Three Call Master Station and One Substation

Easily communicate with this Master-to-Substation Intercom System. Designed for simplicity and reliability, this kit includes everything you need to get started: one Master Station, one Substation, and a power supply.

Key Features:

• Individual Substation Calls: The Master Station features three buttons, each dedicated to calling a specific Substation. Easily expand your system with up to two additional Substations.
• Discreet Monitoring: Monitor the area around any Substation by pressing its corresponding button. To end monitoring, simply press the Off button. While monitoring, incoming audible calls from other Substations are muted, but an LED indicator provides a visual alert.
• Hands-Free Communication: Substations allow hands-free talking once the Master responds. The Master uses a press-to-talk mechanism for seamless interaction.
• User-Friendly Controls: Adjust call tone and voice volume as needed for clear and efficient communication.

Simple Operation:

• Substations call the Master by pressing the Call button, which triggers a tone.
• The Master can call a Substation by selecting its button, then pressing the Call button to ring. Conversations begin by pressing the Talk button at the Master.
• Communication is secure; Substations cannot communicate with one another.

Easy Installation:

Only two-conductor wiring is required between the Master and each Substation, ensuring a straightforward setup. Substations cannot share wiring, and the system supports wiring distances up to 1,570 feet with 18AWG wire. Shielded wire is recommended for noise-free operation.
