Notifier ACM-24AT is an ONYX Series ACS annunciator control module with 24 annunciation and control points. Each point has a color-programmable (red, green or yellow) Active LED, a yellow Trouble LED and a momentary touch-pad switch. The module also has a System Trouble LED, an On-Line/Power LED and a local piezo sounder with a silence/acknowledge switch for audible indication of alarm and trouble conditions.
The ACM-24AT annunciates and controls points on Notifier ONYX Series fire alarm control panels, network control annunciators and legacy addressable panels. It communicates over an EIA-485 serial loop and can be located up to 6,000 ft from the panel. In the main control it is often used for manual selection of speaker and telephone circuits; for remote annunciation it mounts in ABS or ABF boxes.

FAQ
How many points can one ACM-24AT annunciate?
24 points on its own. Up to three AEM-24AT expander modules can be added for a maximum of 96 points. The AEM-48A cannot be used to expand the ACM-24AT.
How does it connect to the panel?
Over an EIA-485 multi-drop loop using four wires: a twisted pair for communication and two for 24 VDC regulated power. It can be up to 6,000 ft from the panel.
Which panels support it?
Notifier ONYX Series panels such as the NFS2-3030, NFS2-640 and NFS-320, network control annunciators, and legacy addressable panels. Up to 32 ACS annunciators can be connected, subject to the panel.
Which back box do I need for remote mounting?
Remote modules typically mount in ABS or ABF boxes, such as the ABS-1B surface box or ABF-1DB semi-flush box. Use the AKS-1B key switch where control switch security is needed, with a box deep enough to accept it.
