Installation
Mount the
Elemec3
System Controller in the 19-inch rack using the supplied hardware.
The following is a discussion of the types of
Elemec3
systems that can be configured. Refer to your
system manual for complete information.
Single System
In a
single
type system, the
Elemec3
System Controller is typically installed in the top position of a
standard EIA 19-inch
Elemec3
system equipment rack. It requires 1U (1.75 inches) of height.
Duplicate System
In a “
duplicated
” or redundant system, two
Elemec3
System Controllers, designated as A and B, are
located in system racks at different location. In this type of system there are two sets of amplifiers (also
designated as A and B) with the two speaker loops run in different routes. If one
Elemec3
System
Controller should fail, there would be a 50% loss of audible coverage.
Hot Standby (N+1) System
In a different type of redundant system, referred to as a
Hot Standby (N+1)
, two Controllers, designated
as A and B, are located in the same cabinet and control a single set of amplifiers. The advantage to this
type of system is that there is no loss of coverage if one
Elemec3
System Controller should fail.
