Indoor Surface Mount Substation

Easily expand your 2-wire master intercom system with one or more additional indoor substations. Designed for simple and efficient communication, this substation allows users to call the master station with a single press of the Call button, activating a tone that sounds as long as the button is held. Once the master station operator responds, the substation enables hands-free communication, while the master user presses the Talk button to reply.

This substation integrates with the master system, requiring only two-conductor shielded wiring for a straightforward installation. Each substation operates independently and cannot share wiring with other substations. Best of all, no additional power supply is needed, making expansion hassle-free.
