LEF-3L LEF Series 3-Call Master Station with Selective Door Release

The LEF-3L is a compact 3-call master station designed for internal communication across multiple stations while providing selective door release and external device control. Built with durable ABS plastic housing, it supports push-to-talk communication at the master station with hands-free reply capability at called stations. This versatile system accommodates up to four intermixable stations—combining any number of LEF master stations and LE door stations. The integrated door release button activates electric strikes or magnetic locks, while optional RY-PA relay modules enable control of CCTV cameras, lights, and other external devices. Each relay can be configured for momentary closure (while the button is pressed) or maintained closure (while the station is selected), with switchable "normally open" or "normally closed" outputs. Compatible with the entire LE-series component lineup, the LEF-3L integrates seamlessly into existing systems. For enhanced durability in outdoor or high-traffic environments, pair it with the vandal-proof, weather-resistant LS-NVP/B remote station.
