Section 5.4 Annunciator Modules
ACM-16AT*
The Annunciator Control
Module-16AT contains 16 red
alarm and 16 yellow trouble
LEDs, 16 momentary keypad
switches for controlling each
point, 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 at each
annunciator.
AEM-16AT*
The Annunciator Expander
Module 16AT expands the ACM-16AT
by 16 annunciator points. Up to three of
these expander modules can be supported by an
ACM-16AT, to a maximum of 64 annunciator points.
*Additional models exist that have different letter designations for different color LEDs: however, all functions
described are consistent for all models. For more details on the Annunciator Control System (ACS), refer to the ACS Manual.
The LDM-32
The LDM-32 Lamp Driver
Annunciator Module provides
32 alarm or 16 alarm and 16
trouble lamp driver outputs,
corresponding to 32
annunciator points which can
be connected to external
devices such as a custom
graphic annunciator. When
configured to provide 16
alarm and 16 trouble outputs,
16 switch inputs are available
for control of system
functions such as signal
silence, system reset, and
control module activation.
The LDM-E32
The Lamp Driver Annunciator Expander Module
LDM-E32 expands the LDM-32 by 32 annunciator
points (maximum of 64 points).
The LDM-R32
The LDM-R32 Relay Expander Module LDM-R32
provides the LDM-32 or LDM-E32 with 32 dry Form-A
(normally open) contacts. The relay module replaces the
lamp driver outputs with relay outputs; one LDM-R32 for
each LDM-32 or LDM-E32.
For more details on the LDM-32 Series Lamp Drivers,
refer to the LDM Manual.
SCS-8**
The Smoke Control Station
(SCS-8) module uses eight groups
of four annunciator points for fan
shutdown control or other heating,
ventilation or air conditioning
functions.
SCE-8
The Smoke Control Expander (SCE-
8) is used to expand the SCS-8 by an
additional eight groups of four
annunciator points. Only one
expander can be used per SCS-8.
SCS-8L**
The Smoke Control Lamp Driver Station (SCS-8L)
module uses eight groups of four annunciator points
for fan shutdown control or other heating, ventilation
or air conditioning functions. Must be mounted in
custom graphic annunciator panel.
SCE-8L
The Smoke Control Expander (SCE-8L) is used to
expand the SCS-8L by an additional eight groups of
four annunciator points. Only one expander can be
used per SCS-8L. Must be mounted in custom
graphic annunciator panel.
For more details on the SCS Smoke Control System,
refer to the SCS Manual.
** The SCS-8 and SCS-8L firmware has been updated in
conjunction with Software Release M2.8. The new SCS
