Administrative Station Wiring
Administrative stations are wired to the control center through a junction box as shown in Figure 17. The administrative
station is equipped with a PRS40C power supply which must be plugged into a 120V, 60Hz wall outlet
.
CA21B Call-In/Privacy Switch Wiring
When a station includes the CA21B, the white wire from the CA21B must be connected to the center tap of the
station speaker transformer. The center tap of the transformer depends upon the power tap chosen for the speaker.
To determine the appropriate center tap, determine the power tap of the station speaker and use Figure 18 to deter-
mine the color of the wire that is the center tap of the transformer. Connect the white wire of the CA21B to the center
tap. Note the 4-watt power tap does not have a center tap; the privacy feature cannot be used in this case.
