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.
