Before attempting to connect the SIM100 to the AC source, determine the type of system you will be monitoring. The SIM100 supports the connection and monitoring of two different system types; 1) switch with end-of-line resistor (Section 2.4.2.1), or 2) switch without end-of-line resistor (Section 2.4.2.2). To connect Maretron SIM100 accessories, please refer to the installation directions that accompany each accessory.
