Description

Tektone PK152 (PK152) Power and Control Unit for NC110, NC150, NC200 Systems.

The power & control unit utilizes a transformer which steps down the 120 VAC input to

24 VAC, 30 VA, which is then rectified, filtered and regulated to provide a stable 24 VDC

for the rest of the system.

Control circuits are provided to detect the presence of normal or emergency calls and

to provide steady or intermittent voltages to operate external devices with indications

as follows:

Normal calls are indicated by a positive voltage applied to Terminal R by the calling

remote station. Emergency calls are indicated by a positive voltage applied to terminal

Q by the calling remote station.
