Patient Stations
Single and Dual Patient Stations for All Call,
and when sharing a common Corridor Lamp
- INSTRUCTIONS -
Some applications for Nurse Call systems require All Call. By including the NH-50AC adaptor and the "AC" model
patient stations, a station button on the master can be used to call all of the patient stations simultaneously. An
additional wire is required to each patient station. In addition, if there is more than one patient station sharing a
corridor lamp, this model patient station will allow that configuration to be used.
NOTE: An NHX system installed with an NH-1SA-AC or NH-2SA-AC included does not carry the UL 1069 listing.
