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.

WIRING:
1. Follow the wiring diagram on front page of these instructions.
2. Connect the corridor lamp wires (Brn, Red, Org) to the same colored wires on CN2 of BOTH
the patient stations in the room. Otherwise, the corridor lamp will not light up when either
patient station places a call.
3. Connect the bathroom station (Yel, Grn, Blu) to the same colored wires on CN2 of JUST ONE
of the patient stations in the room. The bath station for that room will annunciate on the same
position at the master as the station it is wired to.
4. If All Call is not included, do not connect the BLK wire from the patient station.
5. If a Zone Light (NHR-3A-4) is not included in the system, do not connect the VIO wire on CN2.
OPERATION:
1. A call from any of the the handheld call buttons on either station in the room will light on the
master station, and the corridor lamp will light the white lamp steadily.
2. A call from the bath station will light on the master at the station it is wired to, and will flash the
corresponding corridor lamp's red bulb. Bathroom switch must be moved upward to reset the
call.
3. A cord-out call from any station in the room will flash the white bulb. Cord must be reinstalled
in the jack to cancel the call.
