This clever little pigtail adaptor (shown below) connects a 10m or 20m 'audio' cable to a Sensor-C2 to form an alarm loop that can be used to detect and deter the theft of equipment from inside or outside a remote property monitored by MaxMon.


Plug the pigtail adapter into a Sensor-C2 port. Plug one end of the 10m or 20m 'audio' cables it comes with into one of the other adapter terminations and run the 'audio' cable to the equipment to be monitored (such as an outboard motor to dinghy on the deck of a boat). Loop the cable securely through the item(s) and back to the unused connector on the loop adapter. You should now have a continuous electrical loop that runs through your monitored item(s) in such a way that for someone to steal the item(s) they must break the cable ... which will be detected by the Sensor-C2, which works by detecting OPEN or CLOSED electrical circuits!

Things to consider when installing:

  • If the Sensor-C2 is inside your remote property and the monitored equipment is outside you will need some kind of small opening through which you can easily run (and remove) the loop cable without allowing water ingress.
  • Ideally both ends of the loop cable will be inside your remote property, so a thief is faced by an unbroken loop they cannot easily repair if broken.
  • It's probably best to arrange the loop so it isn't visible. A thief will probably pull on it hard, or cut it, so if you configure a Sensor-C2 alert action that activates a light, strobe or siren that would be a sudden and shocking deterrent.
  • To guard against the Sensor-C2 itself being damaged by a hard pull on the loop cable you should install good stress relief on the loop adapter (i.e. tie it down very firmly).
  • You will need an 'audio' cable at least twice as long as the distance from your Sensor-C2 to the monitored item(s), because the cable is deployed in a loop.
