In simple terms the ISM detects movement (from both engine vibration and acceleration) when attached to the vehicle chassis or body. Once the input voltage is within operating range this movement will provide a trigger signal to the DCC Pro and initiate the charging cycle.
This enables the DCC Pro to be operated in Ignition Mode without having to tap into the vehicle manufacturer’s wiring system to obtain a signal. As a result, the whole DCC Pro install becomes totally independent of the vehicle’s electrical system, aside from the common connection of the main battery terminals.
The ISM incorporates a short wiring harness (tail) which connects directly to the DCC Pro without any changes to the installation (if retrofitting) or any modification to the existing wiring harness.
The ISM is an over-moulded device rated to IP67 (dust and water proof) and can be fastened with the high-quality 3M tape included or via a single screw. Single screw fastening is recommended where vibration is minimal.
The compact size of the ISM allows it to be installed almost anywhere, within reach of the DCC Charging Device, of course. It is not recommended to extend the wiring harness but if Voltage Drop is factored in, it can be undertaken.
The ISM has a single LED indicator which will blink every 8 seconds in standby mode. Once activated by movement the LED will illuminate continuously until such time as the vibration/acceleration is no longer detected and the Voltage drops below the factory parameters.
