E. Wall-Mounted Component Connection Method: Components connect to system wiring in back boxes with factory-wired plug connectors.

2.3 FUNCTIONAL PERFORMANCE

A. Pull-Cord Station Call: Flashes a call-placed lamp on the station and distinctive-color lamps in the zone light and corridor dome light and at the central annunciator and staff and duty stations.

At the same time, it sounds a distinctive tone at intervals, at the central annunciator and master, staff, and duty stations. A legend at the master station identifies the calling station.

B. System Reset: Operating reset button at the originating station cancels signals associated with the call.

C. Cord-Set Removal: A patient station call is initiated when the cord set is removed from the jack in the patient station faceplate. Inserting a cord-set plug or a dummy plug into the jack and operating the station reset button reset the call.

D. Pocket pagers: A call can be initiated from the Master station and sent to the assigned pocket pager.

E. Station Selection: Master station is capable of selectively communicating with other stations, groups of stations or pocket pagers on its system by operating selector switches.

F. Master Station Privacy: Capable of conversing with individual stations in complete privacy.

NURSE CALL/CODE BLUE SYSTEMS 275223 - 4

G. Hands Free: Called station is capable of conversing hands free.

H. Annunciation: At the master station, a tone announces an incoming call and an annunciator light or liquid-crystal display identifies the calling station and indicates the priority of the call.

Memory lamps or lighted displays identify stations selected for outgoing calls.

I. System Reset at Master Station: A normal incoming call is canceled, associated lights and audible tones are extinguished, and the system is reset when the station switch is returned to the normal position after responding to a call.

J. Patient Station Call: Lights the call-placed lamp at patient station, zone, and corridor dome lights. It sounds a tone and lights the call lights at staff/duty stations and actuates annunciation at the master station. When the calling station is selected at the master station, the patient can converse with the master station without moving and without raising or directing the voice.

K. Pull-Cord Call Station and Emergency-Call Station Call: Lights call-placed lamp and corridor dome light, and flashes zone light. Master station tone pulses and annunciator light for that room flashes. When master station acknowledges the call by operating a switch, the tone stops but lights continue to flash until the call is canceled at the point of origin.

L. Code Blue, Staff, and Duty Station Call: Lights the call-placed lamp at the station and actuates annunciation at the master station. When the called station is selected at the master station, the caller and the master station operator can converse.

1. Code Blue: Unique sound and light pattern, indicating the highest priority emergency.

2. Staff Station: Unique sound and light pattern, indicating an emergency.

3. Duty Station: Sound and light pattern, indicating a call to the nurse station.

M. Handset Operation: Lifting handset on master station disconnects speaker microphone and transfers conversation to the handset.

N. Station Privacy: No patient, staff, or duty station can be remotely monitored without the lighting of a warning lamp at the monitored station.

O. Patient Station Cord Set: When a patient station cord-set plug is removed from the jack in the station faceplate, a patient station call is initiated as described above. When the master station call button for the station is pressed, the tone stops but lights continue to flash until the call is canceled at the point of origin or the plug is reinserted or replaced with a dummy plug.

P. Patient Control Unit: Speaker is used for nurse communication. Nurse button on the unit initiates a patient station call.

Q. Selective Paging: Master station is capable of initiating a message through wired and wireless connected devices, to selected groups of stations, speakers or pocket pagers simultaneously by using station group switches.

R. Staff Reminder: Master station can initiate a staff reminder that a patient requires direct staff response by operating a reminder control while in contact with the patient station. This will light a distinctive-color lamp in the corridor dome light at the patient's room and in the appropriate zone lights. Reminder calls are canceled by operating a staff reminder cancel switch in the patient's room.

NURSE CALL/CODE BLUE SYSTEMS 275223 - 5

S. Call Priority Indication: Call priority switch near each patient station, or integral with the master station, controls the priority status of the call transmitted by individual stations. The switch selects one of the following status levels:

1. Normal: No change to the normal call initiation and canceling sequence.

2. Emergency: Call initiation produces signals and indications identical to those of emergency-call stations. Indicator lamps are extinguished and the system is reset only at the originating station.

3. Priority: System response is the same for emergency status, except voice communication between the master station and the calling station is locked in from the time of call initiation until the system is reset at the originating station.
