Key Features

• Complete Kit – Includes power supply for hassle-free installation.
• Enhanced Door Control – Equipped with a door release button for easy access management.
• Flexible Mounting Options – Can be wall-mounted or placed on a desktop.
• Simple Wiring – Uses a 2-conductor shielded wire for easy connection between substation and master station.
• Long Wiring Distance – Supports up to 650 feet with 22AWG wire and 1,570 feet with 18AWG wire.
• Reliable Communication – Press-to-talk, release-to-listen at the master station, while the substation operates hands-free.
• Supports Multiple Masters – Can connect up to four master stations to a single door station.

Operation Guidelines

• Only one master station can be used at a time.
• If both masters are activated simultaneously, system feedback (squealing sound) may occur.
• To eliminate feedback, press the OFF button on one of the master stations.

Installation Instructions

• Wiring: Use a 2-conductor shielded wire from the door station to the first master, then to the second master.
• Door Release Wiring: If using door release functionality, a separate 2-conductor wire must be connected from the master station’s "EL" terminals through an AC transformer to the door strike.
• The door release button provides a "Normally Open" (N/O) dry contact closure for secure access control.
