  1. How much current does the Maretron Smoke/Heat Detector (part # SH-002) draw from a power source? The smoke/heat detector requires only 70µA from a power source while standing by and monitoring for smoke or heat. The current requirement increases to 60mA once smoke or heat has been detected and the alarm is sounding. Please note that the smoke/he... Read More
  2. Does the gas detector (Maretron part LP-200012UL) have a power supervision relay? Although some of Maretron's SIM100 accessories have built-in power supervision relays like the smoke/heat detector (Maretron part number SH-002) and carbon monoxide detector (Maretron part number CO-CO1224T), the gas detector does not have a bui...

  3. With regards to the DCM100, where should I connect the ring terminal of temperature sensor (part number TR3K)? You should connect the ring terminal on the Temperature Sensor to the negative terminal of the DC source being monitored.... Read More
  4. What are the dimensions of the Exhaust Gas Temperature (EGT) accessory probe (Maretron part number TP-EGT-1) used with the TMP100? Please see the attached PDF file for the dimension of the EGT probe.... Read More
  5. How do I monitor the bilge with Maretron equipment? Before we discuss how to monitor the bilge with Maretron equipment, let's take a look at a typical bilge pump and alarm wiring diagram (see Figure 1). Notice that there are two ways to turn the bilge pump on. First, there is the float switch -- ... Read More
  6. What is the supplied cable length of the TMP100 sensors; is it possible to extend the cable? Maretron thermistor probes come with 6' long wires. Yes, you can extend Maretron TMP100 sensor wires to complete temperature sensing applications throughout a vessel.In many applications technicians have extended thermistor wires up to 100 feet ...

  7. How do I choose the correct pressure range when specifying a pressure transducer for measuring fluid level in a deisel or water tank? Maretron offers pressure transducers with different pressure ranges. You choose a particular transducer based on the depth of the tank (assuming you install the pressure transducer at the deepest part of the tank, otherwise use the installation depth... Read More
  8. Why does the SSC200 rate of turn indicate that I am turning when I am not turning? The SSC200 rate of turn may indicate that the vessel is turning when the vessel is not turning. You correct this situation by calibrating the rate of turn gyro within the SSC200 using either a DSM200 or a DSM250. To calibrate the rate of turn using o... Read More
  9. How do I calibrate the SSC200 rate of turn using Maretron’s DSM150, DSM200, or DSM250 display? You calibrate the SSC200 rate of turn using a DSM150, DSM200, or DSM250. To calibrate the rate of turn using one of the displays:Enter menu mode, scroll to "Configuration..." and press < Enter >Scroll to "Device Configuration..." and press < Enter >S... Read More
  10. I see the SSC200 uses the NMEA 0183 identifier II (i.e., the two letters following the $ of an NMEA 0183 sentence); is it possible to change the identifier to some other value? Yes, it is possible to change the identifier that the SSC200 transmits as part of NMEA 0183 sentences. Please refer to the user's manual for instructions on how to make this change.... Read More
