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 LTE radio networks available along the coastline. The Person-In-Water detector is connected to the TLK110 handheld LTE device 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-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 separately. Expected battery life is 48 hours.

-Pairing. The user needs to pair its sensor with its TLK110 device prior to the first use. 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 additional work on the sensor is required. Please ensure that your sensor is shows the TLK110 label on the back-side of the sensor.

TLK110 device configuration

In order for your TLK110 to connect to the man-in-water sensor, please configure your Wave portal terminal to designate which sensor to connect to.

HOW TO PAIR the sensor with the tlk110?

• Turn-ON the TLK110.

• Turn-ON the water sensor using the magnet.

• The TLK110 pairing procedure is automatic. The sensor will move from paring mode long blue flashing, to connected mode (short blue flashing).

• Please note that the first paring requires the Wave Portal configuration where the bluetooth devices are designated using their name and mac-address. See further below.

• Test that your sensor is ready be putting your sensor in contact with sea water to trigger the 4-second PRE-ALARM. The pre-alarm can be stopped within 4 seconds by short press the alarm button on the TLK110.

• Your sensor+TLK110 is now ready for operations.

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.

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 4 seconds of the pre-alarm by pressing the TLK110 Emergency Button (short-press). Beyond 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. Four seconds later, the alarm escalades to the level of an emergency alarm and is broadcasted across all active radios of the same call group.

Communications are interrupted by an audible alarm. The TLK110 LED located next to the antenna is blinking red. The LCD screen displays the Emergency Alarm Message.

STATE-MAchine

Once the Sensor is Turned-ON, the water sensor moves to Discovery State trying to until pairing with the TLK110. The TLK110 pairing is automatic. No action from the user is required.

Once connected, the sensor is ready in idle state. Ready to detect a person-in-water. Once in contact with water, the sensor switches to Pre-Alarm State and 4-seconds later to Alarm State (RED LED flashing below). Taking the sensor out of the water will not prevent the Pre-Alarm to be converted into an Alarm unless the Pre-Alarm Stop button is pressed.

However, as soon as the sensor is out of the water, the sensor is ready to detect a new alarm without re-arming mechanism.

The Sensor can access on of these other modes, charging, fully charged, error, charging, not charing or battery low at anytime.

In a nutshell, 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 front of the sensor enclosure. Typically, the sensor naming convention is made of ###-sensor

NON DATAMATIK RADIOS

For our customers that purchased their radios from another radio distributor, the Man-In-Water firmware is available on demand. Please contact your radio dealer for a quotation indicating your radio serial number(s).
