1 SYSTEM OUTLINE & COMPONENTS

The NHX is a Health Care Communication System, exclusively designed for patient to staff communications in health care facilities. The NHX system is UL Listed under UL1069 the Standard for Hospital Signalling & Nurse Call Equipment. At Nurses Center, the NHX-50M master station is an extremely compact, low profile console. Add-on 30-call selector can be plugged into NHX-50M. In each room, single or dual-call Nurse Call bedside sub stations are used with corridor light and bathroom call switch. The NHR-3TS is a common area or hallway sub station, which can be used with a NHR-7A pullcord urgent call switch.

 Mounting location

NHX equipment is designed for indoor use only. NHX-80X must be wall-mounted on a UL Listed 3-gang box or in a Listed electrical enclosure. The enclosure should be provided with a solid noncombustible mounting plate board for securing the NHX-80X chassis. ( Ref. NHX-80X dimensions: 460H x 340W x 98D. 18-1/8"H x 13-3/8"W x 3-7/8"D). Locate the NHX-50M master within close proximity of the NHX-80X CCU. (Max. 20m, 65' wiring distance)

 Wiring

1. Use Aiphone specified shielded cable. Otherwise, run wires in metal conduit to prevent any malfunction or noise interference.

2. CAUTION: – Risk of Electric Shock When installing, route field wiring away from sharp projections, corners, and internal components.

 Cable

For wiring between NHX-80X, NHX-50M, and sub stations, use UL Listed twisted pair cable, only copper conductors, 22AWG min. or heavier, rated 300V. Cable to call buttons and lamps can be either parallel or twisted pair cable, 22AWG or heavier, UL Listed.

 Power supply

For NHX-80X CCU, use the power supply exclusively designed, as listed below;

• PS-24E or PS-2420: Rated input 120V AC, 50/60Hz. Rated output: DC 24V, 2A (Requires two units per

system). For Zone light Model NHR-3A-4 (max. 4 per system), install a PS-24E or PS-2420 power supply for every 2 Zone lights.

 Power off system resetting

When NHX system malfunctions, turn NHX-80X power switch off and on again, and entire system will be reinitialized. The reset switch on NHX-80X is used when initializing NHX-80X for sub stations. The reset switch on NHX-50M is used when checking connection of sub stations.

 Zone light installation

Zone light will indicate which zone has a call placed at one to max. 4 locations in the facility.

• Permitted distance: 165’ with 18AWG (50m with 1.0mmø) from the NHX-80X.

 Initializing NHX-80X for Sub stations

The NHX-80X CCU must be set to zero after all the sub station numbers are programmed. Proceed as follows;

1. Remove the switch cover on front cover. Place the dip switch SW2-2(SET) to upper ON position. The rest dip switches must remain in OFF position.

2. Make sure sub stations are all in standby. If a sub is not in standby mode, it cannot be acknowledged properly.

3. Turn power switch on NHX-80X ON.

4. Press RESET switch. LED 1 blinks green.

5. LED13 blinks green for 5 seconds, and goes out.

6. Place the dip switch SW2-2(SET) back to OFF position.

7. Press RESET switch again. Programming for subs is complete. All the switches must be in OFF position. LED13 starts blinking. See the status of four LED’s as above.

 Checking Status of Sub stations on NHX-50M (Testing)

Test the NHX-50M to visually check status of all sub stations:

• On the bottom of the NHX-50M, press RESET button while holding down OFF button on front panel.

The NHX-50M enters testing mode. Check the sub stations throughout system as follows: From sub 1 of the first row, the LED is lit and goes out if the sub is connected. Then, the LED of sub 2 is lit and goes out. All subs are scanned in this way to check sub’s status. If a sub is not connected, the LED is lit and remains on.

• If a sub is connected but the LED won’t go out, check status of the sub station as follows: (1) Incorrect programming (2) Not placed in standby with bathroom call (3) Incorrect wire terminations

• On the subs(s), which have been found yet not programmed in testing mode, check number

programming. Repeat process from Step 4 of the above section.

• To get out of testing mode, press OFF button on NHX-50M.

Multi-Station Patient Room Applications

Multiple NH-1SA/A and NH-2SA/A bedside sub stations can also be installed within a patient room. Observe the following conditions;

• Max. 6 bedside sub stations may be connected per room for max. 12 calls (when NH-2SA/A stations are used).

• A corridor lamp inside (NHR-4A) must not be connected with more than 4 bedside sub stations.

• Due to the above, install two NHR-4A corridor lamps when more than 4 sub stations are in one room, i.e. two WHITE lamps used in one NHR-4A, and one RED bulb used in the other NHR-4A.

• NH-1SA/A and NH-2SA/A station numbers must be programmed in numerical order and connected to the same subs trunk line.

• NHR-7A bathroom pullcord is optional.

RESET switch

Do not use RESET switch except for initializing or testing the NHX-80X. If RESET is pressed while a call is being placed or a Bathroom call or Cord-out trouble call has been placed, it will suspend the call.

* Do not press RESET switch except when installing, changing subs, or when system malfunctions.

Adjusting Preset Volumes

On the bottom of the NHX-50M, adjust volume controls to desired level.

* TRANSMIT: Adjusts the NHX-50M’s voice heard at

bedside sub.

* RECEIVE: Adjusts the speaker volume on NHX-50M.

Adjustable 3-position control on the left panel.

• PRE-TONE: Adjusts pre-tone to the desired level heard at bedside sub.

• TONE: Adjusts initial call tone level. 3-position switch varies volume from preset level (user-adjustable).

• DUTY STATION: Adjusts call tone level heard at Duty Station

When System Malfunctions;

Call tone sounds on the NHX-50M without being called. Call-in LED is lit, but no call tone. In such occasions, check the status of system, and turn power switch off and on again at the NHX-80X. If the system does not return to normal operation, turn OFF power switch and contact your installing dealer or Aiphone.

Call priority:

1. Cord-out trouble call

2. Bathroom call, or NHR-3TS common area

bathroom call or staff call (urgent call),

3. Routine call

In Standby mode;

Priority is put in the order of Cord-out trouble call, Bathroom call and Routine call. Cord-out trouble call is put in first priority, and overrides any other calls on the system.

During communication; The NHX-50M master station sounds an incoming call tone while talking to another station, the same as in standby mode. A new call doesn’t override an existing conversation. Reply after concluding current call.

Up to 5 sub call-ins can be displayed on the selector switch bank. All the calls placed are held in a queue, and will resume light and tone at NHX-50M after each previous call is concluded. Momentarily hang up handset, and the next call tone is audible. The sixth call will not illuminate on NHX-50M nor on Corridor lamp (Only zone light will be lit).

The NHX-50M is capable of having as many calls held as there are sub stations. To reply to next call, hang up and lift handset or press TALK button to establish channel.

• If calls are of the same level; in the order of time of call,

• If calls are of different levels; in the order of urgency.

Operational Modes in Multi-Station Patient Room application
