Installation & Maintenance Instructions

Product Usage Instructions

Begin by connecting the power connection pigtail leads of the End Of Line Relay. Connect the Red (Positive Supply) lead to the alarm contact terminal (2) + OUT, and the Black (Negative Supply) lead to the alarm contact terminal (3) – IN/OUT. Refer to Figure 1 for visual guidance.
Next, connect the SH-004 two alarm contact terminals (marked (4) A and (5) A) to a free switch channel on the SIM100. Then, connect the purple/violet pigtail leads of the End Of Line Relay to the same terminals. Figure 1 provides an example of connecting the SH-004 smoke/heat detector to SIM100 switch channel 1 (SW1A and SW1B) and the relay connections to the End Of Line Relay.
Using a Maretron DSM Series display (firmware 1.3.5 or higher) or a Maretron USB100 and PC running N2KAnalyzer software, configure the SIM100 switch channel mode to the End of Line Resistor setting. In this example, set Channel #1 Mode to End of Line Resistor.
Perform a smoke test and heat test on the SH-004 Kit. Verify that the switch channel indicates an on (alarm) state during each of the tests.
To check the error state, remove power from the SH-004 Kit and verify that the switch channel indicates an error state.
Reconnect power and ensure that the switch channel indicates an off (normal) state.
To further test, disconnect either of the two alarm wires from the SIM100 and verify that the switch channel indicates an error state.
Reconnect the alarm wires to the SIM100 and verify that the switch channel indicates an off (normal) state.

WARNING: The SH-004 Kit is shipped with an 8K resistor installed in-line with the End of Line Relay contacts. Do not remove this resistor as it is required for proper operation.

NOTICE: The SH-004 Kit comes with the original manufacturer’s Installation & Maintenance Instructions. Please retain these documents and review them for testing and maintenance procedures to be performed on the smoke/heat detector and End of Line Relay.

General Information

The SH-004 kit is designed for general use smoke detection and not for use in areas where steam and moisture could be abundantly present. For high moisture areas, the Maretron SH-005 kit is ideal. This kit contains a smoke detector and its mounting base and all original manufacturers installation and warranty information papers. Please retain the provided papers for additional reference such as maintenance frequency instructions. This kit also comes with an 8K Ohm EOL (End of Line) Resistor pre-installed to an EOL Relay necessary for circuit monitoring also known as ‘circuit supervision’.

Installation Guidelines

Install SH-004 Kit in accordance with ABYC and NFPA guidelines for fire and smoke detection based on your application.
Never exceed 900 sq. ft. of area for any single detector’s range.
SH-004 Kit can be ceiling or wall mounted directly or fastened to various sizes standard electrical boxes.
Pre-Mount and wire the SH-004 Kit base before installing the head (detector unit).
The SH-004 base features a tamper lock. To enable tamper lock (locking head), cut off plastic tab labeled ‘Snip Off for Tamper Lock’. Twist head (detector unit) onto base in a clockwise motion. To remove, press release tab on base and twist head in a counterclockwise motion
Wire SH-004 Kit in accordance with ABYC or NEC guidelines to select correct wire size (22-16 AWG) and any other applicable wiring guidelines based on your application type.
The application of dielectric grease on the detector base connections is recommended.
Do not mix high current harnessing with fire detection harnessing. For best wiring choice, choose a marine grade, tinned copper, 16 AWG twisted pair cable.
The SH-004 Kit comes with a pre-installed dust cover. Maintain cover affixed to detector throughout vessel construction or until first use.

Wiring & Programming Instructions
Please follow these instructions to connect the SH-004 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 of the SIM100, but connections to other channels are similar.

Connect the SH-004 Kit power terminals (marked as (1) + IN and (3) – IN/OUT) to a 10 – 35 VDC supply that is independent of the NMEA 2000® network power supply as shown in Figure 1. Do not apply power until all connections are completed. Powering the unit separately from the NMEA 2000® network allows the detector to work even when the NMEA 2000® network is powered off.
Connect the power connection pig tail leads of the End Of Line Relay, Red (Positive Supply) to the alarm contact terminal (2) + OUT, Black (Negative Supply) to the alarm contact terminal (3) – IN/OUT as shown in Figure 1.
Connect the SH-004 two alarm contact terminals (marked (4) A and (5) A) to a free switch channel on the SIM100, followed by connecting the purple/violet pig tail leads of the End Of Line Relay to the same terminals. The example in Figure 1 shows the SH-004 smoke/heat detector connected to the SIM100 switch channel 1, terminals (marked SW1A and SW1B) and the relay connections to the End Of Line Relay.
Use a Maretron DSM Series display (firmware 1.3.5 or higher), or a Maretron USB100 and PC running N2KAnalyzer software to configure the SIM100 switch channel mode (indicated as “Channel #x Mode”) to the
“End of Line Resistor” setting. For this example, you would set “Channel #1 Mode” to “End of Line Resistor”.
Supply Power to the NMEA 2000® network and to the SH-004 Kit, verify that the switch channel indicates an “off” (normal) state using a Maretron display, N2KAnalyzer, or a product capable of displaying switch indicator state.
Perform a smoke test and heat test on the SH-004 Kit and verify that the switch channel indicates an “on” (alarm) state during each of the tests.
Remove power from the SH-004 Kit and verify that the switch channel indicates an “error” state.
Reconnect power and verify that the switch channel indicates an “off” (normal) state.
Disconnect either of the two alarm wires from the SIM100, verify that the switch channel indicates an “error” state.
Reconnect the alarm wires to the SIM100 and verify that the switch channel indicates an “off” (normal) state.

WARNING: The SH-004 Kit is shipped with an 8KΩ resistor installed in-line with the End of Line Relay contacts, covered with a heat shrink. Do not remove the resistor as it is required for proper operation.
NOTICE: The SH-004 Kit is packaged with the original manufacturer’s Installation & Maintenance Instructions. Please retain these documents and review for testing and maintenance procedures to be performed on the smoke/heat detector and End of Line Relay.
