Alarm Sequences
The ISA 18.1 Standard is a standard for electrical announcers that indicate abnormal process conditions using individually illuminated visual displays and audio devices.
This standard has been prepared to determine the announcer terminology, sequence definitions and sequence presentation and to assist in the preparation of announcer features and documentation.
Below you can see the order of operation and their logic in accordance with the standard. Telepro Alarm Announcements comply with these standards.
