Frequently Bought Together
As part of the Siren Marine MTC system, this magnetic reed switch will remotely alert you to unauthorized entry into your boat's main cabin through a door or external hatch.
The Magnetic Reed Switch can be connected in series to monitor multiple entry points, providing secure protection against theft in combination with the Siren Marine® MTC Boat Monitoring, Tracking and Control Device (sold separately) and the Siren Marine app available for iOS or Android smartphones, tablets and computers. In the event of unauthorized entry, the switches will trigger the Siren Marine MTC unit to send out an entry alert to the boat owner, and can also be configured to simultaneously sound a piercing audible alarm on the boat.
