Siren Marine Wired Canvas Snap Cover Sensor

The Siren Marine Wired Canvas Snap Cover Sensor replaces a standard canvas snap to add perimeter security to boat covers and canvas enclosures. Designed for marine vessel owners who demand reliable entry detection, this sensor triggers silent alerts when canvas coverage is disturbed, allowing boat owners to monitor their investment remotely. Built for the harsh saltwater environment and compact boat spaces, it transforms a passive canvas snap into an active security component without requiring visible wiring modifications.

This wired sensor operates on a normally closed circuit design—when the canvas snap opens, the circuit breaks and transmits an entry alert to the boat owner's monitoring system. The snap-integrated form factor maintains the original function of the canvas fastener while housing the sensor element internally, eliminating the need for separate contact pads or visible magnetic switches. Constructed to withstand marine corrosion and UV exposure, the unit measures a compact 3 x 1 x 3 inches, allowing seamless integration into existing canvas snap hardware with minimal weight addition at only 0.1 lbs.

Marine security professionals and recreational boat owners benefit most from this sensor when protecting unattended vessels in high-traffic marinas or overnight anchorages. Installation requires basic wiring knowledge to connect the sensor to a compatible Siren Marine alarm control panel; the snap replaces existing canvas fasteners without structural modifications to covers or bimini tops. Compatible with most standard canvas snap sizes and boat cover systems, this sensor is ideal for multi-zone perimeter protection when deployed across multiple snap points on cabin enclosures, canvas covers, or canvas doors.
