Maretron's Switch Indicator Module monitors switch closure devices including but not limited to safety equipment (e.g. heat smoke carbon monoxide explosive vapor detectors) security systems (e.g. motion vibration glass break door and port hole magnetic switches) and vessel monitoring equipment (e.g. valve closed/open high water bilge). The power monitor continually monitors these switch closure devices and broadcasts information over the NMEA 2000® network about the switch state so the crew can be alerted to potential conditions or problems that warrant further investigation. Advanced features of the power monitor include the ability to detect whether or not power has been disconnected from the monitored device or if the signal wires have been disconnected due to either corrosion tampering or for any other reason (if the monitored device is so equipped). With the power monitor you can rest assured that critical sensors are receiving power signal wires are connected and all the safety security and vessel functions are under constant supervision. Best of all the power monitor is NMEA 2000® certified so you can view any and all switch indicator status anywhere on the vessel using a compatible NMEA 2000® display. The power monitor is a key component of Maretron's N2KView® vessel monitoring and control system.
