Description
The Notifier AEM-24AT Annunciator Expander Module is designed to enhance the capacity of your ACM-24AT LED annunciator by adding 24 additional programmable system points. Supporting up to three AEM-24AT modules per ACM-24AT, the system can be expanded to a total of 96 annunciation points, offering scalable flexibility for larger fire alarm installations.
Each AEM-24AT module maintains the same physical dimensions and front appearance as the base ACM-24AT, allowing for a consistent, professional look across your annunciation system. This expander module supports various annunciation configurations, including Alarm/Circuit-On and Trouble LED per-point, or a denser Alarm-only option, depending on your system’s needs.
The AEM-24AT is part of the Notifier ACS Series, which offers modular, remote LED annunciation and control for Notifier and FireLite fire alarm panels. When connected, the expander communicates via a serial interface and may be installed up to 6,000 feet (1,828 meters) away from the main panel.
It also supports custom labelling, color-programmable LEDs, and plug-in terminal blocks for streamlined installation and servicing. Whether you’re building a new fire alarm system or expanding an existing one, the AEM-24AT provides a reliable, cost-effective way to improve point visibility and status control across your site.
