2. SafeFlame IR3 Introduction

2.1 Overview

SafeFlame is

a IR3 type flame detector that utilizes a combination of 3 sensors. One of

the sensors monitors the spectral band for CO

² emissions. The other two sensors
monitor adjacent spectral bands to reduce radiation interference and reduce false
alarms.

The spectrum for the radiation emitted by a flame measured by the detector is altered
by the distance between the detector and the fire. It can also be influenced by the
concentration of CO

2.1.1 Models and Types

² gas in the atmosphere.

SafeFlame IR3 Aluminum

SF200A

SafeFlame IR3 Stainless Steel Explosion Proof

SF200SX

The SafeFlame IR3 Flame Detector comes in two varieties; standard and explosion
proof. The standard SafeFlame detector is made from aluminum and the explosion
proof SafeFlame detector is made from stainless steel. Their part numbers are notated
below:

SF200A - SafeFlame IR3 Standard

SafeFlame Installation and Operation Manual

(Publication#: MA-SF200OM)

2.2 Principles of Operation

2.2 Principles of Operation

2.2.1 IR3 Flame Detector

SafeFlame’s triple IR (IR3) flame detector compares three specific wavelength bands
within the IR spectral range of a fire and their ratio to each other. This offers fast
response without the fear of typical false alarms. One sensor monitors the 4.4
micrometer range and the other sensors monitor the bands above and below.

This advanced technology allows the detector to distinguish between non-flame IR
sources, and flames that emit hot carbon dioxide in the combustion process (which
have a spectral characteristic peak at 4.4 micrometers). As a result, both detection
range and immunity to false alarms can be significantly increased. The SafeFlame IR3
detectors can detect a 0.1m² (1ft²) gasoline pan fire at up to 65m (215ft) in less than 5
seconds.

SafeFlame’s IR3 detector is designed to ignore constant background IR radiation,
which is present in all environments. Instead it measure the modulated part of the
radiation of a fire.

2.2.2 RS-485 Modbus

The SF200A/SX is capable of connecting to any RS-485 communication network by
connecting to a universal controller. The detector is capable of informing the network of
the current product condition (fire, fault, warning) and can be used in synch with
interlinking remote control.

2.3 Detector Performance Options

2.3.1

Cone of Vision

The SF200A/SX have a field of view of 90° horizontal, 90° vertical.

SafeFlame Installation and Operation Manual

(Publication#: MA-SF200OM)

2.3.2

Detector Sensitivity

The detector has two alarm levels: Warning (Pre-Alarm) and Alarm. The detection
range for the detector is 200 feet (60 meters) for a standard fire. A standard fire is
defined as a 1ft² (0.1m²) n-heptane pan fire.

The Warning level is an alarm verification system. Having this option enabled will delay
the alarm signal by approximately 5 seconds.

2.3.3

Three colored LED indicators are located inside the detector, one LED is adjacent to
each of the IR sensors.

3. Installation

3.1 Guidelines for Installation

For optimal detector performance and protection of the hazard, please consider the
guidelines for installation:

Spacing: The number of flame detectors in the protected area is determined by

the size of the area, the Cone of Vision, obstructions, and sensitivity.

Aiming: The flame detector should be pointed toward the center of the desired

area of protection. Point the detector pointed at a downward angle
to prevent dust and dirt build up if possible.

Sensitivity: Determined by the size of the fire at the required distance and the type

of flammable materials.

Wiring: Use only 12 to 24 AWG shielded wire for all power and networking

cable

Environment: Avoid areas that are outside of the operating range of the detector and

areas that would be prone to false alarms.

3.2 Unpacking the Detector and Necessary Tools

Ground Connection

For proper operation of the detector the SafeFlame must be grounded through a wire to
the chassis. Failure to establish a ground connection can lead to greater susceptibility
of the detector to power surges, electromagnetic interference, and ultimately damage
to the detector.

External Grounding- Connect ground wire to right side of enclosure.

3.4.2 Conduit Installation

1. Use ½” NPT-14 or M20x1.5 conduit connection or suitable explosion-proof gland to
assemble the cable and conduit to the detector

2. When using conduit connection for division installation, conduit seals must be
withing 18 inches (450mm) from the enclosure

3. When using conduit connection for ATEX installation, conduit seals must be placed
at enclosure

4. Install the conduit including drain holes facing downward to avoid water
condensation in the detector

3.5.3 Alarm Delay

The SafeFlame is equipped with an Alarm delay option, which provides programmable
time delays by changing settings. The alarm signal will be activated if the fire still exists
after the programmed delay time. But if the fire disappears within the programmed
delay time, the detector will return to its standby state.

The alarm delay option affects the output relays and the 0-20mA. The LEDs and the
outputs indicate warning levels during the delay time only if the fire doncition exists.

4.2 Safety Handling

Below are a few safety considerations to take into account when the SafeFlame has
power connected.

-Fault Relay signal Open (N.O.: De-Energized)

- All LEDs off

-Fault Relay signal Closed (N.C.: Energized)

- After 7 seconds of self-diagnosis test, LED intersect for
3 seconds (Orange Red Orange etc) blinking→ → →

-All output, “Normal” signal (N.C.: Energized)

- Yellow LED blinking (0.5Hz)

- Fault Relay signal Closed (N.C.: De-Energized)

- LED “Fault” signal output

- 0-20mA “Fault” signal

- RS-485 communication “Fault” signal

Ÿ Please refer to the diagrams and specifications in the user manual
Ÿ Do not open the SafeFlame while the power is connected
Ÿ Disassembly and assembly of the internal electrical parts is not allowed by anyone

except the manufacturer. Unauthorized action will void the warranty

Ÿ Before working on any equipment be sure that the detector is disconnected from

any suppression or extinguishing systems.

4.3 Testing

(Publication#: MA-SF200OM)

4.3.1 Built-in-Test

The detector will automatically perform a self-diagnostic test every 12 hours.

4.3.2 Test Lamp

The TL305 generates specific IR3 radiation which can be detected by the SafeFlame
detector series as a fire. It has an individual built-in internal power supply, making it
portable with up to a 30 minute charge.

Ÿ Testing Procedures with the TL305

1. Please wait for 10 seconds after power is connected. Check if Yellow LED is
blinking

2. Turn on the TL305 and point it at the front of the SafeFlame. The recommended
distance between the test lamp and the detector is within 16ft(5m)

3. If the Red LED is on, the fire is detected

4. If the product is set to reset manually, cycle power to the detector

5. If the Red LED does not turn on, please reduce the testing distance and try
again. If that same problem persists, check the test lamp for functionality. If
working properly, contact the manufacturer.

Note: If bulb No. 1 is blinking and the radiation intensity is weak, or if the No. 2 bulb is

not functioning, please re-charge the test lamp. If neither the No. 1 or No. 2 bulbs
turn on, it means the test lamp is defective and require repair.

5. Maintenance and Troubleshooting

This section deals with preventive maintenance, describes possible faults, and
indicates corrective measures. Ignoring these instructions may cause problems with
the detector and may invalidate the warranty. Whenever a unit requires service, please
contact Safe Fire Detection or its authorized distributor for assistance.

Please record the maintenance process for the detector in the maintenance book.
Device name, date of installation, name or supplier, and other necessary information
must be recorded accordingly. If there is any service needed, the maintenance record
should be sent with the detector for reference.

5.1 Maintenance

The detector must be kept as clean as possible. Clean the viewing window and the
reflector of the SafeFlame periodically. The frequency of cleaning depends on the local
environmental conditions and specific applications. Cleaning and operation testing
must be completed at least every 6 months.

Steps for cleaning the detector:

1. Disconnect power to the detector before proceeding with any maintenance
including window/lens cleaning

2. Use cleaning liquid for view window on detector. Do not forget to rinse when
finished.

3. Where dust, dirt, or moisture accumulate on the window, first clean it with a soft
brush, and use the cleaning liquid with a soft cloth. Finally rinse it clean with water

5.2 Troubleshooting

No LED response after power applied

Yellow LED blinking (2Hz)

Output signals not recieved

1.Check that the detector is connected
properly

2.Check that the detector is connected with
the appropriate power supply polarity

3.Check the voltage supplied to the detector

4. Check to see if there has been an internal
short due to a foreign substance

1.Check the input voltage of the product

2.Check all wiring and search for signs of
for signs of foreign substances

3. If input voltage is correct, please contact
the manufacturer

1.Check that the detector is connected

properly

2.Check that the wiring connections are

correct according to the user manual

3. Fire signals can be measure after

detection. Check if there is a signal after
performing a fire test

4.Check the jumper setting for 0-20mA

current output is correctly set

Any LEDs blinking repeatedly
(1Hz/2Hz) with 1 second delay

1. Contact the manufacturer
