Functions

Alarm function from discrete signals

  • Annunciator device for operation from NO or NC contacts.
  • Adjustable time delay.
  • LED-indication of each alarm channel.
  • Collecting signals from output contacts of relay protection and automation devices.
  • Alarm and warning signals receiveing with adjustable time delay, ensuring action repetition and visual (light) indication;
  • Receiving signals of the position of switching devices with visual (light) indication;
  • Receiving signals from auxiliary signaling buses with ensuring repeatability, visual (light) indication and diagnostics of auxiliary buses.

Group Alarm Functions

  • Receiving signals from signaling buses, in response to a sudden current changing, ensuring repetition of action, visual (light) indication.
  • Compatible with a wide range of typical configurations of supervision alarm auxiliaries.

Alarm reset functions

  • Local and remote alarm reset.

Functions for controlling external sound devices, etc.

  • Sound alarm control separately for alarm and warning circuits with the possibility of automatic reset with time delay.
  • Group and extended alarm signals, apart for emergency and warning alarms.
  • Critical and warning audible alarms separation.
  • Adjustable audible alarm length.

Registration function

  • Event reporting.
  • Nonvolatile memory of events logs and device settings.
  • Serial data transfer interface.
