click the [TMP Button] located inside the housing. The device will also wake up and update its data upon startup when added in battery mode.

Resetting the Flood Sensor:

The reset procedure restores the device to its factory settings, deleting all information about the Z-Wave controller and user configuration.

  1. Make sure the sensor is powered.
  2. Press and hold the [TMP Button].
  3. Wait for the visual LED indicator to glow yellow (4th position of the MENU).
  4. Release the [TMP Button].
  5. Click the [TMP Button] once to confirm selection.
  6. After a few seconds, the device will restart with factory settings, signalled by the red visual indicator colour and an acoustic signal ?.

ℹ️ Resetting the device is not the recommended way of removing it from the Z-Wave network. Use the reset procedure only if the primary controller is missing or inoperable. Certain device removal can be achieved by the procedure described in "Adding/removing the device" on page 6.

7: Association

ℹ️ Association ensures direct transfer of control commands between devices, is performed without the main controller's participation, and requires the associated device to be in direct range.

Association (linking devices):

Association allows for direct control of other devices within the Z-Wave system network (e.g., Dimmer, Relay Switch, Roller Shutter) or scenes (controlled only through a Z-Wave controller).

The Flood Sensor provides association for four groups:

The Flood Sensor in the 2nd to 4th group allows controlling up to 5 regular and 5 multichannel devices per association group, with the exception of "Lifeline", which is reserved solely for the controller (only 1 node can be assigned). It is not recommended to associate more than 10 devices in general, as the response time to control commands depends on the number of associated devices.

To add an association (using the FIBARO Home Center controller):

  1. Go to device options by clicking the icon.
  2. Select the "Advanced" tab.
  3. Specify to which group and what devices are to be associated.
  4. Wait for the configuration process to end. Sending relevant information to devices added to associated groups may take even a few minutes.
  5. Wake up the device by clicking the [TMP Button] to speed up the configuration process.

8: Z-Wave Range Test

The Flood Sensor has a built-in Z-Wave network main controller's range tester.

To test the main controller's range:

  1. Press and hold the [TMP Button] until the visual indicator glows violet.
  2. Release the [TMP Button].
  3. Click the [TMP Button] once to confirm selection.
  4. The visual indicator will show the Z-Wave network's range (range signalling modes described below).
  5. To exit Z-Wave range test, press the [TMP Button] briefly.

Z-Wave range tester signalling modes:

⚠️ CAUTION: To make Z-Wave range test possible, the device must be added to the Z-Wave controller. Testing may stress the network, so it is recommended to perform the test only in special cases.

ℹ️ Communication mode of the Flood Sensor may switch between direct and routed, especially if the device is at the limit of the direct range.
