Tek-CARE® NC150 and NC200 series Intercom Nurse Call Systems are designed for nursing
home or individual hospital ward use. The T ek-CARE® NC150 and NC200 systems provide
selective two-way audio and visual communication from master station to staff and patient
stations, as well as emergency signaling and call indication from remote locations.
Emergency calls are indicated by a rapid pulsing of all audible and visual signals associated
with the calling station. Emergency calls take precedence over normal calls and can only
be canceled at the point of origin.

A Word about ESD (Electrostatic Discharge)————————
What Is It? Static electricity is a result of triboelectric charging of two dissimilar
nonconductive materials that are rubbed together, such as rubbing your feet on a carpet on
a cold winter day or in a dry climate. The resulting charge is detected when you reach out
to touch a doorknob or some other metallic object. The resulting discharge may only be
startling or, in severe cases, it may even be painful. The actual electrical char ge is dependant
on the materials being rubbed together, humidity, the rate of separation, and other factors.
What Can It Do? While this effect may be disturbing to humans, the effect on electronic
equipment is often more serious, ranging from operational disruption to actual component
damage. These effects result from the high voltages that may be developed. The simple act
of walking across a carpet may develop as much as 30,000 volts, and changing a bed sheet
may create a charge of 100,000 volts or more. Such voltages readily cause arcing (the
spark that can be observed when you grab a doorknob after walking across a carpet, etc.).
The arcing is evidence of the discharge path. Due to the high voltage involved, the discharge
current can jump to any nearby metallic or non-metallic object. If the discharge is to or
through an electronic device, such as the nurse call system, the operation of the device may
be affected. If the discharge current passes through internal components, these components
may be damaged or their operation degraded.
What Can We Do About It? The manufacturer of the nurse call equipment has already
taken steps to protect the equipment from electrostatic discharge (ESD) effects. However,
since the cause is not in the equipment, but in the environment, further measures are
required of the installer and the user to achieve complete protection.
What The Installer Can Do: In humid climates or in places where the relative humidity is
kept at 65% or greater, there will likely be few problems with ESD. Where problems may
occur the following measures can be taken.
•Ground all exposed metal surfaces. Grounding should be to a #16 gauge or larger
conductor.
•Install nurse call system wiring in metal conduit. This conduit may be used to ground
panels.
•Use shielded cable for nurse call system station-to-station wiring. The use of open
conductors invites inductive coupling of discharge currents, which can cause the
same problems as direct discharge currents.
•Ground your body before handling system components. This can be done by using a
wrist strap, or simply by contacting a grounded metal surface. Use caution to avoid
hazardous voltages while grounded.
What The User Can Do: The most common generation of ESD in hospitals is due to
changing linen on hospital beds while the patient call cord or pillow speaker is still connected
to the nurse call system. The following precautions will help.
Remove the call cord or pillow speaker from the bed before changing the linen. It will be
necessary for the nursing staff to discharge themselves by contacting a grounded metal
object before placing the call cord or pillow speaker back on the bed; otherwise a spark will
jump to the nurse call equipment, causing the very damage they are trying to avoid. To
avoid a shock while discharging static electricity on the body, hold a metal object, such as
a key, and use that object to contact the grounded surface.
This information is provided to make you aware of ESD problems so that precautions may
be taken to avoid damage and disruption of system operation.
This section provides complete operating instructions for all Tek-CARE® functions, as
well as reference drawings for use in locating and describing all controls. System operators
