Installation Instructions
6.1
Scope
The SharpEye Model 20/20MI is a self-contained optical flame detector
designed to operate as a stand-alone unit directly connected to alarm
systems or automatic fire extinguishing systems. The detector can be a part
of a more complex system where many detectors and other devices are
integrated through a common control unit. This chapter does not attempt to
cover all the standard practices and codes of installation. Rather, it
emphasizes specific points of consideration and provides some general rules
for qualified personnel. Wherever applicable, special safety precautions are
stressed.
6.2
General Considerations
Important:
The detector should be aimed toward the center
of the detection zone and have a completely unobstructed
view of the protected area. Whenever possible, the detector
face should be tilted down at a slight angle to prevent the
accumulation of dust and dirt. Do not start an installation
unless all conceivable considerations regarding detector
location have been taken into account.
To ensure optimal performance and an efficient installation, the following
guidelines should be considered:
•
Sensitivity
To determine the level of sensitivity, the following issues should be
considered:
•
Size of fire at determined distance to be detected
•
Type of flammable materials
•
Spacing and Location
The number of detectors and their locations in the protected area are
affected by:
•
Size of the protected area
•
Sensitivity of the detectors
•
Obstructed lines of sight
•
Cone of view of the detectors
