The models listed above have been modified to allow the Blue Call button (NHR-7A-CB) to activate the highest
priority call on the NHX Nurse Call System. When the Blue switch is pushed down to the lower position, the master
station will indicate the call with a fast intermittent call tone and flashing LED. The call can be cancelled only by
raising the switch to the upper position. All other call levels remain the same.

Models:
• NHR-7A-CB1: standard unit (SPST)
• *NHR-7A-CB2: Includes second dry
contact closure (DPDT)

OPERATIONS:
The NHX system with CODE BLUE has three priority levels:
Priority 1: Code Blue
Priority 2: Bath call and cord-out
Priority 3: Routine call
1. Code Blue call signal is a fast beep (1 per 0.5 seconds) and flashing LED (1 per 0.4 seconds).
This signal is activated when the blue call switch on the NHR-7A-CB1 is moved to the lower
position, and will continue until it's reset to the upper position.
2. The Bath/Cord out signal is a single beep (1 per 2 seconds) and a double-blinking LED (2 blinks
every 1.8 seconds). This signal is activated when the bath pull cord (NHR-7A) is moved to the
lower position, or when the handheld call button (NHR-8A) is pulled out of the station. The call
signal will remain until the master answers the call, at which time the tone will be reset. The
blinking LED will remain until the bath station is reset to the upper position or the handheld call
button is plugged back into the station.
3. The Routine call signal is a single beep (1 per 6 seconds) and a blinking LED (1 per 2 seconds).
This signal is activated when the button is pressed on the handheld call cord, and is reset when
the master station answers the call or when the CANCEL button on the patient station is
pressed.
4. To place a CODE BLUE CALL, activate the Code Blue Station located near the patient station by
pulling the attached cord or sliding the blue call switch down.
5. To reset the CODE BLUE CALL, move the blue call switch to the upper position.
