A.1 Capabilities
The AFP-100 allows annunciators to be programmed by zone or by point. The EIA-485 interface will allow up to 32 annunciators with 64
points at an address, but two-way communications can occur with only one annunciator per address. The other devices must be configured as
"Receive Only".
When the panel is programmed by zone, annunciator address 1 is available, and ACS annunciation displays the 56 software zones of the
AFP-100. When the panel is programmed by point, 198 points are available. Annunciator addresses 1, 2, 3, and 4 can be used, but only
address 1 is supervised.
The furthest annunciator can be 6,000 feet from the fire alarm control panel (check power limitations).
CAUTION: NOT FOR MANUAL CONTROL
!
ACS ANNUNCIATORS ON THE AFP-100 CANNOT BE USED FOR MANUAL CONTROL OF CONTROL MODULES, BELL
CIRCUITS, OR RELAYS (EXCEPT FOR GLOBAL SILENCE AND DRILL SWITCHES).
A.2 Connecting the EIA-485 Circuit
EIA-485 wiring is connected to TB5 of the AFP-100 as shown in the accompanying illustration.
See Section 4.3, "EIA-485 Wiring Specifications" for details and notes about EIA-485 requirements.
A.3 Providing Power to Annunciators
The annunciator's power supply is connected to +24V non-resettable power; use the middle two pins on TB4 of
the AFP-100 as shown in the accompanying illustration. See Section 4.6, "Annunciator Power Requirements &
Electrical Ratings" for specifications.
The power run to the annunciator need not contain a Power Supervision Relay because loss of power is inher-
ently supervised through communication loss. This 24 VDC output is power-limited, filtered, and non-resettable.
A.4 Configuring Annunciators for AFP-100
The switch numbers given below are for SW28 on the ACM-24AT and ACM-48A, and for the 8-pin DIP switch on the ACM-16AT and
ACM-32A. Address and DIP switches must be set before the annunciator will operate properly. See Section 5.2, "Connections and
Switches" for switch locations.
Switch #
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 5.12.3, "Configuring
Number of Expander Modules" for ACM-24AT/ACM-48A; see Section 5.13.3, "Configuring Number of Expander Modules" for ACM-
16AT/ACM-32A.
4
Not used; set to OFF
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 AFP-100. 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.

For ACM-24AT and ACM-48A with AFP-100, set all pins on SW32 to "OFF".

ACM-16AT and ACM-32A Function
Eight-Point Shift: Set switch "ON" to shift the control panel functions
from the first eight annunciator positions to expander positions 57-64.
This shift can only be set on an annunciator set for address "1".
