Detector Enclosure With Bracket; Sighting Requirements - Dräger Flame 5000 Technical Manual

Detector Enclosure with Bracket

Sighting requirements

Observe the following:
• Ensure the mounting position is free from vibration or movement
• Prevent accidental knocking or forcing out of alignment
• Where snow or ice build-up is likely, the heater should be enabled
• To ensure the best possible video image the detector should be facing away from the sun
• Isolate as far as possible from local electrical interference sources
• Ensure suffi cient detection to achieve adequate coverage for all likely hazards
• Minimise exposure to contamination of the detector face plate
• Ensure ease of maintenance access to detector (i.e. direct, ladder or scaff old access)
All these issues are of crucial importance to a successful installation, and they should be given great attention during
the detailed design, construction, and commissioning phases of the work.
