CTPhone 1900 System Hardware & Software Installation
Base Station Input Power
The base station may receive input (line) power from the CTPhone Con-
troller or from an optional local power supply. Using a power supply
increases the distance base stations may be located from the CTPhone
Controller.
CTP Systems provides an optional universal 115/230 V, 50/60 Hz power
supply with barrel jack connection to the base station [P/N PSY30102, also
requires a power cord (P/N CBL30001)]. The specifications for the con-
nection are shown in Figure 3-6.
Figure 3-6. Base Station Local Power Supply Specifications
5 On wall-mounted the base stations only, rotate antennas par-
allel to the body of the base station. (Antennas on ceiling-
mounted base stations should remain rotated perpendicular
to the base station.)
6 Connect the transmit cable (pair 21 or 25) to the base sta-
tion’s receive jack (see Figure 3-5).
7 Connect the receive cable (pair 20 or 24) to the base sta-
tion’s transmit jack (see Figure 3-5).
