OLAS TRANSMITTERS
OLAS RECEIVERS
ACR OLAS MOBILE APPLICATION
IMPORTANT INFORMATION
GUARDIAN INSTALLATION
The OLAS TAG or the OLAS FLOAT-ON are considered OLAS transmitters. They emit a Bluetooth signal
which is monitored by the OLAS receivers.
The OLAS receivers track the OLAS transmitters. OLAS receivers are:
1. GUARDIAN - Wireless Engine Kill Switch and Man Overboard (MOB) Alarm System
2. CORE - Base Station for OLAS Transmitters and Man Overboard (MOB) Alarm System
3. OLAS Mobile application
4. EXTENDER - This operates as a repeater to increase the range of the GUARDIAN and CORE
The ACR OLAS mobile application allows the OLAS transmitters to be used as a MOB/proximity alarm if
connected solely with OLAS transmitters. When an OLAS transmitter goes out of range an alarm is set off
and overboard screens are activated.
When the OLAS mobile application is connected to the Guardian or Core it allows greater control over the
OLAS transmitters that are being tracked.
To download the app, enter “ACR OLAS” in the Apple App Store or Google Play
The Guardian has been designed for recreational marine use. The design conforms to appropriate
Electromagnetic Compatibility (EMC) regulations but for optimal performance correct installation is required.
For optimum performance the mobile device and the Guardian should be located at least 0.5 meters from
any equipment transmitting radio signals including VHF Radios, antennas and cables.
WARNING: Do not attempt to install the Guardian until you know that the power supply is switched OFF.
Where required use the supplied wire connectors which are suitable for connecting wire dimension 20-
18AWG. If wire extensions are required use 20AWG or thicker wire.
Always connect your power supply after the main power switch to avoid current drainage when the boat is
not in use.
Ensure all wire connections are waterproof using marine specic connectors, such as heat shrinkable
butt splices.

5
DRILLING THE HOLE
Find a location to install the Guardian’s control switch, either next to or near your existing kill switch, then drill
a 0.8 inch (21mm) diameter hole.
The orientation of the securing nut shown below is dependent on panel thickness:
0.8” diameter hole
0.31”-0.71” (8-18mm) panel thickness
0.04”-0.31” (1-8mm) panel thickness

6
CONNECTING THE POWER WIRES (10-32VDC)
CONNECTING THE SIGNAL WIRES ALONGSIDE YOUR EXISTING KILL SWITCH
Connect power cable to Guardian hub.
Ensure Power supply is switched OFF.
1. Connect the white (+ or positive) wire to the positive voltage terminal
2. Connect the black (- or ground) wire to the negative voltage terminal
3. Install a 1-3 A fuse in line with the positive connection
The Guardian uses a double throw relay enabling it to open or close any circuit. It can be connected in
place or alongside your existing kill switch as it can be installed to perform the same function.
1. Check with your engine manufacturer if the kill switch is operated by Closing the circuit or Opening
the circuit. Most engines operate by closing the circuit to stop the engine.
Close to stop systems should connect in parallel to your existing kill switch.
Open to stop systems should connect in series to your existing kill switch.
2. There are 3 signal wires:
Grey= COMMON
Brown = CLOSE TO STOP
Purple = OPEN TO STOP
3. Connect the grey wire to the existing kill switches common wire
4. Connect the brown wire to the remaining kill switch wire if your system uses the close to stop system
5. Connect the purple wire to the remaining kill switch wire if your system uses the open to stop system
NOTE: ONLY two signal wires should be connected
6. Close off the remaining wire with the supplied end cap
SECURE THE GUARDIAN HUB
1. Find a location where the hub can be securely attached, and the power and switch wires can remain
securely attached to the hub
2. The attachment screws provided are self-tapping for plastic / wood so can be screwed directly into
the center console. Ensure attachment point is thicker than the attachment screws to avoid screwing
through the panel.
3. Secure the hub rmly into the center console

TERMS & CONDITIONS
The OLAS systems are products from Ultimate Sports Engineering Ltd.
OLAS wireless systems utilise OLAS transmitters (OT) and OLAS receivers (OR).
OLAS transmitters consist of the OLAS tag and OLAS Float On.
OLAS receivers include the Guardian, the Core, the Extender and the OLAS mobile application (OLAS app)
Before using any OLAS wireless system it is imperative that you read the DISCLAIMER and the LIMITATION
OF LIABILITY which follows. There is legal presumption that by using OLAS wireless systems you have read,
understood and accepted the DISCLAIMER and the LIMITATION OF LIABILITY statement.
Setup
Start and setup all OLAS systems before you leave the dock and ensure all OTs are connected. Connecting
the OLAS app allows visual indication of connected OTs.
Check the battery level of OLAS tags using the OLAS app. Check the battery level of OLAS Float-On’s using
the inbuilt color coded battery indicator.
The OLAS App
Ensure GPS is running in the background on your mobile device. Keep your mobile device plugged in to a
charger as GPS drains the battery. It is advised that the app is running in the foreground to enable maximum
response time. It can take up to 30 seconds for the system to respond if the phone is in locked mode.
Test the Connection Whilst In Dock
Test the connection between the OR and the OT by leaving the OR in its planned location and walk the OT
to the furthest point on the vessel. Check that all OT’s being used are working correctly by submersing them
in more than 4 inches of open water which will activate the alarm on the receiver.
Advice
As soon as a MOB situation occurs ensure a crew member keeps visual contact and points at the MOB.
Contact the emergency services and give them the co-ordinates from your vessels GPS navigation system
and the time since the MOB occurred.
Use OLAS Systems frequently as a practice aid for a MOB situation.
Disclaimer:
OLAS wireless systems are an aid only and should be used alongside existing safety products and
procedures. They should not be used for navigation or lifesaving procedures. The OLAS app GPS
coordinates cannot be relied upon to be accurate. Whilst accuracy of between 10-30 metres can be
achieved, many factors can cause larger variations. The OLAS app cannot and does not take the external
environment into consideration. Wind, tide, current and other factors will affect the position of the MOB.
The OLAS app can only assist you in getting back to the position that the automatic alert was issued. The
OLAS app is not warranted to be accurate. GPS reception is variable and cannot be relied on. The phone
can take up to 40 seconds to get a good GPS lock even when GPS connectivity is available.
The OLAS app will be more accurate if already running for 1 minute before grabbing the GPS location. It is
advised that the app is running in the foreground to enable maximum response time. It can take up to 30
seconds for the system to respond if the phone is in locked mode. The OLAS App should only be used to
complement other MOB methods and procedures.

Limitation of Liability:
In no event shall Ultimate Sports Engineering Ltd or its members, representatives or suppliers be liable for
any damages whatsoever (including, without limitation, loss of property, personal injury, lost revenue, lost
