The NE-DA is a weather resistant door station designed for use with the NEM, NDR, or NDRM systems.  
The unit is equipped with an option for an external output contact closure when the sub station places a 
call (relay required). The NE-DA is weather resistant and surface mounts on a 1-gang box.

NOTES:
1.  The NE-DA can have the external closer option, the corridor lamp, or both connected.
2.  If the extra contact closure or corridor lamp option is not being used, do not connect the blue or
     purple wires.  Trim them back to prevent a short on the wires.
3.  When using the extra contact, connect input (coil) of relay to the H of the master and PURPLE wire
     at the sub.
4.  The dry closure will stay activated from the time the call is placed until it is answered at the master
     station.  The RY-PA is a 12V DC, “Normally Open” relay.  If a “Normally Closed” contact is required, 
     the RY-PA can be changed to N/C, or a standard 12V DC, N/C relay can be used.

OPERATION:
1.  To place a call, press call button on door station once.  The call-in tone and LED will be lit on
     the master station, remaining activated until answered.  The LED on the door station will be 
     lit to indicate a call has been placed.
2.  When the master station answers, a brief pretone will be heard.  Speak into the door station
     hands free.
3.  When the call is completed, the person at the master will press the OFF button and
     communication will be cut off.  The person at the remote station does nothing.
4.  If a corridor lamp is included, the lamp will be lit from the time the call is placed until it is
     answered.
5.  If a relay is included at the remote station to provide an extra dry closure, the closure will be
     activated from the time the call is placed until it is answered.  This extra contact can be wired
     to an alarm device, or to a CCTV switcher to activate a camera.   
6.  When using this system for camera call-up and if the camera is to remain activated during
     communication with a remote station, use the NDR or NDRM master station in place of the
     standard NEM master station.  The NDR/NDRM provides selective outputs for camera 
     control.
