2.8.1 Annunciators with 24- and 48-Point Capacity
For specific installation information, refer to the Annunciator Control Module manual. For
Canadian requirements, see Appendix D “Canadian Applications”.
Annunciator Control Module - ACM-24AT A one-channel Class-B unit with 24 switch
controlled annunciator points. Each point is controlled by a silicone-rubber switch with indicator
LED. Multi-color LEDs can be programmed to produce one of three colors: red, green or yellow.
Annunciator Expander Module - AEM-24AT An expander board for the ACM-24AT that
provides an additional 24 points and is identical in size and appearance. Up to three expanders can
be used with an ACM-24AT.
Annunciator Control Module - ACM-48A A one-channel Class- B unit with 48 annunciator
points for indicating current system status. Each annunciator point has a red LED for alarm, and a
green LED for normal; each module has a yellow unit-trouble LED at the top.
Annunciator Expander Module - AEM-48A An expander board for the ACM-48A that
provides an additional 48 points and is identical in size and appearance. One expander can be used
with an ACM-48A.
2.8.2 Annunciator Fixed Modules
Introduction
Provide the control panel with discrete display and control points. Fixed modules turn their LEDs
on and off as directed by the control panel, and also report switch activations to the control panel
for action. You can only use one fixed module in a system. Each annunciator’s address is fixed at
address 1.
Refer to the Annunciator Fixed Module manual for further information.
Description
Annunciator Fixed Module - AFM-16AT Contains 16 red alarm and 16 yellow trouble LEDs,
a system trouble LED, an Online/Power LED, and a local sounder, and switches for control panel
Acknowledge, Alarm Silence, and System Reset. Use the AFM-16AT for systems that require 16 or
fewer annunciation points.
Annunciator Fixed Module - 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
AFM-32A is fixed at address 1, and will not accept expander modules.
