NHR-4A
Dual Bulb
Corridor Lamp
NHX Nurse Center
DESCRIPTION:
The NHR-4A Dual Bulb Corridor Lamp for the
CommuniCare system provides light
annunciation outside of a patient room when a
call has been placed from either the bedside
call cord or bathroom pullcord in that room.
Mounted into a standard 1-gang box, the
corridor lamp displays a white lamp for a bedside
call and a red lamp for a bathroom call.
OPERATION:
A call from a bedside call cord attached to a
patient station will steadily illuminate the white
lamp. Light will be turned off when the master
station answers the call, or when the CANCEL
button is pressed on the patient station.
A call placed from the bathroom pull cord will
activate a flashing red lamp, and will be turned
off only when the call is reset at the bath station.
If the bedside call cord is removed from the
patient station, the white lamp will flash, and
will be turned off when the call cord is reinserted
into the jack.
FEATURES:
• White lamp for bedside call
• Red lamp for bathroom call
• Single-gang mounting
• Easy wiring to patient station
