Description
The LEF-3L is a compact 3-call master intercom station designed for seamless communication with up to three other stations. It offers the capability to selectively release doors and manage external security devices. This versatile intercom system can also activate CCTV cameras, lighting systems, or other connected devices using a relay mechanism triggered upon selection of a communication channel. The master intercom station features a convenient door release button to operate electric strikes or magnetic locks. To integrate each external device, a relay (RY-PA) is essential, allowing for either momentary or sustained closure. The RY-PA relay provides a “normally open” output configuration, which can be adjusted to “normally closed” as needed in security and automation applications.
