System Operating Principle
Each system uses a series of bus conductors to carry the operating and signaling voltage
to the various units. In addition, each station capable of calling the master station has
individual conductors between it and the master to give the station its own identity.
When a call button is depressed, switching circuits operate to light various call lights and
to energize system call tone. All calls must be reset at the point of origin.

1/3-second intervals. A normal call is indicated by a steady lamp and an intermittent
tone at approximately 8-second intervals.
The Tek-CARE®NC110 Nurse Call System includes three basic units, each essential for
operation. These will be discussed individually and are as follows:
• Power & Control Unit
• Master Station
• Call Stations
The use of these basic units, in conjunction with wiring, housings and auxiliary equipment,
make up a complete system.
PK152, PK151A Power & Control Units
The power & control unit utilizes a transformer which steps down the 120 VAC input to

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.
PK800A Secondary Power Supply
The secondary power supply accepts a 24 VAC input from the SS100 transformer. It

Effective 7/2017, the PK800A has been discontinued. It is documented in this manual
for reference purposes only.
NC110N Master Stations
The Master Station includes:
• Buzzer for audible signals.
• Annunciator lamps for call indication.
• Additional operating controls, including tone off and tone test switches and
additional emergency and normal call indicators.
