Functions

The water presence detection system consists of an inset detector and a wall sensor in radio frequency at the frequency of 868 MHz.

The water sensor detects the presence of water by operating using ultrasounds.

This technology prevents oxidation of the contacts due to humidity and therefore avoids untimely interventions.

The Chorus flood protection system for domestic use allows users to:

• handle one or more water detectors using an RF connection.
• detect the presence of water by installing sensors.
• the use of an internal relay to trigger a solenoid valve with manual reset to intercept the delivery of the water at the point of supply.
• signalling the alarm by means of an audible warning and a light signal.

INSTALLATION INSTRUCTIONS

Water detector features

The detector is fitted with an RF system for receiving signals transmitted by the sensors. On the front there is a programming button, 3 indication LEDs and a buzzer for audible signals. Output relay with hermetic contacts for solenoid valve control. (or other electric supply e.g. a pump)

RF sensor features

The sensor is equipped with:

• A button: this is used by the detector during the sensor acquisition phase (PROGRAMMING), during the operating check phase (TEST) or to cancel possible alarms. Pressing the key on the sensor during the TEST phase must be rapid, while during the PROGRAMMING phase the key must be kept pressed for at least 5 seconds.
• LED: this shows the operating status and remains on for a few seconds during FLOOD-ING ALARM and SENSOR PRESENT transmissions, blinking for signalling BATTERY FLAT. The power supply is provided by a 9V battery (not included in the pack) with a life of approximately 1 year.

To optimize the sensor's autonomy, the liquids present search operation and the immediate transmission of the alarm signal to the detector is done at 2 minute intervals. In the worst case, therefore, the alarm is generated within a maximum of 2 minutes from the instant the sensor detects the presence of liquids.

The sensor sends the following information relative to its status to the detector:

• Alarm: during this transmission the LED on the sensor switches on for a few seconds.
• Sensor presence + sensor faulty or battery flat: this information is transmitted to the receiver every 12 hours.

INSTALLATION INSTRUCTIONS

Detector assembly

The detector must be installed on Chorus supports (minimum 2 modules) and completed with finishing plaques (ONE, LUX or ART).

INSTALLATION INSTRUCTIONS

Sensor assembly

The sensor must be positioned flush with the floor so that it can detect the presence of liquids, in such a position that the LED is well visible and the button accessible. Before definitively fixing the sensor to the wall it is advisable to check the RF connection with the detector. To do this requires carrying out the sensor acquisition procedure and a test from the position where the sensor will be installed (see following paragraphs).

Double fixing possibility: From above 3-4 From left-hand side 3-4

NOTE: The first time the product is powered-up or when the "sensor-detector" communication is particularly DIFFICULT, it is recommended to check during installation that sensor and detector communicate properly (see "faulty sensor test and identification" procedure).

USER INSTRUCTIONS

Control description

Light signals

green

Detector powered up and in normal operating conditions.

green
yellow

In the case of a fault, malfunction or flat battery in a sensor, the yellow LED blinks and an intermittent audible alarm is activated until it is silenced by pressing the front button or the fault is resolved.

green

Test.

The green LED blinks after prolonged pressure of the front button for approximately 5 seconds.

Light signals

Programming.

Pressing the button for approximately 5 seconds during the "test" phase causes a move to the programming phase.

Detector cut-out.

Rapidly pressing the button disables the detector. The detector returns into service when the button is pressed again or automatically after a time interval of 24h.

The operation is useful for avoiding false alarms in cases of maintenance or in cases of cleaning the room.

Alarm.

On arrival of the alarm signal from a sensor the audible alarm is activated and the red LED blinks.

In the case of an alarm it is necessary to identify the reason that has caused it and act accordingly.

Operating modes and signals

The presence of power and therefore operation of the detector is shown by the green LED fixed on.

If there is no power the detector will not work, but all the parameters remain stored.

The system restarts automatically when power is restored.

SENSOR ACQUISITION

To access sensor acquisition mode the detector's key must be kept pressed for 5 seconds so that the green LED blinks (TEST function); press the key again for another 5 seconds so that the yellow LED comes fixed on (PROGRAMMING function).

Keep the button on each sensor pressed for approximately 5 seconds to send the identification code to the detector: an audible signal (short but strident) signals successful reception by the sensor.

The maximum number of sensors that can be installed is 5.

To end the PROGRAMMING phase and return to operating mode press the detector button (where 5 sensors are configured, the programming phase is automatically exited as soon as you have completed the last configuration).

The absence of signals or commands for more than 3 minutes causes automatic exit from the PROGRAMMING function.

It is not possible to insert the same sensor more than once.

Whenever the PROGRAMMING phase is accessed, all the sensors present are cancelled and the acquisition operation must be repeated for all the sensors.

FAULT SENSOR TEST AND IDENTIFICATION

To identify a faulty sensor (namely one that does not transmit) or to check the efficiency of the system, the TEST function must be accessed by keeping the detector's key pressed for 5 seconds (the green LED will blink).

Then press the single buttons present on the sensors in succession: if the sensor is perfectly operational the detector outputs an audible signal of successful reception, no signal is output if the sensor is faulty or with a flat battery.

The absence of signals or commands for more than 3 minutes causes automatic exit from the TEST function.

Operating modes and signals

FLAT BATTERY ALARM AND ITS RESETTING

The flat battery situation is signalled both by the LED (on the sensor) blinking until the battery is replaced and by the yellow LED on the detector blinking and the simulta-neous output of a slight and intermittent sound signal (buzzer type) that can only be silenced by the key on the detector itself.

The detector's yellow LED will continue to blink, even after silencing, until the battery is replaced.

To reset the battery flat alarm after battery replacement, it is necessary to make a test of the sensor in the alarm situation by accessing the TEST function or waiting a maximum of 6 hours for automatic reset.

Operating modes and signals

SENSOR FAULTY ALARM AND ITS RESETTING

The sensor sends a presence signal every 12 hours.

If the detector does not receive the signal, the yellow LED starts to blink and the buzzer outputs a slight and intermittent sound (buzzer type) that can only be silenced by the key on the detector itself.

To identify the faulty sensor and subsequently to reset the alarm (after having reset the device), it is necessary to make a test of the sensor in the alarm situation by accessing the TEST function or waiting a maximum of 6 hours for automatic reset.

If the faulty sensor has to be replaced, it is necessary to reacquire all the sensors (PROGRAMMING function).

FLOODING ALARM AND ITS RESETTING

The detector in alarm situation is signalled by the blinking of the red LED and the output of an acute and prolonged sound with an intensity of approximately 70dB.(reading taken at 1 metre).

The output relay is excited by switching its NO/NC contacts.(and therefore the solenoid valve is closed).

The alarm is silenced by pressing the key on the detector.

After silencing, only the visual signal remains (red LED blinking) and the relay contact remains closed for as long as the sensor continues to detect the presence of water.

If the flooding alarm is never silenced, the buzzer will continue to sound at maximum for 3 minutes while the relay and blinking red LED remain active for as long as there is the presence of water.

REMOTE CONTROL

To send an alarm SMS, use a GW 90 821 remote control unit.

Please refer to the remote control instruction manual for connection procedures.

USERINSTRUCTIONS

Prescriptions for correct use

• Do not open or tamper with the appliance: danger of electric shock and malfunctioning.
• Only use a slightly damp cloth for cleaning the appliance.

Advice on positioning

The Chorus water detectors must be installed about 1 metre from the floor (standard height for control devices).

Signal transmission examples

RF Sensor capacity (in free-field conditions)

WARNING:

When installing the various detectors it is important to check the correct wireless range capacity for each sensor towards the detector.

Decreased and critical wireless signal level with regards to different building materials:

with walls in plywood, plasterboard or hollow panelling ...

...range of full capacity from 100% to 90%

with walls in brick or perforated blocks...

...range of full capacity from 95% to 65%

with walls in reinforced concrete

...range of full capacity from 70% to 10%

SOLUTION 1

SOLUTION 2

NOTE: In a system made with several RF sensors connected to one detector only, check the correct communication between the devices; should one or more sensors have some trouble in the communication with the detector, it is advisable to install further detectors in the house in order to ensure a proper coverage (solution 2).

Area of coverage

HORIZONTAL DISTRIBUTION

Wrong

By installing the detector in a decentralised position the sensors located in the opposite side of the house may be too far and may not be able to send a good signal due to the architectural and/or structural impediments.

Correct

By installing the detector in a barycentric position in respect to the sensors, the distance between the devices decreases, thus improving communication.
