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.
1.2 Purpose
This specification is designed to complement other documentation (e.g., the FS24X Installation Guide and Operating Manual) by providing a complete, unambiguous description of this Field Device from a HART communication perspective.
1.3 Who should use this document?
The specification is designed to be a technical reference for HART®-capable host application developers, system integrators, and knowledgeable end-users. It also provides functional specifications used during Field Device development, maintenance, and testing. This document assumes the reader is familiar with HART® Protocol requirements and terminology.

DEVICE IDENTIFICATION

The FS24X HART® module is identified by a serial number that begins with “24X-“. This serial number will be visible on the module circuit card, along with a bar code containing the same information.
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 eaters, high-intensity lamps, etc.) in close proximity to the detector’s field of view. FS24X detectors should be mounted so that they look downward with a minimum twenty degrees (20°) angle. Avoid mounting the detectors in areas where temperatures are outside the specified operating temperature range (-40°C to +85°C). Refer to the FS24X  manual (SECTION 2: INSTALLATION) for mounting instructions.

PRODUCT OVERVIEW

The FS24X is a Multi-Spectrum Flame Detector. A HART® communication module is required for HART® communication.

PRODUCT INTERFACES

4.1 Process Interface
4.1.1 Sensor Input Channels
Fire Sentry multi-spectrum and multi-spectral infrared Flame Detectors are sophisticated, state of the art, electro-optical digital radiant energy transducers that sense Wideband   Infrared radiant the energy emitted by fire’s combustion processes that include molecular emissions and hot particulate blackbody emissions. Additionally, the FS24X  Detectors sense the specific WideBand 4.3 IR “Triple IR” region from approximately 3 to 5 microns. FS24X Detectors also utilize additional spectral regions, the Visible Band and Near Band Infrared wavelengths, to aid in discrimination against non-fire false alarm sources.

4.2 Host interface
4.2.1 Analog Output 1: Loop Current
Loop current is the only output from this transmitter, representing the presence of flame in the range of the instrument, as well as fault status. This output corresponds to the  Primary Variable. Refer to section 4.3.3 for connection details.

• 4.3 Local Interfaces, Jumpers, and Switches
  4.3.1 Local Controls and Displays
  This device has no external local controls.
  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 LEDs 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. no Faults and no Alarms). The Blue or Green LED is OFF when no external 24 VDC input power is applied to the Detector. the Red LED turns ON when a fire is detected. The Yellow LED blinks (flashes) when the window lens is dirty. The dirty-lens condition also results in a loop current of 2 ma.  For all other Fault conditions, the Yellow LED will turn ON.

4.3.2 Internal Jumpers And Switches
There are no jumpers or switches on the HART® module. Refer to the FS24X Installation Manual for information relating to switching 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 connects to the outside world. The second diagram shows how the detector and the module mate together.

 

CAUTION
RISK OF PRODUCT DAMAGE

• Follow static protection procedures while handling the connectors and the wiring of the Module puck to the detector.
•  Use a wrist strap connected to the earth’s ground.

DEVICE VARIABLES

This Field Device does not expose any Device Variables.

DYNAMIC VARIABLES

Only one Dynamic Variable is implemented.

  STATUS INFORMATION

7.1 Device Status
Bit 7 (“Device Malfunction”) is set whenever the device reports any fault. Refer to the user manual for a description of fault conditions.
Bit 5 (“Cold start”) is set whenever the device resets or first powers up.
Bit 4 (“More Status Available”) is set whenever any failure is detected or changes in operating mode. Command #48 gives further detail. (See section 7.3.)
Bit 3 (“Analog channel fixed”) is set whenever the device into forced current or inhibitor multi-drop.
7.2 Extended Device Status
The Field Device cannot predict, in advance, when the maintenance will be required. “Device Variable Alert” is set when the PV is not indicating normal conditions, i.e. when an instrument detects the presence of a flame.

7.3 Additional Device Status (Command #48)
Command #48 returns nine bytes of data, with status information available in bytes #6 and #8, as indicated in the following table:

“Not used” bits are always set to 0. In each case, bit #0 is the low-order bit.

UNIVERSAL COMMANDS

Command #3 returns PV, units, and Loop Current. The first (PV) and the last (Loop Current) variables are the same.
Command #14 contains the serial number of the device (3 bytes), followed by measurement units (1 byte) and 3 floating-point variables for max, min, and span loop current in mA.

COMMON-PRACTICE COMMANDS

9.1 Supported Commands
The following common-practice commands are implemented:

38 Reset “Configuration Changed” Flag
48 Read Additional Device Status
Command #48 returns 2 bytes of data.
9.2 Burst Mode
This Field Device does not support Burst Mode.
9.3 Catch Device Variable
This Field Device does not support the Catch Device Variable.

DEVICE-SPECIFIC COMMANDS

The Field Device does not support any device-specific commands.

11.2 Loop Current Operating Modes

PERFORMANCE

12.1 Sampling Rates
Typical sampling rates are shown in the following table.

12.2 Power-Up
During power-up initialization, the device will not respond to HART® commands, and the analog output is set at 4.0mA.

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. In the case of the optical self-test, which evaluates the optical system by flashing an IR LED and monitoring the reflection from the housing grill, a fault is not declared until a total of  180 consecutive test attempts have failed. This takes a total of nine minutes to complete. Additional self-tests are conducted on a continuing basis to ensure the continuity of relay coils.

The the following power-up or reset, the analog output is set to 4.0mA and the device will not respond to HART® commands. During the self-test, the analog output is held at its last value, and the device may respond normally to HART® commands. Continuous self-testing is part of the normal device operation.
12.4 Command Response Times
Approximate command response times are listed in the following table:

12.5 Busy and Delayed-Response
The transmitter may respond with a “busy” status if a further command is received while self-the-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.
12.7 Non-Volatile Memory
EEPROM is used to hold the device’s configuration parameters. New data is written to this memory immediately on execution of a write command.
12.8 Modes
Fixed current mode is implemented, using Loop current mode (Enable – Point to Point /Disable- Multi-drop). This mode is not cleared by a power loss or reset.
12.9 Write Protection
Write-protection is not supported.
12.10 Damping
User controllable Damping is not supported.
