Aiphone LEF-LD Instructions

LEF Loudspeaker Intercom System for Long Distance and Elevator Applications
LEF-3-LD, LEF-3L-LD, LEF-5-LD, LEF-10-LD, LEF-10S-LD
The LEF-LD system is designed with the capability to operate at greater distances and for use in
elevators. The sub stations are available in either surface or flush mount styles. Any LEF, LAF-C/CA, or
LDF master can be modified for Long Distance. This is a SINGLE MASTER SYSTEM ONLY. EXTERNAL
SIGNALING WITH THE RY-AC/A RELAY IS NOT SUPPORTED ON THIS SYSTEM.
IMPORTANT:
Only the IF-DA-LD, IE-JA-LD, IE-SS-LD and IE-SSR-LD will function with these "LD" type master stations. Standard
LE- or LS-series sub stations cannot be used with LEF-LD master stations. In addition, the remote stations listed
above will only function with the "LEF-LD, LAF-LD or LDF-LD" model master stations.
