1.0 SYSTEM INTRODUCTION

The NC205 Nurse Call System is a supervised, microcontroller based system that provides a complete range of two-way audio and visual signaling for staff-to-patient and staff-tostaff communications.

The NC205 Nurse Call System is complemented by a wide range of bedside stations and peripherals:

• duty and staff stations

• single and dual patient stations

• dome and zone corridor lights

The NC250/NC230 Master Stations and NC255 Master Expander make up the control console where patient calls are registered and displayed. The control consoles provide facilities for:

• locating and dispatching staff personnel

• code, emergency, bath, and

staff presence peripherals The features of the master stations, bedside stations, and peripherals are discussed in greater detail in Section 3.0System Equipment Description.

• managing patient priority and privacy

• monitoring all emergency situations

• performing system configurations

• monitoring code, communication, station,

and central equipment faults.

Simplified wiring and plug-in design provide ease of installation in new and/or existing facilities. Modular circuitry and interchangeable room stations permit the system to be easily upgraded and expanded at anytime.

A WORD ABOUT ELECTROSTATIC DISCHARGE

What Is It? Static electricity is a result of triboelectric charging of two dissimilar nonconductive materials rubbed together, like 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 be only startling, or in severe cases it may even be painful. The actual electrical charge is dependent on the materials rubbed together, humidity, 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 disrupting the operation to actual damage of the components. 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; changing a bed sheet may create a charge of 100,000 volts or more. Such voltages readily cause arcing (the spark you see in the dark when you grab the doorknob, after walking across the carpet, etc.). The arcing is evidence of a discharge path. Due to the high voltage involved, the discharge current can jump to any nearby 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 of the problem 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.

1. Ground all exposed metal surfaces, such as patient station panels, etc. Grounding should be to a #14 or larger conductor.

2. Install nurse call system wiring in metal conduit. This conduit may also be used to ground panels. The conduit must be electrically continuous and be grounded.

3. Use shielded wire in 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.

4. Ground your body before handling system components. This can be done using a wrist strap, or simply by contacting a grounded 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.

1. Remove the call cord or pillow speaker from the bed before changing. 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.)

2. Ground the bed and use antistatic mattress covers in contact with the bed frame. For safety, it may be desirable to make the ground connection through a 1 megohm resistor. Nursing staff must be trained to disconnect and reconnect the ground whenever beds have to be moved.

3. Use grounded appliances and equipment near nurse call systems. The use of approved electrical equipment will usually take care of this.

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.

2.1 EQUIPMENT SUMMARIES

NC260B Central Equipment

The NC260B provides microcontroller, signaling, and power circuitry (except in applications requiring the PK261A) to operate the NC205 Nurse Call System. The central equipment may interface with up to four NC250/NC230 Master Stations and their NC255 Master Expanders, and one NC262A Central Equipment Expander. The central equipment consists of microcontroller, memory, interface, and power supply circuits. All outputs are protected by self-resetting current limiting circuitry. All equipment is completely contained in a hinged surface mount cabinet. A recommended backup battery kit is available.

NC262A Central Equipment Expander

The NC262A provides the additional circuitry necessary to interface with the NC260B Central Equipment and two additional PM261A Selector Cards. It also includes an additional power supply. This enables the system to be expanded to 128 remote stations.

NOTE: A 128 remote station (maximum) system would

require:

1 - NC260B with 2 - PM261A’s 1 - NC262A with 2 - PM261A’s

PK261A Dome Light Power Supply

The PK261A Dome Light Power Supply provides power for dome lights connected to enhanced patients stations (IR254-

259). Connections to dome light field wiring are provided via

a plug-on connector.

NC250 Master Station

The NC250 utilizes digital technology to provide communications, fault monitoring, and programming for the NC205 Nurse Call System. The master station consists of a handset, volume control, speaker, microphone, 8 color-coded function buttons, 50 individual room selector buttons, and LED’s for call priority, power, and fault. All LED’s and buttons are on a spill-proof membrane switch assembly.

NC230 Master Station

The NC230 has the same functionality as the NC250 but provides 30 individual room selector buttons with LED’s.

NC255 - 50 Station Master Expander

The NC255 provides the additional circuitry and buttons to expand the capacity of a master station by 50 rooms. Call LED’s and selector buttons are on a spill-proof membrane switch assembly.

PM261A Selector Card

The PM261A provides connection points for up to 32 stations. Integrated digital and analog technology provide for reliable communications between system components. Each NC260B/ NC262A is capable of supporting two PM261A Selector Cards to provide access for up to 64 IR Series Remote Stations.

IR250 Standard Staff Station

The IR250 provides reliable two-way, hands-free communication between the nurse master station and any location where staff members may need to originate calls or where cord sets are not required. It may also function as a push button patient station. The station contains a combination yellow “CALL-PLACED” indicator and “CALL” button, a combination red “IN-USE” indicator and “RESET” button, and a speaker/microphone. The IR250 is mounted on an attractive flame retardant type ABS plastic faceplate. The IR250 operates with single and dual lamp dome lights (LI381/ LI382), and has inputs for “BATH/EMERGENCY” and “FIRE.”

IR251 Single/IR252 Dual Standard Patient Stations

The IR251/IR252 stations include yellow “CALL-PLACED” indicator(s), patient call cord receptacle(s), a combination red “IN-USE” indicator and “RESET” button, and a speaker/ microphone. The stations use 1/4" phone jack(s) and are mounted on attractive flame retardant type ABS plastic faceplates. Both provide outputs for single/dual light dome lights (LI381/LI382) and two peripheral devices (“EMERGENCY” and “FIRE”).

IR253 Standard Pull Cord Patient Station

The IR253 has all the same functions as the IR251/IR252 Stations, but provides a patient pull cord instead of call cord jack. The IR253 consists of a yellow “CALL-PLACED” indicator, a combination red “IN-USE” indicator and “RESET” button, and a speaker/microphone. The IR253 is mounted on an attractive flame retardant type ABS plastic faceplate, and provides outputs for single and dual lamp dome lights (LI381/ LI382) and two peripheral devices (“EMERGENCY” and “FIRE”).

When your equipment is received:

The ground clip of a ground strap should be connected to the chassis ground lug in NC260B unit prior to working with NC205 equipment.

Step 1:

Locate the following devices:

• Master station(s) (NC230 or NC250) and associated CA037/7

• Master station wall plate(s) (PL467) and connector harness(es) (CT308/24)

• Master station expander(s) (if used) (NC255) and associated CA037

• Central equipment (NC260B) and associated ground interconnect cable

• Central equipment expander (if used) NC262A, associated CT261, and associated ground interconnect cable

• Selector card(s) (PM261A)

• Common wire harness and selective wire harness

from PM261A selector card (CT306/24 and CT308/

24)

• Remote (patient, staff, or duty) station (IR250 - IR258 or IR260A)

• AC power cords (CA038), one for NC260B and (if used) one for NC262A

• Remote stations common wire harness and (CT307)

Step 2:

If selector cards are already installed, skip to step 3. It is important that selector card #1 be installed before power is supplied to the system. Install the selector cards onto 15 pin connectors near the top edge of PM260B Motherboard in the NC260B Central Equipment as indicated in NL205-E. It is very important to ensure that all pins are inserted properly. Improper pin insertion or pins not inserted will cause damage to PM260B or PM261A modules. If an NC262A Central Equipment Expander is used, insert associated PM261A modules also, referencing NL205-F.

NOTE: The NC260B Central Equipment includes a removable “sled” that allows for the removal of the PM260B Motherboard and associated PM261A selector cards (reference label inside of NC260B for removal instructions). The sled should be removed during IH260 housing installation process to prevent damage to electrical equipment or PM261A selector card replacement for ease of card installation.

Step 4:

Plug the 8 pin connector of a master wiring harness to master connector number 1 as indicated in NL205-E and NL205-G.

Step 5:

Insert one end of CA037/7 cable (included with master station ) into the PL467 plate of the master wiring harness.

Step 6:

Select a master station and insert the other end of CA037/7 cable into the master station receptacle referred to as “Master IN” in NL205-G .

Step 7:

The master station used should be set to address number 1. This is accomplished by setting all four dipswitches (accessible via an opening in back of master cabinet) to the “OFF” or “UP” position as indicated in figure 9.

Step 8:

Locate the CT306/24, CT308/24, and CT307 connectors. Connect them together as shown in NL205-E, NL205-I, NL205-J, NL205-K, NL205-L, NL205-M, NL205-N depending on the type of station used for test. This station connector harness will serve to connect the remote station to the NC260B for this procedure.

Step 9:

Plug the 6 pin connector of station connector harness on to either 6 pin common connector of the PM261A Selector Card, within NC260B, as referenced in NL205-E.

Step 10:

Plug 8 pin connector of station connector harness on to bottom most 8 pin selector connector of the PM261A Selector Card as referenced in NL205-E.

Step 11:

Plug 7 pin connector of station connector harness on to the 7 pin connector of test remote station. Reference NL205-I, NL205-K, NL205-L, NL205-M, or NL205-N depending on the type of station used for test.

Step 12:

Set dipswitch number 1 on the PM260B Motherboard to the “ON” position as referenced in section 5.4-1, Central Equipment Reset Procedure. This dipswitch setting will cause the “flash-ram” in the NC260B to be cleared on power up.

Step 3:

Locate the associated PL467 and CT308/24 for each master station. The CT308/24 should be connected to the PL467 as shown in NL205-G of the IL600 manual, creating a master wiring harness. A harness should be made for each master station.

Insert other end of CA038 cable into 110VAC outlet.

“ON” or “UP” position, leaving switches 2 and 3 in the “OFF” or “DOWN” position. Switch 4 will be factory set as per

Figure 10. Wait until the LEDs on the PM261A Selector Cards begin to flash. NOTE: Flashing pattern is irregular and is not an indication of a FAULT condition. Return dipswitch number 1 on the PM260B Motherboard to its original “OFF” position. If PM261A LED(s) do not flash, re-check master station wiring.

Step 18:

Insert one end of the master expander’s CA037 interconnect

cable into the master station receptacle referred to as “Ex-

pander OUT” in NL205-G.

At this time the NC205 set up should be operating properly with no “FAULT” LEDs lit on the bottom edge of the PM260B Motherboard.

Step 15:

The master station’s “flash-ram” must now be cleared. To accomplish this, set dipswitch number 4 to the “ON” or “DOWN” position. Now set dipswitch number 1 to the “ON” or “DOWN” position and then return it to the “OFF” or “UP” position. Wait, before proceeding, to verify that the master stations’s “TALK” LED illuminates for a brief period of time (NOTE: This should occur within 10 to 15 seconds.) If this does not occur, perform step 15 again. Return dipswitch 4 to the “OFF” or “UP” position.

At this time, no “FAULT” conditions should be annunciat- ing from the master or central equipment. If any “FAULT” LEDs are lit, note the “FAULT” as shown in section 5.6-2, Faults (for central equipment) or in section 3.3, Master Station and Expander Displays (for master station). Once the “FAULT” condition has been noted, remove power from the system.

If no “FAULTS” have occurred, place a call from the remote station by depressing the call button on the station or associated call cord. This call should be annunciated at the master station by a beeping tone and a flashing yellow LED. Press the selector button associated with the LED and the master station will open an audio path to the station. This will be indicated by the red “IN-USE” LED lighting on the remote station. There will be some acoustic feedback due to the close proximity of the master and station.

As the procedure is followed, the operation of the system should be observed for the introduction of functional problems and audio noise each time equipment is added. If a problem becomes apparent, the last system addition should be suspect.

Step 19:

Insert the other end of the CA037 interconnect cable into the

master expander receptacle referred to as “Expander IN” in

NL205-G.

Step 20:

Repeat steps 12 - 15 to power up system.

Step 21:

Repeat steps 16 - 20 until all master expanders for the master

station are connected. NOTE: Each master station expander

must have a unique address as per figure 10. Connection of

incorrectly addressed master expanders will result in dam-

aged equipment. Additional expanders will connect to the

“Expander OUT” receptacle of the previous master expander.

Reference NL205-G.

Step 22:

Repeat steps 4 - 21 until all master stations and master ex-

panders are connected. NOTE: Each master station should

have a unique address indicated by figure 9. Each master

station’s address should correspond to the connector it is

plugged into on the PM260B motherboard as indicated by

NL205-E and NL205-G. (I.e., master number 2 should be

plugged onto master connector number 2 and so on, respec-

tively.)

Step 23:

If a central equipment expander is used, locate and address

all three sets of dipswitches within the NC262A Central Equip-

ment Expander to number 1 by sliding dipswitch 1 to the

“ON” or “UP” position. Dipswitches 2, 3, and 4, should be

set to the “OFF” or “DOWN” position.

Step 24:

Connect the NC262A to the NC260B unit by inserting the

male end of the CT261 into the female DB25 receptacle within

the NC260B chassis. Reference NL205-E and NL205-F.

Step 16:

Power down system by removing the CA038 from the 110 VAC outlet.

Step 17:

If master station expanders are used on the system, select one unit and set its address to be master expander number 1

Step 25:

Take the ground interconnect cable from the NC260B Central

Equipment and connect to the NC260B chassis ground lug.

Take the ground interconnect cable from the NC262A and

connect to the NC262A chassis ground lug. Connect the

NC262A chassis ground lug to the NC260B chassis ground

lug (wire nuts or electrical tape is suggested for insulation of

IL600 NC205 Tek-DIGICARE® Manual • 13

Page 24

connections). Reference NL205-E and NL205-F for locations to insert ground interconnect cables within the NC260B and NC262A chassis. NOTE: The NC262A unit requires a 110 VAC connection source for power (reference step 13 for connection). NOTE: Only qualified technical personnel should

make 110 VAC connections! Do not connect CA038 to 110 VAC outlet until 110 VAC terminal block connections are made and the safety cover is reinstalled on to the terminal block.

The audio quality should be observed and if noise is present the shields for the master cable wiring (which should be connected to the NC260B chassis ground lug as indicated by NL205-E) should be checked for proper connection and undesired grounds. The earth ground connection to the NC260B chassis should also be checked.

Once the master station and master station expanders are operating properly, proceed to step 3.

Step 26:

Follow steps 12 - 15 to power up system and test the NC262A unit.

Personnel planning to install this equipment should take this opportunity to familiarize themselves with basic system operations. See section 4.0, Operational Procedures, for operational instructions of the NC205 system.

When your equipment is installed:

The above listed procedure should be followed at the jobsite and operation of the NC205 equipment should not change. Usually, this setup will be performed in an electrical or other dedicated room once the NC260B and NC262A housings have been mounted.

NOTE: The CA038 is not intended for field installation and should be removed prior to site installation!

Once the installation personnel have achieved the operational state described in the above steps 1- 30, connection of field devices may commence, following the procedure listed below.

Step 1:

Ensure that NC205 system is powered down and that dipswitch number 1 on the PM260B motherboard is in the “ON” position to allow new equipment to be recognized. After each power up the installation personnel should wait for the PM261A Selector Card(s) LED(s) to begin flashing and then dipswitch number 1 should be returned to the “OFF” position. Observe the PM260B Motherboard for “FAULT” indi- cations.

Step 3:

Repeat steps 1 and 2 for each master station, until all masters and master station expanders are operational. The operation of the system should be observed each time for the introduction of functional problems and audio noise. If a problem becomes apparent, the last system addition should be suspect.

Step 4:

Ensure that the NC205 system is powered down and that dipswitch number 1 on the PM260B Motherboard is in the “ON”position.

Step 5:

The wiring to the first remote station common wire cable run should be verified and checked for shorts and grounds. Reference NL205-I, NL205-J, NL205-K, NL205-L, NL205-M, NL205-N, NL205-O and NL205-P. Connect the common wires of the first station run to the PM261A Selector Card common connector as indicated by NL205-E.

Step 6:

The wiring to the first remote station selective wire cable run should be verified, checked for shorts and grounds. Connect the selective wires of the first station run to the PM261A Selector Card selective connector(s) as indicated by NL205E.

Step 7:

The local peripheral wiring for each remote station connected to the first cable run should be verified and checked for shorts and grounds. Reference NL205-I, NL205-J, NL205-L, NL205M, NL205-N, NL205-O and NL205-P.

Step 2:

The wiring to the first master station should be verified and checked for shorts and grounds from the central equipment location to first master station location. Once done, the first master station, and associated master station expanders, may be connected at its field location. The system should be powered up and checked for fault conditions. If fault conditions occur, they should be noted and then the system should be powered down. The wiring should be re-checked for problems. If problems are located, correct and proceed with step 2 again.

14 • IL600 NC205 Tek-DIGICARE® Manual

Step 8:

Power up the NC205 system and wait for the LED(s) on the PM261A Selector Card(s) to begin flashing. Return dipswitch 1 on the PM260B Motherboard to the “OFF” position. Observe the PM260B Motherboard for “FAULT” indications.

Step 9:

A call should be placed and answered by a master station from each remote station connected to the first run. The system should be observed so that operational anomalies may be identified. During observation, each peripheral device connected to the remote station(s) should be activated.

Page 25

Step 10:

Repeat steps 4 - 9 for each remote station cable run, until all remote stations are operational. The operation of the system should be observed each time for the introduction of functional problems and audio noise. If a problem becomes apparent, the last system addition should be suspect.

4.0 OPERATIONAL PROCEDURES

4.1 MASTER STATION & EXPANDERS

4.1-1 Calling

NOTE: All follower functions must be reset before calling functions can be engaged.

A. To answer a call, press the illuminated station selector

button and wait for “TALK” LED to light; then press the “TALK” button while speaking and release to listen, or pick up the handset (if the handset is being used, it is not necessary to press the “TALK” button ). The call tone will be silenced and communications will be established to the selected room. If pre-announce call tones are “ON”, a one second tone will be heard at the master and room station when the station selector button is first pressed.

When answering multiple calls, the call in progress must be reset before attempting to selectively answer a subsequent call. To reset the current call, the “RESET” button may be pressed, or the handset must be placed in its cradle–the user must wait for the new call to be registered before attempting to establish communications (do not attempt to use the hook switch to reset the call).

Calls can also be answered by pressing the “TALK” button without first selecting a station. When used in this manner, the higher priority calls are answered first. Once these calls have been cleared, then the lower priority calls are answered next.

NOTE: If a high or medium priority call is placed while a master station is in communication with another station, the “TALK” function with the current low priority call will only be active for 8-10 seconds; then the current call will be placed on hold, and the higher priority call will automatically reactivate the call tones at the appropriate rate. “TALK” must be pressed to connect audio; once the higher priority call is reset, the lower priority call can be answered again.

B. To place a call, press the desired station selector

button; then press the “TALK” button or pick up the handset. If pre-announce call tones are “ON”, a one second tone will be heard at the master and room station when the station selector button is first pressed. Calls may be placed to patient, staff, or duty stations in the same manner. Calls placed from master stations must be reset at the master.

“CALL” must have its own selector pushed before communication path will open. (All master to master communications are push to “TALK” only.)

NOTE: If a patient station is in privacy mode, no audio can be heard at the calling master from that station. Privacy does not affect calls initiated from the patient station.

C. To cancel a call, press the “RESET” button or hang

up the handset. Medium, high priority, and personal attention calls must be reset at the point of origin.

D. To upgrade calls in progress, press the “PRIORITY”

button while the master is in communication with the station (see Section 4.1-5C).

If master stations are in communication, each can discontinue communications in order to respond to another station by pressing the “RESET” button. Incoming high or medium priority calls automatically cancel master-to-master communications after eight seconds.

4.1-2 Staff Service

Staff service functions are not available on IR250-IR253 and IR260A Standard Patient and Duty Stations.

A. To request staff service, press the station selector

button followed by the “STAFF” button; then press “RESET”.

B. To cancel a staff service request or staff presence,

press the station selector button followed by the “STAFF” button; then press “RESET”, or cancel at patient station by pushing the “RESET” button.

C. To view staff status, press the “STAFF” button.

Stations with staff requests pending will be indicated by the fast flashing of that station’s selector button LED. Stations that have staff presence registered will be displayed with a slow flash rate. This display will clear after eight seconds or when the “RESET” button is pressed (see System Programming Section 5.3-1).

If a called station is in communications, a busy indication will be given by a flashing “TALK” LED. No other visual or audible signals will be generated.

To place a call to another master, press the desired master selector button. The master receiving the

Follower Functions

B. To view and/or change stations in privacy mode,

press the “PRIVACY” button. Stations in privacy mode will display with a flashing LED on their selector button. This display will clear after eight seconds or when the “RESET” button is pressed. To place a station in privacy mode, the station must first be selected and “PRIVACY” pressed followed by “RESET”. This same procedure is used to release a station from the privacy mode.

C. To change the priority status of a station, press the

station’s selector button followed by the “PRIORITY” button; then press “RESET”. This will upgrade the station’s low priority call from a Routine level to Personal Attention which must be reset at the station (Personal Attention not available on IR250-IR253 and IR260A.) Pressing the station’s selector button, “PRIORITY”, and then “RESET” again (immediately following the first upgrade) will upgrade the station’s low priority call from a Personal Attention level to Priority—the call will register at the master as a medium priority call and must be reset at the station. Following the select- “PRIORITY” - “RESET” procedure, once again will revert the station’s status back to a Routine level for low priority calls. For IR250IR253 and IR260A Standard and Duty Stations, follow the same procedure as above. However, these stations only have Routine and Priority levels.

A. To follow a staff member, press the “FOLLOW”

button followed by the “STAFF” button. Call tones will be sent to rooms in the preset zones where staff presence is registered, as well as stations that are marked as staff stations.

B. To follow to a specific room, press the “FOLLOW”

button, then select the room. Call tones will be sent to the selected room only.

C. To discontinue the follower function, press “RESET”.

5.0 SYSTEM CONFIGURATION/PROGRAMMING

The following information should be programmed into the NC205 System by qualified administrative personnel prior to general staff operation. Figure 22 shows the NC250/NC230 Master Station inserts included for system programming. The personnel responsible for programming should see to it that these inserts are not destroyed, distributed, or changed. Information programmed after this time should require few changes. During programming, please ensure that all key strokes are deliberate and that there is a momentary pause between operations.

The numerical selector button LED’s are the first column of LED selector buttons on the NC250/NC230 Master Station. The alpha selector button LED’s are the second column of LED selector buttons. These columns serve dual purposes; the numerical column serves as zone programming switches, the alpha column serves as master and station status programming switches, and both columns serve as normal station selector buttons.

5.1 MASTER STATIONS

Zoning assignments are for use in controlling the patient, staff, and duty stations to which the master station may communicate. They may also be used to control paging, staff follower, and other system functions. Master stations may be assigned to one, all, or any combination of the eight zones supported by the NC205 System. Master stations default to all eight zones.

In multiple master systems only one conversation to one of eight audio paths may occur. The stations are pre-wired to these paths through the default hardware zone number of the PM261A Selector Card to which it is connected (each card represents one audio path/hardware zone).

C. To program master status, press the corresponding

alpha key for:

PRESETS = “A” - “H”

These keys indicate the alpha keys used for preset zones. “A” is the default preset.

BEEP TONE = “I”

When lit, this key indicates that a button pushed on the master keypad will generate a short beep tone. To turn off this feature, press the alpha key so that the LED is off.

PRE-ANNOUNCE TONE = “J”

When lit, this key indicates that a call tone is introduced at both the station and the master when a call is placed. To turn off this feature, press the alpha key so that the LED is off.

D. To view station fault list, press the “ZONE” button

while in the master programming mode. Stations that have reported a fault since the last fault scan will appear with rapidly flashing LED’s. Press the “ZONE” button again to return to the master programming mode (display will clear itself after eight seconds).

Refer to Section 5.3 for additional features such as making a system non-square, adding an expansion keypad, etc. Refer to Section 5.5 for instructions on adding master stations to a system.

5.1-1

Entering the Programming Mode

To configure the master, press the “ZONE” key (system must be on but not being used). A display will appear showing the pre-programmed zones in the numerical key column. The status of the master is displayed in the alpha key column. Once these displays have appeared, the master is in the programming mode.

A. To select zone presets, press the desired alpha key.

The zones assigned to this alpha preset are then displayed in the numerical key column (the master will respond to only these zones). Alpha keys “A” - “H” are used for these zone presets.

B. To program master zones, press zone key 2 more

times, then press the numerical key that corresponds to number of the zone. If the zone is programmed, that number’s LED will light. Pressing the numerical key again will turn off the LED and unprogram that zone. A display of “ZONE # 0” indicates that no zones are programmed (master is off-line). Pressing the “9” key will set all zones “ON”.

5.2 PATIENT STATIONS

Assign station zone assignments following the procedures listed below. The NC205 System should be on but not in use while zone assignments are being entered.

Zoning assignments for each station default to the selector card number they have been connected to (in the NC260B Central Equipment or NC262A Central Equipment Expander). Stations must be assigned to at least one of the eight zones supported by the NC205 System, but may be assigned to additional zones, if desired. Zoning assignments are used to direct station calls to masters that are zoned for those calls.

5.2-1 Entering the Programming Mode

To choose the station to be programmed, press the appropriate station selector button on the NC250/NC230/NC255. The LED associated with that selector button will light as the central equipment establishes communications with the station. Now press the “ZONE” button. The station LED will extinguish and a display showing the zones assigned to the station will appear in the numeric key column; the station’s status will display in the alpha key column.

To recall what station is being programmed, simply push the “ZONE” button again. This will temporarily light the LED of the station originally chosen with a rapid flash. Press the “ZONE” button again to return to programming (display will clear after eight seconds).

A. To assign zones, press the numerical key that

corresponds to the number of the desired zone. If the zone is programmed, that number’s LED will light. Pressing the numerical key again will turn off the LED and unprogram that zone. Pressing the “9” key will toggle the state of all zones.

NOTE: DO NOT assign “ZONE 0” to stations; this will render them off-line. To reactivate a station that has been taken off-line, place a call from that station or reassign it to a zone other than “0”. The central equipment will then validate the station and assign it to all zones.

B. To program station status, press the corresponding

alpha key:

“A” = STATUS

When lit, this key indicates that the station is in a standard mode of operation; no special functions (“B” - “I”) have been assigned. IR254-259 Stations default to the “A” Status. IR250-253 and IR260A Stations default to “F” (Fault Defeat) and

“G” (Fire).

“B”= PRIVACY

When lit, this key indicates that audio communications from the station are inhibited. If a call originates from the station, then normal two-way communications are established. If the call originates from a master, then no audio will be heard from the station at the master, but audio from master will be heard at station.

“C” = PAGE INHIBIT

When lit, this key indicates that paging functions (preset, zone, and all-call paging) are ignored by the station.

“D” = PRIORITY UPGRADE

This key is used to indicate that a station’s

Routine call has been upgraded to the Priority level.(Used for IR250-IR253 and

IR260A only).

“E” = BATH (STAND ALONE)

This key is used to mark devices (Emergency Call Stations, Smoke Detector Contacts, etc.) as stand alone bath/emergency stations. These stations will generate medium priority (EMERGENCY) calls. By default, stand alone stations that are not marked as BATH/STAND ALONE will generate high priority (CODE or FIRE) calls.

“F” = FAULT DEFEAT

This key is used to disable the central equipment’s fault scan for the station. It can be used to temporarily mask a faulty station while repairs are underway. This

key must be set for all IR250/IR251/ IR252/IR253, IR260A and stand alone devices.

“G” = FIRE

When lit, this key indicates that high priority calls from this station are recognized as FIRE calls. (NOTE: The NC205 is not listed as a fire alarm system. It is not intended as a primary indication means for evacuation.)

“H” = STAFF STATION

This key is used to mark a station as a STAFF station. The stations will be included in staff paging and follow functions.

“I” = MASTER STATION

This key is used to assign a selector button to a master for master-to-master communications. All masters must have the same assigned room number (251-

254) available. Refer to Section 5.3-1.

30 • IL600 NC205 Tek-DIGICARE® Manual

Page 41

To turn off any feature, simply press its associated alpha key so that its LED is off. Widely used programming functions (PRIVACY, PRIORITY UPGRADE, etc.) should be accomplished by use of the master function keys so marked.

C. To program a selector key for master-to-master

communication, press “I” to mark the key as a master. Then press the numerical number of the desired master (1 through 4). All masters must be programmed to have their own selector buttons, in addition to selector buttons representing other masters. For example, if master-to-master communication is desired on a system with only two masters, each master must have one selector button programmed for itself and another selector button programmed for the other master. (Note: 251, 252, 253, 254 are the default keys for master-to-master communication. 251 is used for master #1, 252 for master #2, and so on.)

NOTES: Master-to-master communications are restricted to “push-to-talk” only (no handset). See Section 5.3 for additional details.

Using this method, all master-to-master communications can be programmed at one master. At all other masters, the same buttons are programmed automatically for each master.

5.2-2

Exiting the Programming Mode

To exit the programming mode, press the “RESET” button. The “RESET” LED will flash until the information has been stored.

5.3 MASTER KEY PROGRAMMING/CONFIGURATION

The NC250/NC230 Master Stations provide extended features to allow non-square system configurations, easy keypad expansion, and custom key configurations.

This section explains the methods used to accomplish these functions.

5.3-1 Entering the Programming Mode

NOTE: When erasing the flash memory or adding an expansion keypad, custom configurations (“non-square” and/or “specific selector buttons”) must be reprogrammed. During programming, the fault light may illuminate momentarily–a normal condition.

To place a master station into the programming mode, turn on (down) the programming switch SW4, as shown in Figure

23. The following features are then available:

A. To reset a master station to default values (erase flash

memory), turn SW4 on, toggle SW1, wait for “TALK” LED to light (indicating proper operation) and turn SW4 off.

By default, masters begin room numbering at the first column’s top selector button and continue from top to bottom, left to right, until all keys have been numbered (including all expansion keypads). Other default values include PRESET “A” on, BEEP TONE on, and PRE-ANNOUNCE TONE off.

C. To make a master “non-square”, press the ZONE

button, then key in the numerical value of the room number that the master is to begin from. The TALK LED will flash and a beep tone will sound when the information has been accepted. The programming mode may then be exited.

The term “non-square” means that the master can begin its selector key assignment from a room number other than #1. For example, to program an NC250 master (50 key) to begin responding with room number 15, follow the procedures listed above. Key in “0”, “1”, and “5” for the numerical room value. When completed, the master will respond to rooms 15 (first selector button) through 65 (last selector button).

5.4 EQUIPMENT RESET PROCEDURES

5.4-1 Central Equipment

A. To reset the central equipment, remove batteries and

power down the entire system. Then wait 30 seconds before reapplying power, and reinstall batteries.

B. To reset the flash memory, turn SW1 on and power

down the system per 5.4-1A. Wait until LED’s on the PM261A Selector Card begin to flash, then turn SW1 off.

C. To disable system programming from masters

(programming lock), turn SW2 on.

5.4-2 Master Stations

A. To reset a master, toggle SW1 (see figure 9).

D. To custom configure a specific selector button, press

the target selector button. Using the numerical key column, key in the desired value of the room to which the target selector key will be assigned. The TALK LED will flash and a beep tone will sound when the information has been accepted. The programming mode may then be exited.

The procedure described above can be used to assign individual out of sequence room numbers to a selector button. The same procedure is used to mark a selector button as a master station for master-to-master communication. Room numbers 251, 252, 253, and 254 are reserved for masters #1, #2, #3, and #4 respectively. Do not use these room numbers for any other purposes. (Refer to Section 5.2-1C.)

The NC205 System scans for fault conditions approximately once every six minutes. Faults are displayed through LED’s on master stations, selector cards, and the central equipment.

Faults are displayed on the NC260B by a row of three LED’s, (D1, D2, & D3–from left to right) located at the bottom center of the motherboard. These LED’s will show the detected fault condition via a fault code.

The PM261A Selector Card displays central equipment faults with a single red LED. If the LED is off or steadily on, this will indicate a problem of the central equipment. A flashing LED indicates normal operation. Note: the flashing of this LED is irregular.

A. Master station fault - indicated by LED “D1” on

continuously. Other master stations will light their fault LED’s.

B. Code circuit fault - indicated by LED’s “D1” and

“D2” illuminated. See section 3.3 for indication at master station.

Code faults are displayed at stations with LI387 Dome Lights by a slow flashing blue lamp. Only IR254/ IR255/IR256/IR257/IR258/IR259 stations include code supervision circuitry.

C. Station fault - indicated by LED’s “D1”, “D2”, and

“D3” illuminated. The affected station will be indicated on the master station via lighting the station’s keypad LED and the “FAULT” LED will be continuously illuminated. See section 3.3 for indication at master station. This could also indicate a nurse or priority line fault.

All fault indication which has originated from the central equipment will be indicated by the “FAULT” LED on all master stations being illuminated continuously. The central equipment must then be checked for specific fault indication. The “FAULT” LED flashing at a fast rate will indicate no interrogation from the central equipment for more than eight (8) seconds, indicating a central equipment failure.

To view the fault list, press the master’s “ZONE” button twice. This will display the master’s status information on the first button press; the second button press will display stations that have reported faults since the last central equipment fault scan. They will be indicated by a fast flashing of the station’s selector LED. This display will clear after eight seconds, or when the “RESET” button is pressed.

APPENDIX 1.0 NC260B COMMUNICATIONS MODE

1.1 GENERAL

The NC260B supports bidirectional communications between the Central Equipment and an external communications modem. The connection of the modem to the Central Equipment is accomplished through the use of a built-in RS232 port on the Central Equipment. This RS232 port is the same port that was normally used to support pager and printer operation with the NC260A with the PM263 attached serial port card.

Two additional system features are now accomplished through the use of this port. They are:

A. The ability to program custom room labels, and B. The ability to accomplish limited system fault

location.

The utilization of the new features can be accomplished both locally (at the site) or remotely (from a location other than the site).

Note: If no modem or laptop PC is connected to the serial port or if cable connection to the serial port is incorrect, the system will flash LED “D1” seven times at approximately one flash per half second. If this occurs, the port will be disabled for this type of usage until the system is reset again.

When removing devices connected to the serial port, the system must be powered down prior to removal.

The following section provides detailed operation for the local mode.

A. Connect the prepared null modem cable (Refer to

Figure 24) between the appropriate serial port on the PC or laptop computer and connector J-13 on the NC260B motherboard, then turn on S1-5 and S17 (Refer to Figure 26).

B. Turn on the NC205 system and the PC or laptop and

execute the desired terminal emulator program.

C. After the NC260B system has completed its

initialization and has begun its normal scan cycle (activity LED’s on the selector cards will be blinking and the fault LED’s will not be on), then place switch S1-3 on the NC260B motherboard to ON and then OFF. The microprocessor on the NC260B should stop its normal operation and automatically transfer to the communications mode. Verification that the system has changed modes will be evident in that the LED’s on the selector cards will not be blinking and a Help/Menu screen will be presented on the PC/laptop computer. The NC205 system will remain in this mode unless one of the following items occurs:

1. A “Leave Communications” command is issued from the PC/laptop computer.

2. An automatic “Time Out” occurs due to system inactivity. (Approximately 2-3 minutes.)

3. A system reset to the NC260B is initiated.

1.2 LOCAL OPERATION

To use the NC260B communications mode locally, the following items are required:

A. A PC or laptop computer, and B. A properly prepared null modem cable.

1.4 COMMUNICATION SOFTWARE

There are many software programs that will provide the protocols necessary to accomplish communication with the NC260B. Since most computer operating systems are either Windows 95 or Windows 98, the following section provides the necessary guidance for using Windows supplied HyperTerminal.

1. From Windows start HyperTerminal.

2. When prompted, supply the connection name.

3. Configure the communications port as follows: a. Data Bits – 8 b. Parity – None c. Stop Bit – 1 d. Flow Control – None

4. Click OK.

5. Select File.

6. Select Properties.

7. Select Settings.

8. Set Emulation to ANSI.

9. Set Backscroll buffer to 0.

10. Select ASCII setup.

Make sure that only the two following boxes are selected:

A. Append line feeds to incoming line ends. B. Wrap lines that exceed terminal width. Line delay=0.

Character delay=0.

4. Dial the telephone number that is connected to the NC260B at the site.

5. Upon receipt of the incoming call, the NC260B will answer on the first ring and acknowledge the answer by displaying a HELP screen on the PC or laptop computer. At this point, bidirectional communications are available between the NC260B Central Equipment and the host computer.

6. After the session is completed, the host computer operator will issue a “Leave Communications” command. This command will cause the site modem to disconnect from the NC260B.

APPENDIX 2.0 SYSTEM OPERATION

2.1 GENERAL

The communications feature available on the NC260B is intended to be utilized by technicians familiar with the operation of the NC205 system. All of the user commands

are two characters in length and are text-based.

The general operation in this mode is for the user to enter the desired two-character command at the prompt, followed by a carriage return. If no subsequent parameters are required, the central equipment processor will execute the function. At the completion of the task, the processor will issue a new command prompt. If user supplied parameters, such as room labels, etc., are required, the central equipment processor will issue a parameter prompt (Par->) once the command has been entered. The user must then supply the correctly formatted parameter(s), followed by a carriage return.

In communications mode, the first screen that will be seen on a PC or laptop computer connected to the NC260B is the HELP screen. The HELP screen is designed to provide the user with a list of user commands that can be used to read and write data between the NC260B and the PC or laptop computer. Figure 25 depicts what the HELP screen looks like.

DIAGNOSTIC RC ###, ### READ STTN C CODE RL ###, ### READ LABEL SC ###, P SIMULATE CALL S P D, S, P SET PROTOCOL WC ###, CCCC WRIT E CODE WL ###, CCCCCCCC WRITE LABEL

The two-letter command code shown in the COMMANDS column can be used to perform the listed communications routines between the NC260B and the PC or laptop computer. As an example, if the following key sequence were entered: DH <Enter>, the HELP screen would be displayed on the attached PC or laptop computer. A brief description for each of the COMMANDS shown on the HELP page follows:

A. CS – Clears a simulated system call. (See SC)

B. CV – Displays the voltage on the selected call line.

C. DH – Displays the HELP screen.

(Refer to Figure 25)

ID – Displays the copyright information for the

Central Equipment code as well as the version identifier of the installed code.

F. EC – Toggles the character echo function on and

off.

LI – This command allows the user to review the software license.

H. LC – Used to terminate the communications mode

and restore NC260B system to the normal scan mode.

I. LF – Toggles the line feed issued by the NC260B

ON and OFF.

J. MR – Allows the NC260B processor to return to its

normal scan cycle with the capability of being placed back into the communications mode with a single key press (space bar). If any event occurs while the system is operating in the monitor mode, the status of the event will be displayed at the host computer instead of on the normally attached printer.

K. PD – This command will cause the NC260B to step

through all specified zones and measure the select line voltages. These voltage measurements are made with the select line high and low. If any line fails to indicate the correct voltage, an error will be logged on the PC or laptop computer screen for the failed room. When PD is selected, the user is prompted with two questions. The explanation of these questions is as follows:

1. MAP? (Y or N) –

a. If the operator selects Y, the system will

scan all of the zones that the system found during its initial scan.

b. If the operator selects N, the system will

only scan the zone specified by the user.

2. STEP? (Y or N) –

a. If the operator selects Y, the system will

automatically step through each room on each zone that the system found during its initial scan.

b. If the operator selects N, the operator will

be able to press any key to step from one room to the next.

L. RC –This command reads and displays the pager

cap code assigned to a room. A typical entry for this routine would be:

a. RL <ENTER> b. PAR-> 001,064 <ENTER>

(Where 001 is the starting room number and 064 is the ending room number.)

46 • IL600 NC205 Tek-DIGICARE® Manual

Page 57

M. RL – This command reads and displays the label

assigned to a zone/room and displays the data on the host PC or laptop computer. A typical entry for this routine would be:

a. RL <Enter> b. RRR, QQQ or 101, 005 <Enter> (RRR is the

starting room number and QQQis the quantity of rooms to read.)

SC – This command allows a simulated call to be placed to the Master without actually placing a call from the field. The type of call is selectable. The proper entry for this command is:

a. SC<Enter> b. PAR->###, X <Enter>

(###=Point Number) (X= Priority Code, Fire, Emergency or Routine)

O. SP–This command is used to set the

communications protocol that the NC260B uses to communicate with the PC or laptop computer. This protocol will be applied upon the next system reset, provided S1-5 and S1-6 are set to the “ON” position on the NC260B. If S1-5 is the only switch on the NC260B that is set then the protocol will default to 8,1,N. (i.e. at P> prompt, enter 71E which would result in 7 data bits, 1 stop bit and parity enabled).

P. WC– This command is used to assign pager cap

codes to either room ID’s or zones. Note: The default mode is for all calls to be paged by call type, I.E. all routine calls will go to 401a, all emergency calls will go to 400c and all code calls will go to 400d. The default mode will be disabled if the WC command is used to set cap codes. Resets will be always sent to cap code 402a, regardless of the mode used. When WC is selected the operator is prompted as follows:

been programmed through the “Setup Page By Room” menu will page to the cap code they were assigned to, regardless of how the zones are assigned.

Q. WL– This command allows the user to write labels

to any room attached to the NC260B system. The labels are limited in length to eight (8) characters. The proper entry for this command is:

a. WL <Enter> b. ###,CCCCCCCC (Where ### is the room

number and CCCCCCCCis the desired label for that room).

This function overwrites any previously assigned label, including default labels. When finished entering the desired labels and room numbers, the user exists this routine by depressing the ENTER key.

1. Setup page by room? (Y or N)

a. If the operator selects Y the system

will display the parameter (PAR->) prompt. A typical entry here would be: PAR-> 001,406a <ENTER> This would set selector point number 1 to page to cap code 406a. After <ENTER> is pressed the next point will be displayed, continue programming or press <ENTER>to be returned to the command prompt.

b. If the operator selects N, the message

“Setup Page By Zone?” Will be displayed. A typical entry here would be: PAR-> 002,402b <ENTER> This would set zone number 2 to page to cap code 402b. Note: Any selectors which have

2.2 ERROR CODES AND MESSAGES

Typographical errors, entering the incorrect data, and system faults can cause certain error codes and messages to appear on the PC or laptop computer. The following error codes and explanations are typical:

NOTE:

The following information will be sent to the cap code 402A, regardless of how the system is programmed. This is done so that if an event printer is connected to the serial port, this information will still be printed. Do not use cap code 402A for pagers, unless you desire resets, ETC to appear on pagers.

ERROR CODE EXPLANATION

ER1 Command entered is not recognized

ER2 The parameters that were entered are not in

the proper format or are otherwise invalid.

ER3 The processor has timed out of the

communications mode. (NOTE: Prior to timing out, fault LEDs D1-D3 will begin to cycle. A key press at this point will avert the time out routine.)

ER4 During diagnostic testing, a select line was

not at least mid-scale (~6v) when not selected.

ER5 During diagnostic testing, a select line could

not be pulled down near ground potential.
