B-AQUASAFE (DMR)

A fully integrated solution, from Man-In-Water detection, to alarm dispatching and escalation to the fire brigade department.

BLUETOOTH MAN-IN-WATER DETECTOR

The B-Aquasafe product line is used in the fish framing industry to detect a man-in-water and broadcast the alarm using the UHF/VHF radio carried by the operators. The Man-In-Water detector is connected to the handheld radio via bluetooth which has several advantages over the previous wired sensors.

Advantages
The radio-sensor connectivity is done via Bluetooth leaving the radio PTT/headset port available. This solution is appreciated by operators who are now able to combine the safety requirement of a man-in-water-detector with the use of hardwired audio-microphone headsets.
The bluetooth sensor is completely water-proof. The wireless connection is more robust and removes all corrosion issues that could have alterned the propagation of the man-in-water alarm.

Limitations
-The sensor is now running on its own battery which needs to be recharged. Sensors are equipped with an induction charger sold seperately. Expected battery life is 250 hours.

-Pairing. The user needs to pair its sensor with its radio prior to every shift. Although the sensor is equipped with a bluetooth handshake LED feedback, user are recommended to test their Man-In-Water alarm prior to every shift to ensured that they have established connection with the right sensor instead of their co-worker!

Please read the safety procedure manual.

CONFIGURATION

SENSOR CONFIGURATION

B-Aquasafe sensors are pre-configured in the factory. No additonal work on the sensor is required.

RADIO CONFIGURATION

In order for your Man-in-Water detector to work, your radio needs to be upgraded with an inside chip also called “GOB”. Please contract your radio resseller to ensure that your radios are B-Aquasafe ready!

HOW TO SYNCH THE SENSOR VIA BLUETOOTH?

• Make sure that the sensor is ON using the magnet.

• Open the Radio Menu/Bluetooth connected device

• Scan Devices

• Select the sensor name for example: BT-SNR-00##

• Receive a message confirmation from the radio that the device is connected (first bip when BT device detected, second bip when handshake succesful).

• Test that your sensor is ready be putting your sensor in contact with sea water to trigger the PRE-ALARM.

CHARGING⚠️

Using an induction charger

The sensor is equiped with an induction charging mechanism to facilitate operations on fit into the life-jacket pocket. The life jacket is designed to fit an induction charger to allow charing without having to remove the sensor from its pocket. Make sure to witness the LED feedback signal to confirm that the sensor is charging. (charging mode = WHITE LED)

Proximity

The proximity of the bluetooth water detector with the radio is an important limitation to take into consideration during operations. The bluetooth connection should remain within the range of 15 cm from the radio bluetooth receiver. This safety distance is to ensure a good communication with the sensor while submerged.

Induction charge

While induction charging has many advantages, it is important to position the sensor propertly on its induction charger to induce the charge. An LED confirms that the charge is ACTIVE when the light is ON. The induction charger also has a charging LED mechanism indicating that the sensor is charging.

Water sealing

The sensor is sealed to resist the marine environment and resist a possible drop into water. No firmware update is currently possible under this version of the water detector.

HOW TO USE IT?

The sensor will reach a full-charge after a continuous 3H-charge at 10 mAh. The charging LED will turn off to indicate that the battery is fully charged.

MAGNETIC SWITCH

The sensor can be turned on using a magnet. The magnet should be positioned on the magnetic logo located right next to the LED. The sensor automatically scans for Bluetooth devices.

PAIRING THE BLUETOOTH SENSOR

Start the Motorola DP4601 radio equipped with Bluetooth. Make sure that the prequisites to configure the radio have been met (above).

1. In the radio menu. Activate Bluetooth.

2. Search for Bluetooth devices.

3. Bring the man-in-water detector within the range of the radio. Power the sensor ON. This will bring the sensor into pairing mode. A flashing blue light.

4. Select the BT-SNR-00## device.

5. Choose the ‘connect’ button. As soon as the radio-sensor handshake is over, the sensors appears as connected.

6. Test your pre-alarm by dropping the sensor into sea water. Make sure to catch the pre-alarm if you do not want to trigger a real man-in-water alarm.

7. Your sensor is now ready for operations.

Scroll-down the Motorola Radio menu to activate the Bluetooth. Select the sensor from the list of discovable bluetooth devices.

STOPPING A PRE-ALARM

It is possible to stop the pre-alarm to escalade into an emergency alarm within the first 5 seconds of the pre-alarm. Beyon that lapse of time, the radio switches to emergency mode.

MAN-IN-WATER

When the sensor is contact with water, a pre-alarm is triggered on the radio. Five seconds later, the alarm escalades to the level of an emergency alarm and is broadcasted accross all active radios of the same call group.

Communications are interrupted by an audible alarm. The Radio LED located next to the antenna is blinking red. The LCD radio screen displays an alarm banner ‘man-in'-water’.

The Man-In-Water radio when switching to emergency mode, automatically enters into a PTT voice loop to enable voice communications without having to press the PTT button.

STATE-MACHINE

Once the Sensor is Turned-ON, it moves to Discovery State trying to pair with a radio via bluetooth. The pairing needs to be confirmed from the radio Bluetooth/Devices/Find Devices, select the sensor, connect.

Once connected, the sensor is ready to detect a man-in-water and switch to a Alarm State (RED LED flashing below). When the sensor is out of the water, it automatically switches back to an Idle State.

The seven modes can be represented as follow:

CHANGING THE SENSOR NAME

All man-in-water detector come with a pre-defined sensor name which is printed on the back of the sensor enclosure.

MEASURING SENSOR BATTERY LEVEL

Request the battery level by typing * BATT * on the radio keyboard.
