1 Introduction
Congratulations on your purchase of the Maretron Switch Indicator Module. Maretron has
designed and built your SIM100 to the highest standards for years of dependable and accurate
service.
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 SIM100
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 SIM100 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 SIM100, 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.
The Maretron SIM100 is designed to operate within the harsh demands of the marine
environment. However, no piece of marine electronic equipment can function properly unless
installed, configured, and maintained in the correct manner. Please read carefully and follow
these instructions for installation, configuration, and usage of the Maretron SIM100 in order to
ensure optimal performance.
