The Honeywell Annunciator module is a part of the Honeywell SLATE integrated combustion management system.
The annunciator module monitors the status of the interlock string (the built in safeties). This module can detect when and where there is a problem in the SLATE system. When the annunciator module detects a problem it will then send an alert stating what the problem is. This alert can be found on the Honeywell touchscreen display or the Honeywell Generic Webpage.
