Section IV: Wiring
a) Siren Connections
The type of speaker harness you receive depends on the number of speaker cells present.
For systems consisting of 1 to 5 speaker cells, a 5-pair harness cable is provided. This cable
has 5 BLACK wires numbered 1 to 5 and 5 RED wires numbered 1 to 5. For systems with 6
to 10 speaker cells, a 10-pair harness cable is used. This wires in this cable are designated as
follows:
10 BLACK wires numbered 1 to 10
10 RED wires numbered 1 to 10
In systems with unused wires, dress the unused wires so they are out of the way. Do not cut
these wires, as they can be used to replace damaged wires in the future.
NOTE:
The following procedure provides the information necessary for successfully
connecting the siren harness wires to their designated amplifiers. Depending
upon the distance between the siren base and the electronic cabinet, there will
be varying lengths of wire remaining in the cabinet. It is the installers
responsibility to properly trim and dress these wires in a fashion that not only
leaves the wires organized, but also includes a service loop of suitable length.
1.
Locate the siren wiring harness where it enters the electronic cabinet.
2.
Locate the BLACK and RED wires marked 1 on their insulation. These wires are
designated for connection to siren amplifier 1.
3.
Route these wires through the cabinet's wire loom and connect to Amp 1 (see "Fig.
13: Siren Amplifier Connections" on page 27).
4.
Repeat steps 2 and 3, substituting the appropriate number for all remaining
amplifiers.
5.
When all amplifiers have been wired, install loom cover.
Authors Note: Prior to this writing, systems with 6 to 9 speaker cells received a 9-pair harness
cable, with Red and Black wires numbered 1 to 9. Systems with 10 speaker cells received two, 5-
pair cables. One cable used Red and Black wires numbered 1 to 5, while the remaining cable used
Red and Black wires numbered 1A to 5A (to be used for amplifiers 6 thru 10).
