Annunciator Fixed Modules (ADT-AFM-16AT and ADT-AFM-32A) provide the
control panel with discrete display and control points. ADT-AFMs turn their LEDs on
and off as directed by the CPU, and also report switch activations to the CPU for action.
You can only use one ADT-AFM in a system. Each annunciator’s address is fixed at
address 1.
• ADT-AFM-16AT – The ADT-AFM-16AT contains 16 red alarm and 16 yellow
trouble LEDs, a system trouble LED, an On-line/Power LED, and a local sounder,
and switches for control panel Acknowledge, Alarm Silence, and System Reset.
Use the ADT-AFM-16AT for systems that require 16 or fewer annunciation points.
• ADT-AFM-32A – The ADT-AFM-32A contains 32 red alarm LEDs, a system
trouble LED, an ON LINE/POWER LED, and a local panel sounder with a silence/
acknowledge switch. The ADT-AFM-32A is fixed at address 1, and will not accept
expander modules.
