SECTION 1: INTRODUCTION

1.1 Description

With the increase in demand for effective, interactive and non-intrusive systems, Net Safety has released

its HART for Flame product providing HART communication with distinct flame detectors. This involves

HART Communication with the Phoenix Triple IR, UV/IR and UV Flame Detectors along with the

Hydrogen Flame Detection line of UV and UV/IR Flame Detectors.

The introduction of HART Communication with flame detectors allows convenient access to the Flame

Detector’s features and provides easy on the spot monitoring. This is important for effective and reliable

maintenance. Access to the HART menu structure and functions of the flame detector is gained by using

the HART Communicator. This may also be done using and any other HART communication devices that

are compatible with the enhanced device description language (EDDL) of Net Safety’s Flame Detectors.

Product components:

This HART for Flame product has two component products; a flame detector with Analog /Analog-

Digital output alongside a HART Communication Output interface. This HART Output circuitry is

enclosed in Net Safety’s Explosion Proof Multipurpose Junction Box and allows users to choose Analog-

Hart or Analog-Hart with Relays outputs. The HART for Flame product is available in Aluminum and

Stainless Steel.

Choice of flame detector:

The model flame detector used with the HART Output interface will depend on users’ choice and nature

of the application. In specific cases users may want to detect hydrogen based fires in which case the

UV/IRS-H2-A/AR or the UVS-H2-A/AR flame detector based HART for Flame product would be

suitable. In other cases users may want to use either the IR3S-A/AD, UV/IRS-A/AR or the UVS-A/AR

flame detector based HART for Flame product to detect Hydrocarbon based fires. Refer to available

models offered below.

Available Model HART for Flame Product (this includes HART Flame Junction Box interface):

UV/IRS-AH/AHR, UVS-AH/AHR, UV/IRS-H2-AH/AHR, UVS-H2-AH/AHR

ATEX models: UV/IRS-AH-X/AHR-X, UVS-AH-X/AHR-X, UV/IRS-H2-AH-X/AHR, UVS-H2-AH-

X/AHR-X

Both CSA/FM and ATEX models are available in Aluminum and Stainless Steel.

Available Model HART Flame Junction Box interface:

JB-MPHF-A (HART output, Aluminum version), JB-MPHF-S (HART output, Stainless Steel version),

JB-MPHFR-A (HART & Relay output, Aluminum version), JB-MPHFR (HART & Relay output,

Stainless Steel version).

System configuration:

After choosing the type of flame detector based on the HART for Flame product, the system should be

configured. This is done via DIP Switch 2 (SW2) located on the HART Flame Junction Box PCB. See

Table 1 when configuring the system.

MAN-0119 Rev 1 HART for Flame Page 5 of 28

1.2 Unpack

Carefully remove all components from the packaging. Check components against the enclosed packing

list and inspect all components for obvious damage such as broken or loose parts. If you find any

components missing or damaged, notify the representative or Net Safety Monitoring immediately.

1.3 Mounting

The HART Flame Junction Box has three ¾ inch-14 NPT conduit entries. The flame detector will be

connected to one of these entries. Connection of conduit and cable glands to remaining conduit entries

should be done so by use of appropriate tools. A 6mm Hex Key is required for installing or removing

conduit entry plugs. The junction box has mounting holes for installing directly on a wall or to a pole as

desired. The junction box is supplied with one ATEX stopping plug.

1.4 Installation Considerations

• Point flame detector toward where the flame is expected.

• Ensure an unobstructed view of the area to be monitored.

• Employ more than one flame detector and HART Flame Junction Box to ensure the hazard is fully

covered.

• Mount the flame detector and HART Flame Junction Box a few feet (about 1 metre) below the ceiling

so the flame detector can respond before being blocked by smoke accumulation at the ceiling.

• If dense smoke is likely to accumulate prior to flame (as in an electrical fire), supplement flame

detector(s) with other protection such as Net Safety Monitoring Airborne Particle Monitor.

• The flame detector should be accessible for cleaning the window and reflector surfaces.

• Tilt the flame detector downward a minimum of 10 to 20

° to reduce dirt and dust accumulation which

could obscure the detector’s viewing window.

• Securely mount the flame detector and HART Flame Junction Box so as to reduce vibration as much

as possible.

• When located outside, the flame detector’s sensitivity can be reduced by heavy fog, rain and/or ice.

• Consider shortening the time delay settings when smoke is expected to accumulate before or during a

fire. See relevant manual.

• Reduce sensitivity setting if false alarms, related to surrounding activities, occur.

• When installed near or on water (such as an off shore platform), be sure to take into account the low

horizon level when tilting detector downward.

For more on installation considerations on flame detectors refer to specific flame detector manual.

1.5 Wiring

Warning Wiring must comply with all applicable regulations relating to the installation of

electrical equipment in a hazardous area and is the responsibility of the installer. Proper shielding and

grounding procedures, for the specific area must be followed. Consult local electrical code and /or

qualified personnel before wiring.

Warning Do not open the HART Flame Junction Box or flame detector in a classified area (Do

not open when an explosive atmosphere may be present). The area should be de-classified prior to

opening.

MAN-0119 Rev 1 HART for Flame Page 6 of 28

1.6 Sealing

Warning To fully avoid any environmental exposure (water ingress), the use of seals is

recommended, especially for installations that use high-pressure or steam cleaning devices in proximity to

the HART Flame Junction Box and flame detector.

It is recommended that explosion-proof drains and conduit breathers be used. Changes in temperature and

barometric pressure can cause 'breathing' which allows moist air to enter conduit. Joints are seldom

enough to prevent 'breathing'.

Consult qualified personnel on sealing requirements relating to equipment, application and local

regulations.

1.7 HART for Flame Dimensional Drawing

The drawing below shows the dimensions of the Aluminum (AL) and Stainless Steel (SS) models of the

flame detector with HART Flame Junction Box enclosure.

Figure 1: Dimensional Drawing (Measurements are in Inches and Millimeters)

Note: CSA/FM model shown

ATEX model has an ATEX locking collar

* M20 & ½” NPT threads also available

SECTION 2: Operation

The model flame detector will determine the model HART for flame unit being used. Specific

combinations of SW2 positions (DIP Switch 2 positions) have been assigned for each available type of

flame detector. Selecting DIP Switch 2 positions correctly will determine the operation of the unit. See

Table 1 and Figure 2 or Figure 3. Once the system has been powered up, confirm operation by referencing

the specific Flame Detector manual. Meter Test Jacks are available on the HART Flame Junction box

PCB to check and monitor the current output (4-20mA). If the HART / Relay model junction box is being

used, note that the relays are dry contacts and are Form C SPDT rated 5 Amperes at 30 VDC/250AC.

MAN-0119 Rev 1 HART for Flame Page 7 of 28

If the HART Communicator is to be placed in the current loop, ensure that the HART Jumper (J5) is in

the factory default position (pins jumpered), then place a 250 Ohm resistor in the current loop and connect

the communicator across the resistor. Refer to Figure 2 or Figure 3 along with Current Loop power block

diagrams and / or Typical Field wiring diagrams. If the HART Communicator is to be used with the

HART Port connector for direct or remote communication, see Section 4.

2.1 Current Loop power configurations

The two current loop power configurations available are the Non –Isolated power configuration and the

Isolated power configuration. When using the Non-Isolated power configuration (Non-Isolated current

loop), the Non –ISO / ISO select jumper (JP1) located on the HART Flame Junction box PCB should

remain in its default position. ‘ISO’ on the power terminal side is not used in this configuration. For the

Isolated power configuration (Isolated current loop), JP1 should be placed over pin 1 and pin 2 and a

separate power supply used to supply +24VDC to ‘ISO’ on the power terminal side. See figure 2 or figure

3 for JP1’s location. Also refer to Current Loop power block diagrams and / or Typical Field wiring

diagrams.

Note: By factory default JP1 (Non –ISO / ISO select jumper) is connected across pin 2 and pin 3 (Non-

Isolated power configuration). Also by factory default the HART Jumper (J5) is connected (pins are

jumpered).

MAN-0119 Rev 1 HART for Flame Page 8 of 28

SECTION 3: Configuring the system

When using the specific model flame detectors (IR3S-AD, UV/IRS-A, UV/IRS-H2-A, UVS-A, UVS-H2-

A, IR3S-A), corresponding SW2 (detector configuration DIP Switch located on HART Flame Jbox PCB)

positions have to be set. The correct combinations of position 1 and position 2 have to be made in order

to have proper operation of the flame detector and HART or HART/Relay model Junction Box. See Table

1 and Figure 2 or Figure 3.

SECTION 4: HART Connection and Communication

4.1 HART Communicator connection

The HART Communicator may be connected to the HART Flame Junction Box via the HART Port

connector. Refer to Figure 4. For remote HART communication, the HART Communicator is connected

to the Junction box interface via a HART Port connector and separation board (JB-MPH-A/S). See Figure

5. Refer to the HART Port connector manual (MAN-0083) and the Net Safety Multi-purpose Junction

Box manual (MAN-0081) during installation.

The HART Communicator may also be placed in the current loop wiring. Refer to Section 4. Place a 250

Ohm load resistor in the 4-20 mA current loop and connect the HART Communicator probes across the

resistor. Do not install a resistor within the HART interface junction box. The total current loop resistance

should be a maximum of 600 Ohms in order to have proper communication with the HART

Communicator.

Figure 4: Direct HART Communication

This drawing is a general representation in connecting the system.

Warning

Built within the HART Port connector are intrinsically safe barrier circuits, which are a

grounded type barrier. The port requires this safe ground to divert the excess energy. The grounding of

the HART Port must meet local safety guidelines

4.2 HART Communication Protocol

The HART protocol incorporates an “Enhanced Device Description Language”, (EDDL) that enables

HART instrument manufacturers to define and document their product in a consistent format. This format

is readable by handheld communicators, PC’s and other process interface devices that support EDDL.

For the Flame Detector- Junction Box Hart interface, handheld HART communicators, PC’s and other

process interface devices must support the latest 16 bits manufacture ID and 16 bits device type. For the

375 model HART Communicator the software version must be at least version 2.0.

Establishing HART Communication with the flame detector and HART Flame Junction Box.

1. Ensure system is wired properly, then power up the unit and ensure no faults are indicated.

2. If the HART Port connector connected to the junction box as an interface, unscrew the HART

Port connector’s protective cap.

3. Connect the HART Communicator non-polarized probes to the 2 non polarized HART Port

connector terminals.

4. If the HART Port connector is not used, ensuring the HART current loop jumper inside the

junction box is in place. Then put the HART communicator probes across a resistor (min. 250

Ohms) within the 4-20 mA loop wiring. The maximum loop resistance of the wiring should be

600 Ohms.

5. Turn on the HART Communicator and proceed to initiate communication. If not familiar with the

communicator, consult the specific HART Communicator manual for operating instructions.

Important Notes:

• Proper analog signal output termination and minimum loop resistance must be completed in

all cases to enable HART communication. Failure to provide proper analog signal output loop

resistance will preclude all HART communication.

• If the HART Communication is not programmed with specific DD or does not support 16 bits

IDs, the JB-MPFH can still connect to the communicator but in the Generic HART

communication mode. In this mode, HART communication with the system will be

established, but the Communicator will not recognize the system (unit). Generic HART

communication will not provide access to the JB-MPHF EDDL menu and important set-up,

diagnostics or operation functions.

If you cannot find Net-Safety or JB-MPHF under Net-Safety on your Communicator, the specific EDDL

is not programmed into communicator. Your HART Communicator will require an EDDL upgrade in

order to access all the JB-MPHF functions.

The HART Communication Foundation, (www.hartcomm.org

), manages the HCF Approved EDDL

Library and programming sites for HCF Approved field communicators. A complete listing of the DD

Library is available for download and provides manufacturer and device type file identification.

SECTION 6: Maintenance

Each type of flame detector performs an automatic visual integrity test on the optics to ensure there is no

obstruction on or near the detectors lens. Though this test is done, it is important to perform routine

maintenance checks and cleaning of the window/lens. It is recommended that cleaning be done with Net

Safety cleaning products. In addition to established maintenance routines, perform response tests on the

detector by using the appropriate Net Safety Test Lamp to simulate fire conditions. Refer to specific

flame detector and test lamp manuals when performing the above checks.

6.1 Troubleshoot

If a problem should develop, Check DIP Switch 2 (SW2) positions to confirm correct configuration, refer

to specific flame detector manual and ensure all wiring is correctly done. If the problem remains refer to

“How to Return Equipment”.Net Safety Flame Detectors and HART Flame Junction boxes are not

designed to be repaired in the field.

Repairs to faulty or damaged equipment should only be performed at

the factory; otherwise warranty on the product will be voided.
