Product Overview
3.3.2 Expander Modules
1
AEM-16AT
The Annunciator Expander Module-16AT expands the ACM-16AT series by 16 system points. The AEM-16AT series is identi-
cal in size and in frontal appearance to the ACM-16AT series. One to three of these expander modules can be supported by an ACM-16AT,
ACM-16ATG, or ACM-ATY, to a maximum of 64 system points. Height = 8.375" (21.27 cm), Width = 4.375" (11.11 cm).
NOTE: The AEM-16AT series cannot be used to expand the ACM-24AT, ACM-48A, or ACM-32A series. Expander LED colors need not match
the control module LED colors for the expander to operate.

AEM-16ATY
Same as the AEM-16AT but all LEDs are yellow (yellow On/Alarm and yellow Trouble).
1
Same as the AEM-16AT, but On/Alarm LEDs are green (green On/Alarm and yellow Trouble).

3.4 ACM-32A Series
3.4.1 Control Modules
1
The Annunciator Control Module-32A contains 32 red point active LEDs, a system trouble LED,
ACM-32A
an On-line/Power LED, and a local piezo sounder with a silence/acknowledge switch for audible indication of
alarm and trouble conditions at each annunciator. Height = 8.375" (21.27 cm), Width = 4.375" (11.11 cm). In
Canada this module must be used to annunciate the fire alarm input points/zones only.
1
Same as the ACM-32A, but On/Alarm LEDs are green (green On/Alarm and yellow Trouble). In
ACM-32AG
Canada this module may be used to annunciate notification appliance circuit activation or other output cir-
cuit/zone activation.
1
Same as the ACM-32A but with all LEDs yellow (yellow On/Alarm and yellow Trouble). In Can-
ACM-32AY
ada this module must be used to annunciate supervisory and burglary signals from associated points/zones.
3.4.2 Expander Modules
1
The Annunciator Expander Module-32A expands the ACM-32A series by 32 system points. The AEM-32A (with red LEDs) is
AEM-32A
identical in frontal appearance to the ACM-32A. One expander module can be supported by an ACM-32A, ACM-32AG, or ACM-32AY,
providing a maximum of 64 points. Height = 8.375" (21.27 cm), Width = 4.375" (11.11 cm).
NOTE: The AEM-32A cannot be used to expand the ACM-24AT, ACM-48A, or ACM-32A series. Expander LED colors need not match the
control module LED colors for the expander to operate.

AEM-32Y
Same as the AEM-32A but with all LEDs yellow (yellow On/Alarm and yellow Trouble).

3.5 Cabinet & Panel Hardware
NOTE: For Canadian Applications, only the ABF-1BC, ABS-1BC, ABS-2DC, ABS-1TBC backboxes and the ADP-4B, DP-DISP, DP-DISP2,
and ADP2-640 mounted in the CAB-4 Series Cabinets are approved for annunciator installation.
3.5.1 Surface-Mount Backboxes
These backboxes provide a surface-mount enclosure for remote mounting annunciators. Knockouts are provided for use
with 1/2" conduit. Dimensions are provided in Table 3.1.
ABS-1B
Mounts one annunciator directly to the ABS-1B without a dress plate. This backbox will not support the installa-
tion of the Annunciator Keyswitch or the Annunciator Phone Jack for Firefighters' Telephone.
Mounts two annunciators directly to the ABS-2B without a dress plate. This backbox will not support the instal-
ABS-2B
lation of the Annunciator Keyswitch or the Annunciator Phone Jack.
ABS-2D, ABS-2DR
support the installation of the Annunciator Keyswitch or the Annunciator Phone Jack for Firefighters' Telephone.
ABS-4D, ABS-4DR
mounted semi-flush. This backbox will not support the installation of the Annunciator Keyswitch or the Annunciator
Phone Jack for Firefighters' Telephone.
Mounts one annunciator. Unlike the ABS-1B and ABS-2B, the ABS-1TB has an increased depth that allows mounting of the
ABS-1TB
Annunciator Phone Jack for Firefighters' Telephone and Annunciator Keyswitch.
1. In Canada the color red must be used to indicate active alarm inputs. Yellow indicates supervisory, burglary or trouble signals.
Green indicates the presence of power, or an activated output.
