B.1 Capabilities
ACS annunciation displays the 99 software zones of the AFP-200, plus 8 system points, for a total point count of 107. Information is trans-
mitted using only addresses 1 and 2. Up to 32 devices can be driven by the EIA-485 communications output, using two unique addresses
with 64 points at an address. Two-way communications can occur with only one annunciator per address; other devices on the same address
must be configured as "Receive Only". The furthest annunciator can be separated from the control panel by no more than 6,000 feet of wire
(@16AWG); check specific current requirements for your system.
CAUTION: NOT FOR MANUAL CONTROL
!
ACS ANNUNCIATORS ON THE AFP-200 CANNOT BE USED FOR MANUAL CONTROL OF CONTROL MODULES, BELL
CIRCUITS, OR RELAYS (EXCEPT FOR GLOBAL SILENCE AND DRILL SWITCHES).
B.2 Connecting the EIA-485 Circuit
EIA-485 wiring is connected to TB5 of the AFP-200 as shown in the accompanying illustration.
•
Set SW2 on AFP-200 to "ACS" position.
•
EIA-485 circuit rated 5.5 VDC max., 60 mA max.
See Section 4.3 for details and notes about EIA-485 requirements.
B.3 Providing Power to Annunciators
The annunciator's power supply is connected to +24V non-resettable power; use the middle two pins on TB1 of
the AFP-200 as shown in the accompanying illustration. See Section 4.6 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.
