Fibaro FGFS-101 Flood Sensor

Introduction

The Fibaro Flood Sensor is a universal, Z-Wave compatible, flood and temperature sensor. It can be powered by battery (approximately 2 years of battery life) or a VDC power source (12 or 24 VDC). A flood alarm is sent to Z-Wave network devices or additionally to any alarm system controller via an NC contact. The device includes a built-in temperature sensor for monitoring ambient temperature, such as floor temperature. It is designed for placement on the floor or wall, with the flood sensor probe extendable by a wire. The sensor features an LED indicator and an acoustic alarm. It is also equipped with a tilt sensor that reports tilt or movement to the main controller, for example, if the sensor is moved from its original location. The LED indicator signals flood events, operating modes, or Z-Wave network communication range. The Fibaro Flood Sensor is designed to float on water, ensuring it continues to send alarm signals even in substantial inundation.

I. General Information About Fibaro System

Fibaro is a wireless system based on Z-Wave technology, offering several advantages over similar systems. Unlike typical radio systems that rely on direct connections, which can be weakened by obstacles like walls or furniture, Fibaro devices act as both transmitters and receivers, duplicating signals. This mesh networking capability allows connections to be established through intermediate devices if a direct path is unavailable. Fibaro is a bi-directional system, meaning signals are confirmed upon reception, verifying device status. The transmission safety is comparable to wired data bus systems. Fibaro operates in a free data transmission bandwidth, with frequencies varying by country. Each Fibaro network has a unique network identification number (home ID), enabling multiple independent systems to coexist without interference. Z-Wave is a recognized standard, similar to Wi-Fi, adopted by many manufacturers, ensuring system compatibility and extensibility. More information is available at www.fibaro.com. Fibaro systems generate a dynamic network structure, automatically updating component locations in real-time via status confirmation signals.

II. Z-Wave Network Inclusion

The TMP button is used to include the Fibaro Flood Sensor into the Z-Wave network. The device can also be included via auto inclusion mode when a DC power source is connected (this mode is active only after the built-in battery has been disconnected).

Including the Fibaro Flood Sensor using Auto Inclusion Mode:

1. Ensure a DC power source is disconnected and the sensor is within direct communication range of the main controller. The battery must be removed.
2. Open the cover.
3. Set the main controller into learning mode (refer to the main controller's operating manual).
4. Connect a DC power source to include the Fibaro Flood Sensor into the Z-Wave network in autoinclusion mode.
5. The Fibaro Flood Sensor will be detected and included.

? In case the Sensor is not detected, proceed to manual inclusion (described below) or reset the Sensor and repeat the auto inclusion procedure.

To deactivate auto inclusion mode, press the TMP button once after connecting the DC power supply.

Manual Z-Wave Network Inclusion:

1. Connect a DC power supply to the Fibaro Flood Sensor or insert a battery. Ensure the sensor is within the Z-Wave network's main controller's range (refer to the main controller's operating manual).
2. Set the main controller into learning mode.
3. Triple-click the TMP button.
4. The Fibaro Flood Sensor will be detected and included.

III. Z-Wave Network Exclusion

To exclude a Fibaro Flood Sensor from the Z-Wave network, follow these steps:

1. Remove the sensor's cover.
2. Ensure the sensor is connected to a battery or a DC power supply.
3. Set the main controller into learning mode (refer to the main controller's operating manual).
4. Triple-click the TMP button located inside the Flood Sensor's casing.

IV. Sensor's Installation

1. Remove the top cover.
2. Include the sensor into the Z-Wave network (see Section II).
3. Place the sensor onto a surface prone to flooding. All three electrodes underneath the device should evenly touch the surface.
4. If the sensor is to be DC powered, drill holes in its casing and connect wires according to wiring diagram no.2.
5. Close the sensor's casing.

? After completing installation, it is recommended to test the sensor's operation by placing the entire sensor or its probes' extension wire onto a water surface.

? The Sensor detects resistance (under 4MΩ) between electrodes 1 and 3, 1 and 2 (according to scheme no.4), and electrodes connected to contacts (SENS1 and SENS2).

? Contacts SENS1 and SENS2 are dedicated to flood detection only. Do not connect external voltage.

? When changing the Sensor's location, it is recommended to wake up the device and reconfigure the Z-Wave network by triple-clicking the TMP button.

? The TMP button has two functions: 1) Including / Excluding the device into / from the Z-Wave network. 2) Tamper contact for the II-nd Association Group. When a sensor is included into the Z-Wave network, case opening alarm may be activated (according to parameter 74 settings).

V. Powering Mode Information

The Fibaro Flood Sensor operates in two powering modes: default battery power or constant current via a 12/24 VDC power supply connected to the +12 and GND terminals (see diagram no.2). Powering mode configuration is automatic during Z-Wave network inclusion. In battery mode, the sensor communicates periodically with the main controller; alarms are sent immediately, but configuration and association settings are updated at specified wake-up intervals or manual wake-ups (triple TMP click). In DC powering mode, configuration and association parameters are sent as needed, and the sensor acts as a Z-Wave signal repeater.

Switching to a Constant Current Powering Mode:

1. Exclude the sensor from the Z-Wave network.
2. Connect a constant current power source (12/24 VDC) to the +12 and GND terminals, observing wiring diagram no.2.
3. Include the Fibaro Flood Sensor into the Z-Wave network.

In constant powering mode, the sensor can operate without a battery, though installing one is recommended as an emergency power source. If constant power fails, the sensor automatically shifts to emergency mode, sending all reports immediately but disabling configuration and association changes until power returns. Signal repeating function is deactivated in emergency mode.

? Fibaro Flood Sensor will automatically exit emergency mode once 12/24 VDC at +12 and GND terminals is detected (according to diagram no.2) and the device wakes up after detecting an event, i.e., flood alarm, temperature report, tilt, or manual wake-up using the TMP button.

Battery Tips

Fibaro Flood Sensor's battery life is approximately 2 years at factory default settings. The current battery level is displayed in the Home Center 2 interface. A red battery icon indicates the need for replacement. To avoid triggering the tamper alarm during battery replacement, associations for the II-nd association group must be deleted, and the sensor's parameter configuration set to default. Alternatively, the sensor can be powered by a VDC power source (12/24 VDC), in which case the battery serves as an emergency power supply.

? Mounting screws shown in diagram no.3 are not included in the package. Choose a screw type depending on the building material it is being attached to.

VI. Fibaro Flood Sensor Reset

The reset procedure deletes EPROM memory, including all information about the Z-Wave network and the main controller.

Fibaro Flood Sensor's Reset Procedure:

1. Ensure the Sensor is powered.
2. Press and hold the TMP button for 15 - 20 seconds. The LED indicator will glow yellow to confirm entering the 4th sub-menu.
3. Release the TMP button.
4. Click the TMP button once.

The LED indicator glowing red and then turning off confirms a successful reset. Reset completion is also confirmed by an acoustic signal, similar to when the power source is connected.

? Reset procedure does not remove the Sensor from the Z-Wave network's main controller memory. Prior to reset, the sensor must be deleted from the Z-Wave network.

VII. Operating Through the Z-Wave Network

The Fibaro Flood Sensor is a multichannel device featuring both flood and temperature sensors. In the Z-Wave network's main controller, the Sensor will appear as two separate devices.

Diagram Description: Fig. 5 Flood Sensor icon in HOME CENTER 2: Shows the icon representing the Flood Sensor within the Home Center 2 interface.

VIII. Associations

Through associations, the Fibaro Flood Sensor can control other Z-Wave network devices, such as Dimmers, Relay Switches, Roller Shutters, RGBW Controllers, Wall Plugs, or scenes (scenes only via the Home Center 2 main controller).

? Association allows for direct communication between Z-Wave network devices without the main controller's involvement. This mechanism enables the Fibaro Flood Sensor to communicate with other devices even if the main controller is damaged, for instance, in case of a fire.

The Fibaro Flood Sensor supports three association groups:

• 1st Association Group: Assigned to device status, sending BASIC SET (default) or ALARM control frames to associated devices.
• 2nd Association Group: Assigned to the TMP button and tilt sensor, sending ALARM GENERIC control frames to associated devices when the TMP button is released or the tilt sensor is triggered (depending on parameter 74 settings).
• 3rd Association Group: Reports the device status and allows assignment of a single device (the main controller by default), to which the device reports its status.

The Fibaro Flood Sensor allows controlling up to 5 regular and 5 multichannel devices per association group, with one field reserved for the Z-Wave network main controller. To add an association using the Home Center 2 interface, navigate to device settings and click the relevant icon, then select the "device options" tab. Specify the group and devices to be associated. Sending relevant information to devices in association groups may take several hours, depending on configuration parameter settings.

IX. LED Visual Signals and Settings

The Fibaro Flood Sensor is equipped with an LED diode that signals its operating modes and alarms. The LED indicator can also display Z-Wave network range and current temperature.

LED Indicator Signaling Modes:

• Flood alarm: Indicated by alternating white and blue light.
• Battery powering mode (with parameter no.63 set to 1): Periodically shows temperature readouts (depending on parameters 50, 51, 61, and 62 settings).
• Constant powering mode: Continuously signals current temperature with a color determined by parameters 50, 51, 61, and 62 settings.
• Currently chosen MENU position: Indicated by an illumination color. Press and hold the TMP button for at least 3 seconds to enter MENU. Each position within MENU is signaled by a different LED color.

MENU Positions:

• WHITE: Entering MENU confirmation.
• GREEN: Cancel alarm for associated devices.
• PINK: Z-Wave network's range test.
• YELLOW: Sensor reset.

X. Cancel Alarm for Associated Devices

It is possible to cancel alarms for associated devices by entering the MENU, signaled by a GREEN illumination.

XI. Z-Wave Range Test

The Fibaro Flood Sensor has a built-in Z-Wave network main controller's range tester. Follow these instructions to test the main controller's range:

1. Press and hold the TMP button for 10 - 15 seconds, until the LED indicator color changes to violet.
2. Release the TMP button.
3. Click the TMP button.
4. The LED indicator will signal the Z-Wave network range (see description below).
5. To exit the Range Tester, click the TMP button.

Z-Wave Range Tester Signaling Modes:

• LED Indicator pulsing green: Fibaro Flood Sensor attempts to directly communicate with the main controller.
• LED Indicator glowing green: Fibaro Flood Sensor is directly communicating with the main controller.
• LED Indicator pulsing yellow: Fibaro Flood Sensor tries to establish routed connection with the main controller through intermediary devices.
• LED Indicator glowing yellow: Fibaro Flood Sensor communicates with the main controller through other, intermediary devices. After two seconds, the Sensor will retry to directly connect to the main controller, signaled by the Indicator pulsing green.
• LED Indicator pulsing violet: Fibaro Flood Sensor communicates at the range limit. If connection is successful, it will be confirmed with a yellow glow. Using the sensor at the range limit is not recommended.
• LED Indicator glowing red: Fibaro Flood Sensor is unable to connect to the main controller directly or through other Z-Wave network nodes.

XII. Sensor Operation Warning

By default, the flood sensor's insensitivity is set to 1 second, meaning flooding is reported one second after detection. The tilt tamper is insensitive to minor vibrations and turns. After activation, its insensitivity is turned off for 15 seconds. Following this period, any sensor movement will trigger an audible alarm consisting of 3 brief acoustic signals.

XIII. Battery Use Warning

The Fibaro Flood Sensor is a battery-powered device. Using batteries other than specified may result in explosion. Dispose of properly, observing environmental protection rules.

XIV. Advanced Configuration

This section details advanced configuration parameters for the Fibaro Flood Sensor.

Wake up interval (battery mode)

Available settings: 0 or 5 - 86399 (in seconds, 5 s. to 24 hours)

Default setting: 4000 (each 66 minutes)

Defines the time period, in seconds, after which the Flood Sensor will perform a "Wake up" instruction to communicate with the main controller, update parameters, or update software. The sensor will always attempt to connect with the main controller, without retrying if the connection fails. This parameter is relevant for battery operation; a higher Wake up interval means less frequent communication, saving battery life.

Parameter 1: Alarm cancellation delay

Available settings: 0 - 3600 (in seconds, each 1s)

Default setting: 0 (no delay, immediate alarm cancelation)

Parameter size: [2 bytes]

Determines the time period, in seconds, during which the Flood Sensor will retain the flood state after flooding has ceased. The sensor will continue reporting flooding to the main controller. This parameter does not affect acoustic and visual alarms, which turn off immediately after flooding ceases.

Parameter 2: Acoustic and visual signals On / Off in case of flooding

Available settings: 0 - acoustic and visual alarms inactive, 1 - acoustic alarm inactive, visual alarm active, 2 - acoustic alarm active, visual alarm inactive, 3 - acoustic and visual alarms active

Default setting: 3

Parameter size: 1 [byte]

Changing this parameter can increase battery life. Settings changes do not affect the sensor's communication with the main controller; commands to association groups, alarms, and reports will still be sent.

Parameter 5: Type of alarm frame sent to 1-st association group (FLOOD)

Available settings: 0 - ALARM WATER command frame, 255 - BASIC SET command frame

Default setting: 255

Parameter size: 1 [byte]

Determines the type of command frame sent by the Sensor when flooding is detected or cancelled.

Parameter 7: Forced dimming level / roller blind opening level, when sending turn on / open command to 1-st association group devices

Available settings: (1-99) or 255

Default setting: 255

Parameter size: 1 [byte]

The value of 255 allows for turning a device on. For a Dimmer, this means turning it on with the last memorized state (e.g., if a Dimmer was set to 30% and turned off, using command 255 turns it back on to 30%).

Parameter 9: Alarm cancelling or turning a device off (Basic) command frame deactivation.

Available settings: 0 - alarm (flooding) cancellation inactive, 1 - alarm (flooding) cancellation active

Default setting: 1

Parameter size: 1 [byte]

Setting this parameter to 0 stops BASIC SET = 0 or ALARM WATER = 0 control frames from being sent. After sending a flood alarm report, the device will continue reporting flooding after it has ceased. This state can be cancelled by choosing alarm cancelation from the MENU (marked with green LED color).

Parameter 10: Temperature measurement interval

Available settings: 1 - 65535 (in seconds)

Default setting: 300 (5 minutes)

Parameter size: 2 [bytes]

Determines the time interval, in seconds, at which the Flood Sensor measures and reports ambient temperature and battery level. A new temperature value is reported if it differs from the previously measured value by the hysteresis defined in parameter 12. If the battery level changes, a battery status change report is sent. This parameter is relevant for battery power mode; a longer interval means less frequent communication, extending battery life.

Parameter 12: Temperature measurement hysteresis

Available settings: 1 - 1000 (each 0.01°C)

Default setting: 50 (0.5°C)

Parameter size: 2 [bytes]

Determines the minimum temperature change value (insensitivity level) that triggers a temperature report to the main controller, according to Parameter 10 settings.

Parameter 13: Alarm BROADCAST

Available settings: 0 - broadcasts inactive, 1 - flood (1st Association Group) broadcast active, tamper (2nd Association Group) broadcast inactive, 2 - flood broadcast inactive, tamper broadcast active, 3 - flood broadcast active, tamper broadcast active

Default setting: 0

Parameter size: 1 [byte]

Other than 0 means alarms are sent in BROADCAST mode (with priority over other communications) to all devices within the Fibaro Flood Sensor's range.

Parameter 50: Low temperature alarm threshold

Available settings: -10000 to +10000 (each 0.01°C)

Default setting: 1500 (15.00°C)

Parameter size: 2 [bytes]

Stores a temperature value below which the LED indicator blinks with a color determined by Parameter 61 settings. By default, the LED indicator blinks blue.

Parameter 51: High temperature alarm threshold

Available settings: -10000 to +10000 (each 0.01°C)

Default setting: 3500 (35°C)

Parameter size: 2 [bytes]

Stores a temperature value above which the LED indicator blinks with a color determined by Parameter 62 settings. By default, the LED indicator blinks red.

? The main controller does not interpret negative numbers as decimals. Read values may differ from entered values. Negative numbers are coded in U2 standard.

Parameter 61: Low temperature alarm indicator colour

Available settings: 0 - 16777215

Default setting: 255 (blue 0x000000FF)

Parameter size: 4 [bytes]

? A main controller interprets colors as a sum of its component colors' values. Each color value is a number from 0 to 255. Example: Indicated color = 65536 * RED value + 256 * GREEN value + BLUE value.

Parameter 62: High temperature alarm indicator colour

Available settings: 0 - 16777215

Default setting: 16711680 (red 0x00FF0000)

Parameter size: 4 [bytes]

? A main controller interprets colors as a sum of its component colors' values. Each color value is a number from 0 to 255. Example: Indicated color = 65536 * RED value + 256 * GREEN value + BLUE value.

Parameter 63: Managing a LED indicator under standard operation

Available settings: 0 - LED indicator doesn't indicate the temperature, 1 - LED indicator indicates the temperature (blink) every Temperature Measurement Interval (Parameter 10, constant current and battery) or Wake Up Interval (battery mode), 2 - LED indicator indicates the temperature continuously, only in constant power mode.

Default setting: 2

Parameter size: 1 [byte]

Parameter determines LED indicator's operation. Set to 0 turns the indicator off, saving battery life.

Parameter 73: Temperature measurement compensation

Available settings: -10000 to +10000

Default setting: 0 (0.00°C)

Parameter size: 2 [bytes]

Stores a temperature value to be added to or deducted from the current temperature measured by the internal temperature sensor to compensate for differences between air temperature and floor level temperature.

Parameter 74: Alarm frame sent to 2-nd Association Group activation (MOVEMENT_TAMPER / BUTTON_TAMPER)

Available settings: 0 - tamper alarms inactive, 1 - button tamper alarm active, 2 - movement tamper alarm active, 3 - button and movement tampers alarm active

Default setting: 2

Parameter size: 1 [byte]

The device can trigger alarms from sensor vibrations (e.g., when moved) or when the TMP button is released. 2nd Association Group alarms are not cancelled.

Parameter 75: Visual and audible alarms duration

Available settings: 0 - 65535 (each 1 second)

Default setting: 0

Parameter size: 2 [bytes]

Determines the time period after which the alarm becomes "quiet" (still active but the device enters battery saving mode). Visual or acoustic alarm will be reactivated after the time period specified in Parameter 76. When the alarm status ceases, the alarm turns off immediately. A value of 0 means visual and acoustic alarms are active indefinitely. In battery power mode, the Sensor will never go to sleep, which may significantly shorten battery life.

? The parameter is ignored when Parameter 2 is set to 0.

Parameter 76: Alarm frame / Basic Set frame retransmission time when retaining flood alarm

Available settings: 0 - 65535 (each 1 second)

Default setting: 0

Parameter size: 2 [bytes]

? If the time period set in this parameter is shorter than the one specified in parameter 75, the device will not quiet the alarm; it will remain active.

Parameter 77: Flood sensor functionality turned off

Available settings: 0 - Default flood sensor operation (flood detection, reactions), 1 - Built-in flood sensor TURNED OFF (does not change its state in the main controller, does not send Alarms and Basic Set frames with flood state changes. Always visible in the main controller as turned off).

Default setting: 0

Parameter size: 1 [byte]

Allows for turning off the internal flood sensor. Tamper and built-in temperature sensor will remain active.
