- INSTRUCTIONS -
The NEM-EM system provides communication from a central master station to multiple sub stations
(up to 80). A call from a standard room station is annunciated with a steady LED light and an
intermittent tone. An emergency call from a bathroom pull cord (NBR-7AS) is annunciated with a
flashing LED light and buzzer tone. A standard call can be reset at the master station. An emergency
call must be reset at the bathroom pull cord location.

IMPORTANT NOTES:
1. When wiring NA-A or NA-AN to NBR-7AS,
install diode (1N4001~4007) as shown above.
2. If no corridor lamp is included with NA-A/AN,
leave jumper between D and E attached.
3. If corridor lamp is installed with NA-NE or NB-L,
separate Green and Black wires, and connect
Blue and Black wires together.

OPERATION:
1. When the sub station in a room places a call, the red channel LED indicator lights steady and
the standard call tone rings at the master. The tone and light will remain activated until the
call is answered. The LED indicator at the sub station will be lit from the time the call is
placed until it is answered. If a corridor lamp is included, it will light up and remain on until
the call is answered.
2. If the master station is talking to another sub station, a new call will light the LED, but the call
tone will not be heard.
3. When an Emergency call from the NBR-7AS is placed, the master station's LED indicator will
flash, a buzzer tone will be heard, and the corridor lamp outside the room (NBY-4A/EM) will
flash. The call signal will continue until the master answers or the call is manually reset at the
NBR-7AS.
4. When the call is answered, the LED on the master goes off. The person at the master uses
the push-to-talk, release-to-listen button, or picks up the handset to speak (with NEM-A
masters). The LED at the sub station will go off when the master answers.
5. When the conversation is completed, the OFF button to the left of the station selector button
must be pressed to disengage the call.
6. If the master station answers an emergency call, communication will be the same as above,
but when the OFF button is pressed, the call-in signal will return. An attendant must go to the
room that placed the call and physically reset the call.
