Description
Fire Detection, Control Panels and System Accessories
The AEM-24AT-AUS Annunciator Expander Module is an expansion accessory designed to increase the annunciation and control capacity of the Honeywell NOTIFIER ACM-24AT-AUS Annunciator Control Module. It provides an additional 24 programmable points, allowing larger fire alarm systems to display and manage more zones, events, and system functions from a single remote annunciator assembly.
The AEM-24AT-AUS adds 24 additional tri-colour status indicators and 24 dedicated fault indicators, matching the functionality of the ACM-24AT-AUS and providing clear visual identification of system conditions. The expander module connects directly to the ACM-24AT-AUS and does not operate as a standalone annunciator.
Up to three AEM-24AT-AUS expansion modules can be connected to a single ACM-24AT-AUS, increasing the total annunciation and control capacity from 24 points to a maximum of 96 points. This scalable design makes the AEM-24AT-AUS suitable for large commercial, industrial, healthcare, education, and infrastructure fire alarm installations.
The module provides a neat and integrated solution for expanding remote annunciator assemblies while maintaining consistent LED indication, system status visibility, and operator interface functionality.
