Providing Power to Annunciators
System 5000 Systems: ACM-16AT and ACM-32A Only (UL 8th)
G.3 Providing Power to Annunciators
MPS-24A Main Power Supply
Connect the power run for the ACS to +24V non-resettable power on TB3 of MPS-24A, as shown in
accompanying illustration (filtered, power-limited, 3 amps max).
MPS-24B Main Power Supply
Cut JP1 on MPS-24B to make the circuit non-resettable and connect the power run for the ACS to
MPS-24B TB2 Terminals 1 (+) and 2 (-) as shown in the accompanying illustration (filtered, power-lim-
ited, 200 milliamps max).
G.4 Installing Modules in the System
The ACS begins annunciation with the control panel and continues with the annunciation of circuits on the module installed directly after the
control panel. To ensure full employment of ACS points, mount System modules that require annunciation in the control panel row first, then
in the second row, etc. Modules with circuits that need not be annunciated by the ACS should be installed further down in the cabinet.
Top Row: Annunciator Address “1”
Points 1-32, annunciated by either the first ACM-16AT and its first expander, or by the first ACM-32A.
2nd Row: Annunciator Address “1”
Points 33-64, annunciated by either the second and third expanders of an ACM-16AT, or by an AEM-32A
expander.
3rd Row: Annunciator Address “2”
Points 65-96, annunciated by either the second ACM-16AT and its first expander, or by the second ACM-32A.
4th Row: Annunciator Address “2”
Points 97-128, annunciated by either the second and third expanders of the second ACM-16AT, or by an AEM-
32A.
NOTE:
Cut JP1 on MPS-24B to make this circuit non-resettable. Do not use this connection to
simultaneously power four-wire detectors and annunciators. See the
System 5000 Manual
for
location of JP1.

NOTE:
Without invoking the Eight-Point-Shift, the first eight points would be dedicated to control panel
functions, not circuits of the first module. (See Section G.5, “Configuring the ACS for System 5000”.)
