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.

System Operating Instructions ——————————————

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 must read the following operating instructions concerning system equipment and the terms used in conjunction with the equipment.

NC150N, NC200N Master Stations

Refer to Figure 1 for locations, names, and functions of controls and indicators.

Answer Normal Calls:

Normal calls are indicated by simultaneous operation of the following signals:

• Steady illumination of the associated station selector lamp which is marked to indicate call origin.

• Steady illumination of call lamp.

• Slowly pulsing audible tone. The audible call signal may be canceled for normal calls by pressing the TONE OFF button. The button will then illuminate to indicate the tone is silenced. Pressing the TONE OFF button when illuminated resets the call tone.

To establish conversation with the calling station, press the associated station selector button. The remote station’s RESET lamp will illuminate. To speak to the caller, press the TALK button while speaking and release to listen.

When the conversation is complete, press the associated station selector button to release the station. The remote station’ s RESET indicator will turn of f. Normal calls placed from an IR155B Station must be canceled at the point of origin.

Answer Normal Calls Using Optional TA150N or TA200N Handset:

To establish conversation with the calling station, press the associated station selector button. The remote station’s RESET lamp will illuminate. To speak to the caller, lift the handset from the cradle and begin normal two-way conversation. When the conversation is complete, press the associated station selector button to release the station. The remote station’s RESET lamp will turn off. Replace the handset in the cradle. Normal calls placed from an IR155B Station must be canceled at the point of origin.

Answer Emergency Calls:

All emergency calls take precedence over any normal call signal. Emergency calls must be answered in person and can only be canceled from point of origin. Emergency calls are indicated by simultaneous operation of the following signals:

• Rapid flashing of the associated station selector lamp, which is marked to indicate call origin.

• Rapid flashing of call lamp.

• Rapidly pulsing audible tone.

Answer Code Calls:

All code calls take precedence over any normal or emergency call signal. Code calls must be answered in person and can only be canceled from point of origin. Code calls are indicated by simultaneous operation of the following signals:

• Very rapid flashing of the associated station selector lamp (twice the rate of emergency call), which is marked to indicate call origin.

• Very rapid flashing of call lamp (twice the rate of emergency call).

• Very rapidly pulsing audible tone (twice the rate of emergency call).
