Note: Address and DIP switches must be set before the annunciator will operate
properly.

Switch
# ACM-16AT and ACM-32A Function
1 Not used: This switch must be set “OFF”
2, 3 Expanders installed: Set these switches according to how many expanders are
installed at the address. See Section 4.13.3 “Configuring Number of Expander
Modules”
4 Eight-Point Shift: Set switch “ON” to switch the control panel functions out of the first
eight annunciator points. This switch is intended for systems between 9 and 16 circuits
and employing one ACM-16AT (with no expander) where annunciation of all circuits is
desired.
5 Receive Only: Set this switch “ON” for each annunciator that will provide the same
information as another annunciator in a different location. (When two or more
annunciators hold the same address, all but one must be configured as “Receive Only”
annunciators.)
6 Piezo Disable: Set this switch “ON” to disable the piezo from sounding for any event.
(The piezo will also be disabled if Flash Inhibit is “ON”.)
7 Switch Inhibit: Set this switch “ON” to disable the point control switches on the
annunciator and prevent them from executing system control functions. When
inhibited, the switches will serve as local Lamp Test switches only. In addition, the
Acknowledge/Lamp Test switch will function only in a local capacity unrecognized by
the system.
NOTE: Only the first four switches control the System 500. Their functions are:
1=Acknowledge 2=Signal Silence, 3=System Reset, 4=Drill.
8 Flash Inhibit: Set this switch “ON” to disable the flashing of LEDs associated with
unacknowledged events. Flash Inhibit also disables the piezo from sounding.
