annunciator lamps on that panel should be illuminated. (See System Maintenance
Instructions for proper procedures and precautions in replacing defective lamps.)
Improper Operation:
• If the NC110N Master Station fails to operate as described, contact qualified service
personnel.TherearenouserreplaceablepartsontheNC110NMasterStationotherthan
the station selector lamps and lenses.
• Ifamalfunctionoccursduringacallandcausesalackofindicationofcalloriginonthe
master station, first determine the origin of the call by observing which corridor light
andcorridor zone lightis illuminated, then inform qualified service personnel.
NC110A Master Stations
Refer to Figure 2 for locations, names, and functions of controls and indicators. Operation
of the NC110A is similar to that of the NC110N, except that there is no selector lamp test

desired level is reached. The level is indicated by three lighted LEDs above the volume
button. Use the tone test button to test volume when adjusting the volume.
Selector point labeling:
A slot is provided at the top of each column of selector points for inserting a paper strip
(TekTone®part numberLB516).Applyroom-identifying labelsbetweenthe dashedlines so
that each label lines up with the intended selector point on the NC110A membrane switch.

a slowly pulsing audible tone. Push the TONE OFF switch down to silence the audible tone
signal. Push the TONE OFF switch up to turn the audible tone signal on.
ImproperOperation: Ifthe call station does not operate as described, contactqualified service
personnel. There are no user serviceable parts on the LI150N and LI150B Duty Stations.
LI381 Corridor Lights
Emergency Calls: Emergency calls are indicated by rapid flashing of the corridor light that
is associated with the calling station.
Normal Calls: Normal calls are indicated by steady illumination of the corridor light that is
associated with the calling station.
Lamp Replacement: See System Maintenance Instructions for proper procedures and pre-
cautions in replacing defective lamps.
Improper Operation: If corridor light does not operate as described, contact qualified ser-
vice personnel. There are no user serviceable parts on the LI381 Corridor Lights other
than lamps.

light(s) associated with the zone or area from which an emergency call has been placed.
Normal Calls: Normal calls are indicated by steady illumination of the white corridor zone
light(s) associated with the zone or area from which a normal call has been placed.
ConcurrentEmergency andNormalCalls:Ifan emergency and normal callare placed inthe
same zone at the same time, the red light(s) connected to the emergency station from
which a call was placed will flash rapidly, while the white light(s) associated with the
normalcall will maintain a steadyillumination.

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.
Emergency calls are signaled by a different flashing rate at the master station.An emergency
call is indicated by an intermittent tone and flashing lights at approximately 1/3-second
intervals.Anormalcall isindicated by a steady lampand anintermittent toneat approximately
8-second intervals.
The Tek-CARE®NC110N Nurse Call System includes three basic units, each essential for
operation. These will be discussed individually and are as follows:
• Power&ControlUnit
• Master Station
• CallStations
The use of these basic units, in conjunction with wiring, housings and auxiliary equipment,
make up a complete system.
PK151A, PK152 Power & Control Units
The power & control unit utilizes a transformer which steps down the 120 VAC input to 24
VAC, 30VA,which is then rectified, filtered and regulatedto provide a stable 24VDC for the
rest of the system.
Control circuits are provided to detect the presence of normal or emergency calls and to
providesteady or intermittent voltages tooperate externaldevices 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
Thesecondary power supply accepts a 24VAC input fromthe SS100 transformer. It rectifies,
filters and regulates a +24 VDC output, which is provided on the two terminals labeled “24
VDC.”A+5 VDC output is also available, but is not used in this application.
NC110N Master Stations
The Master Station includes:
• Buzzerforaudiblesignals.
• Annunciator lamps for call indication.
• Additionaloperatingcontrols,includingtoneoffandtonetestswitchesandadditional
emergencyand normal callindicators.
