LEF-5-NE/LEW-5-NE
5-call Master Station
Master Station for use with the NEM and NDR Systems
- INSTRUCTIONS -
The LEF-5-NE is a 5-station master, equipped with a door release button, and able to integrate into a larger
NEM or NDR system. In applications where up to 5 door stations needs to be answered from the main NEM/
NDR master as well as additional small master stations, the LEF-5-NE can be used. The LEW-5-NE adaptor
is required. This system can be used with the following subs: NE-DA, NE-JA, NE-SS/SSR, NE-NVP/C,
NE-NVP-2DC-LE, NE-NVP-RA.

NOTE: Standard LE-series sub stations cannot be used
in a system with the LEF-5-NE master stations. The LED
timing circuit in the LEF is modified.
The NA-A and NA-AN also cannot be used to call the
LEF-5-NE, but can be connected directly to the NDR/
NDRM master station.
"K" Terminal connections
are required in this
application, with or without
door release being included.

OPERATION:
1. Pressing the call button at the door/sub station will activate the call tone, plus light the
appropriate station LED at the NEM/NDR master. The call tone will be heard at the LEF-5-NE
master(s) continually until the call is answered from any master in the system.
2. To answer the call on the LEF or NEM/NDR master, press the station button corresponding to
the lit LED, then press TALK to speak to the visitor. When the first master answers the call,
the Occupied lamp will be lit on all other masters. DO NOT answer the call if the Occupied
lamp is lit.
3. Communication at the master station is "press-to-talk, release-to-listen". Communication at
the door station is hands free.
4. With communication established to the door station, pressing the door release button will
activate the door release mechanism at the corresponding door.
5. When the call is completed, press OFF on the LEF master, or the associated black OFF
button on the NEM/NDR master. The Occupied lamp will go out on all masters when the call
is cancelled.
