Aiphone LEF-5 5 Call Wall Mount Audio Master Station

The master station can selectively call and communicate with any station in the system. Communication is press-to-talk at the master, with hands-free response at the receiving sub station. The privacy button prevents the master from monitoring a sub station until the function is disengaged, ensuring confidentiality where required.

The LEF-5 features a station selector switch, selective monitoring and door release functionality. It is compatible with LE-A, LE-D, LE-DA and LS series sub and door stations. The system requires a PS-1225UL power supply, which is not included and must be ordered separately. Wiring between master stations uses 822212 cable (12 conductor, 22 AWG, shielded) with a maximum distance of 650 ft. Wiring to door stations uses 822203 cable (3 conductor, 22 AWG, shielded).
