Aiphone LEF-3L is a compact 3-call master station that talks with up to three other stations and can selectively release doors and control external devices. A relay triggered when a channel is selected can switch CCTV cameras, lights or other devices, and a door release button operates electric strikes or magnetic locks.
Masters and remotes can be intermixed up to four stations in total. The calling master uses press-to-talk, and the responding station answers hands-free. Each external device needs an RY-PA relay, set for a momentary closure while the key button is pressed or a maintained closure while the station is selected.
