Flameproof (Exd) UV/IR² Flame Detector

Product code: 55000-065APO

55000-065APO - Flameproof (Exd) UV/IR² Flame Detector
The Flameproof UV/IR2 Flame Detector is designed for hazardous environments in either indoor or outdoor applications where open fires may be expected. False alarms from flickering sunlight, arc welding or lightning are avoided by the combination of UV and dual IR signal processing techniques. It detects almost all flames, including those invisible to the naked eye, e.g. hydrogen fires. Certified by ISSOP for compliance with standards EN50014, EN50018 and EN50281.

Electrical Description

The UV/IR² Flame Detector signals an alarm state by switching an alarm latch on, increasing the current drawn from the supply from 8mA to 28mA and closing the contacts of a Fire relay RL1. These signals from the detector are recognised by the control panel as an alarm signal. The alarm current also illuminates the detector integral red LED. A Fault relay RL2 closes its volt free contacts if the detector has no faults and the supply voltage to the detector is the correct value. To ensure correct operation of the detector the control panel must be arranged to supply a maximum of 30 volts DC and a minimum of 14 volts DC in normal operation. To restore the detector to quiescent condition after indicating a fire, it is necessary to extinguish any flames in view and interrupt the electrical supply to the detector for a minimum of one second. Removing the detector front cover provides access to the detector terminals and configuration DIL switch. The detector is normally configured to latch into an alarm state when a flame is in view. The configuration DIL switch within the detector can be set to place the detector into a non-latching mode. The detector can then also produce proportional analogue current alarm signals i.e. 8-28mA or 4-20mA. In non-latching mode the detector only produces an alarm signal when a flame is in view resetting itself to normal a few seconds after the flame has gone.

Application

Flame detectors are used when detection is required to be unaffected by convection currents, draughts or wind, tolerant of fumes, vapours, responsive to a flame more than 25m away and fast reacting. Typical applications examples are: -engine room -factory -fuel storage and handling -petro-chemicals -printing -warehouse Applications and locations to avoid: -prolonged ambient temperatures above 55°C -lights shining directly onto optics -exposure to severe rain and ice -gathering of dust or oil films on sensor window -flood or spot lighting falling directly on optics -obstructions to field of view

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.
