CHAPTER 4. MICROCELL™ INSTALLATION
ON HORIZONTAL BEAMS
INTRODUCTION
Follow the instructions in this chapter only if
installing Microcells™ on horizontal beams.
This chapter describes the mounting locations,
installation details, and wiring details for
Microcells™ and junction boxes. Follow all
instructions carefully to ensure proper system
operation.
Note
Do not mix different types of Microcells™ on
one vessel. The three types (3” standardized,
3” non-standardized, and 2” standardized) are
not interchangeable.
MOUNTING LOCATIONS
Follow the procedures below to determine and
mark the Microcell™ mounting locations prior to
beginning installation. Following these procedures
will ensure optimal system performance. Consult
Kistler-Morse
® if special considerations prevents
the installation of the Microcells™ at the
designated locations.
MICROCELL™ SETS
See Figure 4-1. Microcells™ are mounted on
beams in a shear mounting set. A Microcell™
is set at a 45° angle to the horizontal with another
Microcell™ set perpendicular to it on the other
side of the support beam. Both Microcells™ are
mounted with the lead wires on the “down” end.
DISTRIBUTION OF MICROCELL™ SETS
The distribution of Microcell™ sets on beams is
dependent on vessel support configuration. Figure
4-2 shows the distribution of sets for eight support
configurations, varying from independent vessels
to multiple vessels with common columns and
beams. Note in all cases with common beams
between multiple vessels, the common beams are
not instrumented with Microcells™.
