Reliable, Versatile Security

The Inovonics EchoStream Four Zone Add-On Receiver with Relay Outputs programs and supervises up to four Inovonics transmitters in your security system. Relay outputs provide versatility by allowing connection to any hardwire panel or stand-alone wireless application. With diversity reception and advanced signal processing, Inovonics Wireless EchoStream technology minimizes dead spots in transmission areas. The receiver can also be fully supervised when registered with your system.

  • Add up to four EchoStream wireless transmitters to any installation
  • LED indicators signal the current status of all four transmitters
  • Five Form C relays connect any panel: four alarm, one fault
  • Case tamper protection, jam detection, and internal antennas secure wireless implementation
  • Outputs can be configured in follower, latching, momentary, or toggle modes independently
  • Built-in wireless programming routine


  • Add-on receiver
  • Installation anchors and screws

Inovonics Wireless: Developed For Commercial Applications

The Inovonics Commercial Mesh Network has been specifically developed for commercial applications to provide the most cost-effective solution for a wide range of applications, while setting new standards for performance and reliability in a wireless sensor network.

Reliability: Inovonics EchoStream 900MHz radio utilizes a unique frequency hopping, spread spectrum technology to meet the demands of an increasingly cluttered wireless world.

Flexibility: The flexibility of wireless is a necessity in today's dynamic commercial environments. The self-configuring EchoStream Commercial Mesh Network allows you to adapt to changing floor plans and requirements in a matter of minutes. New sensors can be added to the network as fast as they can be mounted.

Scalability: The EchoStream Commercial Mesh Network's backbone of intelligent repeaters can extend coverage to thousands of sensors across entire commercial campuses.
