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

Put secure, coordinated access control at the heart of your site with the Aiphone LEF-3L intercom master station. Designed for commercial and institutional environments, this 3-call master station gives operators one-touch control over three remote stations and selective door release to quickly clear visitors or grant entry. The LEF-3L uses 12V DC low-voltage power and supports relay-controlled activation (RY-PA required) so you can trigger electric strikes, magnetic locks, CCTV cameras or lighting from the master when a channel is selected.

Beyond basic audio, the LEF-3L improves monitoring and incident response: push-to-talk at the master with hands-free reply at remotes reduces transmission delays, while ABS housing and compact dimensions make it easy to mount at a desk, wall or counter. Intermixable with other LE-series components and compliant with TAA/NDAA, it’s a practical choice for secure facilities, retail stores, hotels and government sites. Enhance your site’s security and surveillance workflow with dependable, wired intercom control—contact us to specify the LEF-3L for your next access control or monitoring project.
