d. Run wires from power source, through conduit to the SelecTone unit. Wire size depends
upon the operating current and the distance from the power source. Install 1/2-inch

E. Electrical Connections.
1. Single Unit Installations.
Connect one of the SelecTone power leads through an on-off switch, or other switching
device, to one side of the power line. The on-off switch must be capable of carrying the
current drawn by the SelecTone. Connect the remaining SelecTone power lead to the other
side of the power line. When the SelecTone is operated from a DC source, be sure to
observe polarity. When operated from an AC source, connect the black power lead to the
phase side of the line and the white lead to the common side of the line. Install the tone
module in P2 (see figure 2). After installation, check to ensure that the unit is operating
properly.
2. Multiple Unit System Installations.
Connect the SelecTone power leads to the power source. When operated from an AC
source, connect the black SelecTone power lead to the phase side of the power source and
the white or red lead to the common side.
Install a Connector card in P2 as shown in figure 3 or 4. Connect the leads on the Connector
card to the signal leads from the SelecTone Command. Refer to the applicable Selectone
Command instruction manual for further instructions. For the 300CK, refer to Federal Signal
Part No. K2561044 (Model 300VSC-1 SelecTone Command) or Federal Signal Part No.
K2561090 (Model 300SCW-1 SelecTone Command). For the 300CKS, refer to Federal Signal
Part No. K255A204 (Model 300SSC Supervised SelecTone Command). For the AM25CK and
AM70CK, refer to the instructions packed with each unit. After installation, check to ensure
that the unit is operating properly.
F. Speaker Positioning.
The SelecTone is constructed to allow adjustment of the speaker to almost any horizontal
position. This repositioning of the speaker is accomplished by rotating the speaker. When
repositioning the speaker, never rotate the speaker more than 180° or the speaker wires may be
damaged. To reposition the speaker, loosen the collar nut that secures the speaker and rotate
the speaker to the desired position. Tighten the collar nut.
