Maretron SH-449CSTE

The Maretron SH-449CSTE is a smoke/heat detector that can be connected to the NMEA 2000 network via a Maretron SIM100 Switch Indicator Module. It has two alarm contact terminals that can be connected to a free switch channel. The switch channel mode should be set to "End of Line Resistor" for the appropriate channel using a Maretron DSM250 display or other compatible display product. The detector can be powered separately from the NMEA 2000 network, allowing it to work even when the network is powered off. The SH-449CSTE comes with an 8KΩ end-of-line resistor and a jumper wire installed between the supervisory relay and the alarm contacts. These components are required for proper operation and should not be removed.

Installation Instructions
SH-449CSTE Smoke/Heat Detector
Instructions
Please follow these instructions to connect the SH-449CSTE to the NMEA 2000 network via a Maretron SIM100
Switch Indicator Module. The wiring diagram appears in Figure 1 on the reverse side of this page. The diagram
shows a connection to channel #1, but connections to other channels are similar.
1. Connect the SH-449CSTE power terminals to a 8.5-33VDC supply that is independent of the NMEA 2000
network power supply as shown in Figure 1. Powering the unit separately from the NMEA 2000 network
allows the detector to work even when the NMEA 2000 network is powered off.
2. Connect the two alarm contact terminals to a free switch channel. The example in Figure 1 shows the
detector connected to switch channel 1, terminals SW1A and SW1B.
3. Use a Maretron DSM250 display (firmware 1.3.5 or higher), the DSM250 Viewing function of Maretron
N2KAnalyzer software, or other Maretron display product capable of configuring the SIM100 to set the
switch channel mode (indicated as “Channel #x Mode” on the DSM250) for the appropriate channel to the
“End of Line Resistor” setting. For this example, you would set “Channel #1 Mode” to “End of Line
Resistor”.
4. Supply Power to the NMEA 2000 network and to the SH-449CSTE and verify that the switch channel
indicates an “off” (normal) state using Maretron N2KView software, N2KAnalyzer, or other product
capable of displaying switch indicator state.
5. Perform a smoke test and heat test on the SH-449CSTE (or optionally, test the unit by holding a magnet
close to the “TEST” point marked on the outside of the detector) and verify that the switch channel
indicates an “on” (alarm) state during each of the tests.
6. Remove power from the SH-449CSTE and verify that the switch channel indicates an “on” (alarm) state.
7. Reconnect power and verify that the switch channel indicates an “off” (normal) state.
8. Disconnect either of the two alarm wires from the SIM100 and verify that the switch channel indicates an
“error” state.
9. Reconnect the alarm wires to the SIM100 and verify that the switch channel indicates an “off” (normal)
state.
WARNING: The SH-449CSTE is shipped with an 8KΩ end-of-line resistor installed between one of
the alarm contacts terminals and one of the supervisory relay terminals. Also, the detector is
shipped with a jumper wire installed between the supervisor relay and the alarm contacts. Do not
remove either the resistor or the jumper wire, as they are required for proper operation.
