2. SafeFlame IR3 Introduction
2.1 Overview
SafeFlame is
the sensors monitors the spectral band for CO
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
a IR3 type flame detector that utilizes a combination of 3 sensors. One of
² emissions. The other two sensors
monitor adjacent spectral bands to reduce radiation interference and reduce false
alarms.
² gas in the atmosphere.
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:

2.2 Principles of Operation
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.
2.2.1 IR3 Flame Detector
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.
2.2 Principles of Operation
2.3 Detector Performance Options
2.3.1 Cone of Vision
The SF200A/SX have a field of view of 90° horizontal, 90° vertical.

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.

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
Please inspect the external condition of the detector when unpacking the product. If
there is any damage on the detector please contact the manufacturer immediately.

SafeFlame Installation and Operation Manual
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
3.4.2 Conduit Installation
CONTROLLER
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.

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.
ŸPlease refer to the diagrams and specifications in the user manual
ŸDo not open the SafeFlame while the power is connected
ŸDisassembly and assembly of the internal electrical parts is not allowed by anyone
except the manufacturer. Unauthorized action will void the warranty
