Wireless dead man switch and emergency engine stop alarm system that operates within 2 seconds of the user falling overboard.
Guardian tracks up to 15 OLAS transmitters and covers vessels up to approx. 50ft.
The OLAS app allows advanced setup and can act as an external alarm.
OLAS is scalable and allows cost-effective integration on multiple ships.
What does it do?
The OLAS Guardian gives powerboat and RIB boat operators the confidence that their boat will stop the moment the skipper or crew are separated from the boat, reducing the chances of a serious accident from an unmanned, uncontrolled boat. The crew is free to move around the boat without constantly having to remember to insert a physical deadman switch.
How does it work?
Up to 15 OLAS Transmission Units / Wristbands (OLAS Tag / OLAS Float-On) within range of the Guardian, giving the crew and skipper the freedom to move around the boat with confidence that if someone falls overboard the engine will be cut off and / or an alarm will be given and a quick rescue can be initiated.
The Guardian connects to the 12/24v power supply and the existing dead man's switch using the supplied connectors, making it quick and easy to install.
A 19mm hole is required close to the existing deadman switch for fitting the stainless steel 20mm LED control switch.
Professional installation is not required but recommended as no liability is accepted for incorrect installation.
Who is it for?
OLAS Guardian is intended for motorboat drivers and all skippers and boat owners who are concerned about safety on board. It wirelessly connects up to 15 crew members via portable OLAS transmitters (wrist tags or OLAS Float On Light) and creates a virtual dead man switch
Runs in parallel with the existing dead man switch
The Guardian can be used in place of or alongside an existing kill switch and will work if the physical kill switch is not in use by the driver.
On most engines, a simple parallel connection to the existing dead man switch allows for wireless operation.
Automatic restart
After 5 seconds, the cut-off switch is deactivated so that the engine can be restarted
Built-in alarm
An 85db alarm will sound to indicate that an OLAS transmitter is out of range
Built-in emergency light (if externally mounted)
High power red light will illuminate, providing a clear visual indication of an alarm, while also acting as a light to illuminate the surrounding area
Selection of relay
The OLAS app allows individual relay selection for easy adjustment, so the OLAS transmitter triggers either engine cut-off or only triggers the Guardian's built-in MOB alarm
Automatic connection
When you board your vessel and turn on the power, the Guardian will automatically connect to all powered-on OLAS transmission units within 2 meters.
connection warning and override
If you board the vessel and no transmitters are on, the Guardian will issue a warning. This alarm can be stopped either by connecting the OLAS transmitter to the Guardian, or the Guardian can be turned off manually. The vessel can then be driven as usual using the physical deadman switches.
Pause mode
The system can be put into pause mode. This is used when you need to leave the boat with the engine idling, such as going down the boat bridge.
Connects up to 15 OLAS transmitters (OLAS tags or OLAS Float-On)
Up to 15 transmitters allow larger craft to link crew and objects to the Guardian. You will always be alerted if someone or something is out of reach of the Guardian (e.g. crew, dinghy or lifebuoy).
Extender compatible
An OLAS Extender is available to cover areas where the transmission signal may be blocked. This allows use on larger vessels up to 100 feet and allows the system to be scaled up if needed.
Easy installation:
1. Check with your motor manufacturer if the dead man switch/disconnect switch is operated by closing the circuit or opening it! Most motors operate by closing the circuit to stop the motor.
a. If closing the deadman's switch to cut off the engine, connect the GUARDIAN in parallel with your current deadman's switch.
b. If opening the deadman switch to cut off the engine, connect the GUADIAN in series with your existing deadman switch.
2. There are 3 signal lines:
Gray = COMMON / GROUND
Brown = CLOSED TO STOP
Purple = OPEN TO STOP
3. Connect the gray wire to the dead man switch common / ground wire
4. Connect the brown wire to the remaining wire on the dead man switch if your motor closes/shorts to stop motor.
5. Connect the purple wire to the remaining wire on the deadman switch if your engine opens the circuit to stop engine.
NOTE: ONLY two signal cables must be connected
6. Close the wire that is left over with the supplied end sleeve.
