TekTone PK543A Apartment Intercom Amplifier for 5, 4, Wire Remote Station

Reliable, self-contained amplification and control for apartment entry security and monitoring. The TekTone PK543A Apartment Intercom Amplifier is engineered to streamline intercom installations by providing all required amplification, control and power circuits in one compact surface-mount unit. It supports 3-, 4- or 5-wire remote stations and offers front-panel screwdriver access to voice and tone volume, letting technicians make fast field adjustments without opening the cabinet.

Designed for property managers, security integrators and building technicians, the PK543A includes selectable door timing modes for AC, DC or Maglock configurations, post-office door release, steady or warble call tones and a visible power LED for status checks. The unit’s compact footprint (approximately 5.5" x 3.1" x 2") and flame-resistant housing make it ideal for risers and entry panels in multifamily or light-commercial settings. Integrate with PK502B for multiple-entrance setups and use the optional talk-before-door interlock on 4-wire stations for added access control.
