Q. There are only two security inputs on the MTC, how can I use more than two sensors to protect my boat?

All that needs to be done is put two of the sensors into one of the inputs. Please be aware that when an alert is triggered you will not be able to know which one is setting off the alert since there are two sensors in one input.

*Siren Marine Beam Sensors can not be wired in series.  Only one Beam Sensor per security input is supported.
