Need help with your alarm?

Here are answers to the most commonly asked questions about the YachtSafe GPS alarm, accessories, and app.

Can I install the alarm myself?

YachtSafe is the easiest to install GPS alarm available. The alarm is designed for you to be able to easily install it yourself. The small alarm unit has internal antennas and just three connection cables (G31 and G32). What’s more, no SIM card is needed. The alarm is activated using the YachtSafe app or by sending an SMS to the alarm unit.

How are GSM service paid for?

You can buy GSM services by logging in via “Administer Alarm” on our website. This will take you to our web shop where you can choose to pay upon receipt of invoice or by card.

Can I use my own pay-as-you-go SIM card?

The alarm is supplied with an integral SIM card. There are two main reasons for this:

1) The product is designed to offer complete protection against moisture and vibration. The product is fully cast, so there are no openings or connections for moving parts. For this reason, it’s not possible to insert your own SIM card.

2) Pay-as-you-go SIM card solutions are also unreliable. Leading insurance companies, and we the manufacturer, advise against using pay-as-you-go SIM cards. If your account becomes empty or is deactivated, the alarm system won’t work. You must always have enough credit in your account to be able to track an object when you need to.

What can the outlet on the alarm unit be used for?

The outlet can be used as a relay to operate a refrigerator or heater, for example, which you can activate from your mobile. The outlet can also be used for the simple connection of a siren that sounds when, for example, a wireless IR sensor is triggered.

Why isn’t the GSM alarm reachable by the app?

The alarm location probably has poor GSM coverage. See whether you can communicate with the alarm using SMS commands to the alarm’s phone number (e.g. [pin code] GPS, [pin code] status, [pin code] alarm on, [pin code] alarm off). Try moving the alarm to another location as the alarm location may have poor coverage.

Why doesn’t the GSM alarm answer my SMS?

This may be due to several reasons:

1) Check whether the GSM service is active. Log in under “Administer Alarm” on our homepage to check whether GSM services have been deactivated.

2) Double-check that all numbers and e-mail addresses registered in the app are correct.

3) Check that the alarm unit is connected to the operating voltage. Measure the voltage of the alarm if you can.

4) A software update may have failed, causing the alarm to “hang”. This can happen to alarms manufactured before May 2013. Disconnect from the power (12V or 24V) for about five minutes and then reconnect. Let the alarm attempt to update the software for around 30 minutes before sending any new requests to the alarm by SMS or via the app.

Why does the GSM alarm respond to SMS commands but does not respond via the app?

Check the app:

App > App Settings: Enter your phone number.
App > Alarm Profile: Enter the telephone number and pin code of the alarm unit.
All phone numbers must be entered with +46.

Another reason could be that the alarm has been set to power-saving mode. You can use the remote control to switch between two different modes. Power-saving mode can be used during winter storage, for example. This mode completely turns off the GSM unit and only switches on again if an alarm is triggered. This saves battery power as it uses less power.

Change the mode by pressing the “star” button on the remote control for approximately ten seconds until it begins to flash. On older remote controls, the remote control flashes twice (normal mode) or three times (power-saving mode). On newer remote controls, the remote control always flashes twice and an SMS confirmation is sent to any saved alert receivers to notify them of the mode that the alarm unit is in. NOTE! You must be close to the alarm for this to work as the range of the remote control is limited.

Why does the GPS alarm have no GPS position?

The alarm updates its position every ten minutes and will attempt to do this for a limited time in order not to consume too much of the internal battery capacity. If the GPS signal is disturbed by something, such as by being shielded by any metal or by the incorrect orientation of the alarm, the alarm may have difficulty updating its position.

Check the alarm’s orientation and location. Turn the alarm on and wait ten minutes before requesting its position again. The alarm should now find its position, but note that the alarm’s ability to receive GPS signals is reduced when indoors.
