Wired Sensors

AC Shore Power Relay 120 or 240V AC
The AC 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 Plug Sensor. Many customers with 240VAC use this relay to monitor one leg of the 240VAC shore power hookup to detect the presence or loss of dockside shore power.
• Dimensions: 1.5x0.75x1.19in (box) 11.3in (wire)
• Relay may be energized by one of three input voltages: 24VDC, 24VAC, or 120VAC. 240 VAC can be monitored by installing on one leg of the dockside shore power supply line.
• Input voltages are polarity-sensitive and diode-protected.
• Relay contains a red LED which indicates when the relay coil is energized.
• We strongly recommend that a certified marine electrician be hired for any VAC installations or maintenance.

DC Accessory Relay
The Siren Marine DC Accessory Relay allows users to control any 12v onboard devices, such as A/C, deck or spreader lights, sirens, or strobe lights.
• Dimensions: 1.5x0.75x1.19in (box) 11.3in (wire)
• Relay may be energized across a wide voltage range from 9VDC to 32VDC.
• Ideal for 12VDC and 24VDC circuits.
• 15mA operating current is constant across the operating range.
• Input voltages are polarity-sensitive and diode-protected.
• Relay is required to power or switch 12v systems that draw more then 1Amp via the internal outputs of the MTC.

Magnetic Reed Switch
Magnetic reed switches are used to report unauthorized entry into a main cabin through a door or external hatch. 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.
• Dimensions: 1x1in (2-part body, 0.5x1in each) 12in (wire)
• Screw mount and adhesive mount included
• Grounds directly to security input

Shore Power Sensor Plug
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.
• Dimensions: 3ft (wire) 2.5x1.5in (body)
• Standard AC to DC adapter, 3V DC output
• Plugs into AC outlet

Canvas Snap Sensor
The canvas snap sensor is ideal for boats that have a canvas cover or part cover, and replaces a canvas snap for entry alert. When the normally closed alarm circuit is opened, it triggers an entry alert to the boat owner and can also be rigged to sound an audible alarm. A snap cover sensor is a perfect solution for stopping unwanted access to the boat and expensive parts.
• Dimensions: 1.25in (body) 12in (wire)
• Bronze snap body
• Includes 1 magnet for existing canvas snap
• Grounds directly to security input

Mini Audible Alarm
The Siren Marine mini audible alarm produces a powerful sweeping siren sound. The alarm can be connected to one of the outputs on the Main Device, which will allow it to be turned on and off from the "switching" section of the Siren Connected Boat App. It can also sync to specific inputs in the Siren Connected Boat App.
