OBSERVE PROPER POLARITY when
making these connections. The striped
wire is common and goes to position 2.
The solid colored wire is signal high
and goes to position 1. Each speaker
connection is color coded. Refer to the
table below for wiring and position.
The bottom module in the speaker
array is an inactive module. This
means there are no drivers contained
in the module. The next module up is
called module number one. The next
one above module one is called
module number two etc. These are
referred to as active modules. Each
active module contains four (4) drivers
(2 pairs).
Each pair is connected in parallel. The
drivers contained in module number
one are labeled A 1 and 2 (wired in
parallel) and B 1 and 2 (wired in
parallel). A, C, E, G, I, and K drivers
are in line with the conduit fitting at
the base of the siren. Module number
2 contains drivers C and D etc. Refer
to figure 3-3 for driver orientation and
wire location for active module one
only.
Each speaker array is supplied
with a 50 foot cable. The number of
conductors and colors vary from
module to module. Model MOD4016
and MOD6024 contain junction boxes
in series with the 50 foot cable to allow
connection to the speaker array. Refer
to list below for number of wires per
module and how many wires are used.
MOD1004 - 8 wires only 4
are used.
