3. Configure the SIM100 switch channel mode (indicated as “Channel #xMode”) to the “End of Line Resistor” setting. Please
refer to the SIM100 User’s Manual for details.
4. Mount the Orbis Marine Smoke/Heat Detector and the Klaxon Sounder to their respective bases.
5. Supply power to the NMEA 2000®network and to the SH-003-Kit and verify that the switch channel indicates an “off”
(normal) state using a Maretron display, N2KAnalyzer, or other product capable of displaying switch indicator state.
6. Perform a smoke test and heat test on the Orbis Marine Smoke/Heat Detector and verify that the switch channel indicates
an “on” (alarm) state and that the sounder generates the alarm sound during each of the tests.
7. Disconnect either of the two alarm wires from the SIM100 and verify that the switch channel indicates an “error” state.
8. Reconnect the alarm wires to the SIM100 and verify that the switch channel indicates an “off” (normal) state.
