Wiring
The 3920 siren provides six 1/4" Quickslide connections on the printed circuit board for power, control and
speaker connections. Each printed circuit board connection is clearly marked for easy identification. Wiring
connections are shown in Figure 2.
Provide a "service loop" of six to eight inches of each wire coming to the siren to allow easy removal and
access to the siren.
