LEE DAN PK-543A 5-4-3 Wire Apartment Intercom Amplifier

The LEE DAN PK-543A intercom amplifier delivers reliable, self-contained power and amplification for multi-unit entry systems, making it an ideal choice for property managers, integrators and security professionals. Designed for compatibility with 3-, 4- and 5-wire apartment stations, this compact surface-mount unit (approx. 5.5" x 3.1" x 2") supports voice and tone volume adjustments from the front panel so tenants get clear communication without onsite tweaking. Selectable AC or DC door operation and a configurable delayed-action door release give installers the flexibility to match a variety of door strikes and access control setups. Additional features include multi-entrance operation capability and steady/warble tone options for distinct entry signaling—useful in busy apartment, condo or mixed-use properties that require reliable access monitoring. Because the PK-543A is interchangeable with TekTone PK543A models, it’s a straightforward drop-in replacement for existing intercom and surveillance-linked entry systems. Enhance your building’s security and tenant experience—specify the PK-543A for your next intercom or entry control project.
