    1. INTRODUCTION 1.1 Scope The Fire Sentry FS24X Flame Detector with HART® complies with HART® Protocol Revision 7.0. This document specifies device features and HART® protocol implementation details. The functionality of this Field Device is described sufficiently to allow its proper application in a process and its complete support in HART-capable Host Applications.

  • Page 5: Device Identification

    The FS24X is designed to detect fire in a hazardous area. This device should be mounted so as to avoid areas that contain non-fire radiant energy sources (such as radiant heaters, high intensity lamps, etc.) in close proximity to the detector’s field of view.

  • Page 6: Local Interfaces, Jumpers And Switches

    The indication of a detected malfunction is shown by reducing the loop current output to 1 mA. The FS24X Flame Detector uses three (3) separate, bright LED’s to indicate the Detector’s status. The Blue or Green LED blinks (flashes) once every ten (10) seconds to indicate a Normal, safe operational condition (i.e.

  • Page 7: Connection Summary

    Honeywell Analytics Fire Sentry Corporation 6349-001 There are no jumpers or switches on the HART® module. Refer to the FS24X Installation Manual for information relating to switch selections on the detector.Write Protection Not Supported. 4.3.3 Connection Summary The diagrams below provide connection detail. The first shows how the FS24X Flame Detector plus the HART module connect to the outside world.

  • Page 13: Self-Test

    6349-001 12.3 Self-Test The FS24X executes a self-test sequence every three seconds. All optical sensor channels and the related processing of sensor data are evaluated to ensure that analog circuits, processors, and memory are functional. Depending on the particular function, tests are repeated a number of times to confirm device status prior to declaring a fault.

  • Page 14: Busy And Delayed-Response

    Honeywell Analytics Fire Sentry Corporation 6349-001 12.5 Busy and Delayed-Response The transmitter may respond with "busy" status if a further command is received while self- test is underway. Delayed-response is not used. 12.6 Long Messages The largest data field used is in the response to Command 21: 34 bytes including the two status bytes.
