Echo Contact Interfaces

Echo Contact Interfaces are DIN rail mounted devices that are available in four input or four output configurations.

  • Input Interface - accepts four momentary or maintained closures to trigger control actions within an Echo system.
  • Output Interface - provides four normally open or normally closed output relays controlled by actions in the Echo system.

Echo Contact Interfaces have a front panel configuration mode switch which allows selection between Basic and Custom configurations of the Contact Interface. Configuration settings done in the EchoAccess™ Mobile App will not take effect unless the switch is set to Custom configuration. See the Unison Echo® Contact Interfaces Installation Guide for information about the default behaviors of Echo Contact Interfaces in Basic and Custom configuration.

Echo Contact Interfaces have front panel rotary switches that select Space and Address/Zone. See the Unison Echo® Contact Interfaces Installation Guide for more information on default settings.
