ORCATM (Overboard Recovery Communications Apparatus) is a personal water-activated man overboard (MOB) alarm system developed by BriarTek Inc.
The alarm system includes a signal device transmitter (TX100-base model), a
receiving station (RX100-base model), and an optional direction finder (RDF).
ORCATM aids in the detection, location and recovery of individuals who become separated from the safety of their vessel, and thus exposed to the harsh
elements of the sea. When the alarm is activated, ORCATM transmits an initial
FM message from the victim to the victim's shipboard receiver. The onboard
alarm sounds upon receipt of a valid message. If the wearer of the transmitter
does not disable the alarm within one (1) minute, the ORCATM will begin
transmitting an AM alerting signal that can be received by standard SAR
equipment including most types of RDFs. The ID data will be rebroadcast on
average every minute.
ORCA thus allows for a locally managed MOB situation ensuring that a victim
is recovered quickly so as to minimize effects of exposure. Search and rescue
(SAR) assets outfitted with direction finding equipment are capable of homing
in on the 121.5 MHz emergency frequency to aid in a recovery effort.

TRANSMITTER OPERATION
Parts Overview - See Figure 1.
A. Manual Activation/Test Button (ON)Depress for test purposes to
confirm the operability of
ORCA™ TX 100.
B. Reset Button (OFF) - Depress to reset
ORCA™ from ‘Transmit Mode’
to ‘Armed Mode’.
C. Water Sensors - Detects the
presence of water in a man
overboard situation. Keep
clear of debris!
D. LED/Antenna - Flashing LED
confirms the transmission of
emergency signal during a man
overboard situation or during
operational testing.
Figure 1. ORCA TM TX100
Activation - Insert an alkaline 9-volt battery into the rear panel of ORCA
(all ORCATM TX100s are shipped from the factory with new batteries installed). This will automatically arm ORCATM until activated through a man
overboard situation or by depressing the ON button for manual activation or
operational tests. Once activated, the LED will begin blinking to indicate it is
transmitting an emergency signal. The emergency signal contains identification data tones to be decoded by the matching receiver, in addition to an extended RDF transmission to aid in the location and recovery of the sailor overboard.
Once the device is activated, the LED will flash on and off for approximately
10 seconds. Once the unit begins to transmit an alert it will turn on and stay on
for at least a minute as the unit transmits the alert and ID code to the receiver
using FM mode. Once the ID codes have been sent the unit will transmit an
audible tone in AM mode to allow RDF equipment an opportunity to locate the
device. When the unit is transmitting in AM mode the LED will flash, and
when the unit is transmitting in FM mode the LED will remain illuminated.
Deactivation - The OFF button should generally be used if the transmitter was
unintentionally activated. DO NOT DEPRESS THE OFF BUTTON IF YOU
HAVE FALLEN IN THE WATER. To deactivate ORCATM, simply depress
the OFF button for approximately one second. Continue depressing the OFF
button until the LED powers off.
Notes
NOTE - Deactivation resets ORCATM to its armed mode until activated to
transmit again or until the user removes the battery
Low Battery Indicator - The ORCATM is equipped with an internal low battery
indicator circuit. To determine if the battery needs to be replaced follow these
steps.
1. Activate the unit by depressing the ON
button
2. As soon as the LED begins to flash
depress and hold the OFF button
3. If the LED turns on and remains on for
10 seconds prior to unit shut off, the
battery is still useable. If however the
LED flashes on and off prior to
shutting down, the battery should be
replaced.
Battery Replacement - Using a small Phillips
head screwdriver, unscrew the two battery
door screws on the rear panel of ORCATM. Be
careful not to lose battery door gasket and
screws when replacing battery. Open battery
door and remove used battery by holding
battery connector and disconnecting battery.
See figure 2. Caution: Applying excessive force
on battery lead when disconnecting battery
may break battery lead and cause unit to fail.

Notes
Attach new 9-volt alkaline battery and place in battery housing. Ensure battery
door gasket is correctly seated (see figures 3 and 4). Battery connector lead
should not interfere with seal between battery door gasket and battery compartment (see figures 5 and 6). Close and screw down battery door.

How To Wear The Beacon
The beacon should be worn in a manner such that the beacon will be easily accessible should the person fall overboard. If the user intends the beacon to activate automatically in the water, the beacon should be worn so that the water
sensors would be underwater and the antenna would be above water when the
person is floating in the water.

Automatic Systems Diagnostics
Receiving MOB Transmissions
Connect the antenna to the UHF coaxial antenna connector “E”.
The ON/OFF switch ‘H’ is a rocker switch that, when in the ON position,
powers up the RX100 using 12VDC applied at the 1.3 mm 12VDC jack
“F”. The RX100B also comes with a backup 9VDC battery connector.
The LCD “A” will display “ORCA v___” after the system has initialized.
It will then begin scanning and will remain in this mode until it receives a
MOB transmission.
When a MOB transmission is received, the LCD will indicate which transmitter has been activated and an audible alarm will sound. The alarm is a
piezo-electric buzzer providing a 100 dB alert.
When an alarm is received, the user should depress the asterisk on the keypad to silence the alarm. Note: This only silences the alarm, it does not
clear the MOB from the database.
If more than one transmitter has been activated, the LCD will display each
transmitter in sequence as the respective signals are received.
When the receiver is turned on a pattern of asterisks should flash across the top
of the LCD indicating that the system is functioning properly. If this pattern
stops or fails to appear the receiver will not receive alarms. The receiver
should be reset for 5 seconds and then turned on. If the test pattern appears indicating normal operations then no further servicing is required. If the test pattern fails to appear and move from left to right then the unit is broken and
should be returned to the manufacturer for servicing.
To register a transmitter as belonging to ownship
Resetting the Receiver
Press the A button on the receiver keypad. The LCD should change to display
“Activate the ORCA to be registered.” Follow the on screen instructions, activate the transmitter and as soon as the transmitter is identified by the receiver,
the receiver will display “If ID number is correct press A.” NOTE: the ID
number is the same as the transmitter serial number, this number can be found
in two places. One label with the serial number is on the back of the transmitter unit, the other label is located inside the battery compartment. If the ID
number displayed on the receiver is not correct, press the B button on the keypad and restart the process. Once the unit is registered the transmitter should
be turned off. To exit setup mode press the D button on the keypad.
To delete transmitter(s) from the ownship list
To reset the receiver, push switch to the OFF position, wait 5 seconds and
then push it back to the ON position. Once the receiver has been reset, it
will continue to receive MOB transmissions from ORCA if the individual transmitters have not been reset to the armed mode. Note: A receiver
reset will not clear the MOB data currently in the database.
When an individual ORCA transmitter is reset, the receiver’s LCD will
display “ALARM RESET”. This only removes that transmitter’s ID from
the receiver’s system. The identification numbers of all other active
ORCAs will remain displayed on the receiver’s LCD.
To delete one or more selected transmitters from the ownship list, press the B
button on the receiver keypad. The LCD should change to display “Activate
the ORCA to be Unregistered.” Follow the on screen instructions, activate the
transmitter and as soon as the transmitter is identified by the receiver, the receiver will display “If ID number is correct press A” NOTE: the ID number is
the same as the transmitter serial number, this number can be found in two
places. One label with the serial number is on the back of the transmitter unit,
the other label is located inside the battery compartment. If the ID number
displayed on the receiver is not correct, press the B button on the keypad and
restart the process. Once the unit is unregistered the transmitter should be
turned off. To exit setup mode press the D button on the keypad.
To clear MOB from the ownship list
To clear the receiver of all MOB ownship contacts, press the C “Clear MOB
List.” NOTE: The MOB list cannot be deleted by cycling power to the receiver. It must be cleared by this procedure. It is meant to force attention to
the registerred man over board alarm. If power is recycled, an uncleared
MOB’s will reactivate the alarm.
