The Aiphone LEF-LD System is designed with the capability to operate at greater distances and for use in elevators. This two-way communication system is designed with the capability to operate at distances up to 4,000’ away from the master station or located in elevators. The remote stations can call to master with a momentary electronic tone and a LED that remains lit for 20 seconds. The press-to-talk communication at the master makes it hands free at remote station. The system can have from 11 to 80 stations with LAF-C/CA-LD system and is available in 3, 5 and 10 station sizes. The sub stations are available in either surface or flush mount styles and each remote uses a simple 3 conductors wiring. Any LEF, LAF-C/CA, or LDF master station can be modified for Long Distance.
