Scope

The SharpEye Model 20/20MPI is a self-contained Optical Flame Detector
designed to operate as a standalone 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 of 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

Very 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.
