Intelligent Flameproof IR³ Flame Detector

Product code: 55000-021APO

55000-021APO - Intelligent Flameproof IR³ Flame Detector
The Intelligent Flameproof IR3 Flame Detector is designed to protect areas where open flaming fires may be expected. It is sensitive to low frequency, flickering infra-red radiation emitted by flames during combustion.
Full Details
Electrical Description

The Intelligent Flameproof IR3 Flame Detector is loop powered and needs no external supply. A remote LED alarm indicator may be connected to the flame detector.

Operation

The IR3 Flame Detector is sensitive to low-frequency, flickering infra-red radiation emitted by flames during combustion. Since it responds to flickering radiation the IR3 Flame Detector can operate even if the lens is contaminated by a layer of oil, dust, water-vapour or ice. The IR3 Flame Detector is set to respond to low-frequency radiation at 1 to 15Hz (1 to 2.7μm) in order to detect all flickering flames, including those invisible to the naked eye, eg, those emitted by hydrogen fires. The IR3 Flame Detector has three IR sensors that respond to different IR wavelengths in order to discriminate between flames and spurious sources of radiation. False alarms due to such factors as flickering lighting are avoided by a combination of filters and signal processing techniques.

Application

Flame detectors are used when detection is required to be unaffected by convection currents, draughts or wind; tolerant of fumes, vapours, steam, dust and mist; responsive to a flame more than 25m away and fast reacting.

Device Addressing

Before installing the flame detector, it is necessary to set the address using the DIL switch, which is accessed by removing the front cover, using a 5mm hexagonal key. 7 segments of the switch are set to 0 or 1, using a small screwdriver or similar tool. A complete list of address settings is shown in the Installation Guide (PP2271).

Backward Compatibility

The Intelligent Flameproof IR3 Flame Detector operates only with control equipment using the Apollo XP95 or Discovery digital protocol (or any development of it).

Maintenance & Service

The flame detector is designed to give years of trouble-free operation with minimal attention. However the periodic maintenance steps listed below are essential to maintain reliable fire protection. 1. Inform all appropriate personnel of intention to work on the flame detector. 2. Disable any automatic systems that may be activated by the flame detector if not required as part of the maintenance check. 3. Check that the flame detector’s control panel is functioning correctly and shows no faults. 4. Inspect the detector viewing window for any build-up of dust or other contaminants on the optical surface. If necessary clean the optical surface with a cotton wipe wet with commercial liquid glass cleaner. Rinse with clean water and dry with a clean cloth. The detector specification for performance is with a clean optical sensor window. Contaminants like dust, oil and paint will reduce sensitivity. 5. Ensure the detector still has a clear line of sight of the area it is protecting and no obstacles obstruct its view. 6. Check that the detector is securely fitted. 7. Visually check the exterior of the detector for any mechanical or corrosive damage. 8. Test the operation of the detector with either a portable flame sensor test unit or if practical a flickering yellow flame. 9. Reinstate any automatic system disabled during maintenance. 10. Inform all appropriate personnel on completion of the maintenance work and if necessary record this work.
