3.0 Installation
WARNING
- Installation and Maintenance must be carried out by suitably skilled and
competent personnel only.
3.1 Upon Receipt of Your Equipment
All items shipped by General Monitors are packed in shock absorbing containers which
affords a considerable degree of protection against physical damage. When received, the
contents should be carefully removed and checked against the enclosed packing slip. All
subsequent correspondence with General Monitors must specify the equipment part
number and serial number.
3.2 Choosing
Detector Locations
Several variables are involved in selecting the locations to install detectors to ensure
proper flame detection. There are no hard and fast rules defining the optimum location.
There are some general suggestions that should be considered in regard to particular
conditions at the site where the unit(s) are being installed:
Detector Field of View
Each Model FL3112 Flame Detector has a 120
°
maximum Cone of Vision. (
This Cone has
its vertex at the center of the detector, see figure 3-A).
Optical Sensitivity Range
The distance at which the detector will respond to a flame is a function of the intensity of
that flame. The maximum distance is 50 feet (15.2m) for a gasoline fire with a surface area
of 1 square foot (0.92m
2
).
1. Environmental Factors
2. Mounting should be as free from shock and vibration as possible and convenient
for visual inspection and cleaning.
3. Detectors mounted in dirty atmospheric conditions will require more frequent
inspection, cleaning, and sensitivity checking.
4. Observe the ambient temperature range for the specific model (
see section 2-4
Environmental Specifications
). For outdoor installations or other areas exposed to
intense, direct solar radiation, the detector may reach temperatures well above
specifications. For this condition, a cover for shade may be required to bring the
detector temperature within specifications. As with any cover or object near by,
make sure the field-of-view of the detector is not obstructed.
5. Avoid conditions of ice build up on the optical detector windows. Complete icing
over of the IR detector window can result in fault conditions.
