    1 Introduction The Fire Sentry FSCHCOM-SS4 module is a piggy-back device that allows SS4-series flame detectors to communicate with a HART D105 LED RSW100 D103 LED Network Master. The HART module D104 LED may be considered to be a protocol D102 LED converter.

  • Page 5: Supported Hart Commands

    3 Supported HART Commands The SS4-A HART module supports the commands enumerated below. 3.1 Command 0 Use command 0 to read Unique Identifier. Response to command 0: Manufacturer ID: Hex 6042 String FSCHCOM Product ID: Hex E180 Polling address is assigned by rotary switch RSW100 ( 0 , 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F).

    3.5 Command 6 Use command 6 to write the polling address and loop current mode to the field device. Every HART device must have a polling address. Response to command 6: Byte Format Description Unsigned 8 Polling address Code 0 = loop current off, 1 loop current on. Loop current of this FSCHCOM is enable/disable by hardware dip switches S1.

  • Page 12: Led Indication

    4 LED Indication Four LEDs are provided on the HART module for status indication, as follows: D105 Yellow LED indicates fault or normal. Yellow on = Fault, Off=Normal. D102 Green LED. Solid Green = Hart is polled and response. Off = not active. D103 Green LED.

  • Page 13: Hart Module Connections

    7 HART Module Connections Follow the steps below to connect a single HART module to a HART Master. 1. Turn off power to the detector. 2. Connect HART signaling line to J102 pins #2 and #3. 3. If you need current-source signaling in addition to HART, turn on both S100 switches by pressing them down (toward the circuit board).
