The 240VAC Shore Power Relay is used to detect presence and loss of AC shore power. The relay is meant to be hardwired directly to your AC distribution panel. This relay is the hard wired alternative to the Siren Marine Shore Power Sensor Plug for boats with 240VAC systems. Part Number:  SM-ACC-ACRE-240

The Shore Power Sensor Plug allows boaters to monitor system-critical shore power from anywhere. Receive an alert in the event that shore power is lost and avoid costly system shutdown. The Shore power sensor plug is ideal for larger vessels relying on external power sources to run critical systems while on the dock. Part Number:  SM-ACC-SHOR

A magnetic reed switch is used to report unauthorized entry into a main cabin through a door or external hatch. Magnetic reed switches can be connected in series to monitor multiple entry points, providing secure protection against theft. In the event of unauthorized entry, the switches will trigger an entry alert to the boat owner, and can also be configured to sound an audible alarm on the boat. Part Number:  SM-ACC-REED

The Visonic 360 Ceiling Dualtech motion sensor offers robust protection against theft. Simply mount this sensor in a cabin or above the main entryway, and receive notification in the event of unauthorized entry. The sensor can also be programmed to sound an audible alarm.  Featuring a sleek, compact, and elegant design, the sensor blends seamlessly into any décor.  Part Number:  SM-ACC-INFR

The Siren Marine audible alarm produces a powerful beeping sound (105 decibels). The alarm can be connected to one of the outputs on the MTC, which will allow it to be turned on and off from the "switching" section of the Siren Marine App. It can also be mapped to specific inputs (such as a motion sensor) in the app and programmed to turn on automatically.

Optimize GPS tracking of your boat with the External GPS Antenna. When you remotely mount the External GPS Antenna, the Siren 3 Pro will override the use of the internal GPS antenna
