Application Example #3: Two LED-10 Annunciators and 10 Alarm Only Relays (no
system status)
Program the SFP-1024 at Level 3 addresses 02 - 03 for the proper address setting.
The address selected must be the highest or maximum address value selected on any
annunciator or ACM-8R connected to the EIA-485 port. (Refer to the Programming
Instructions Section 3 of the SFP-1024 Installation Manual P/N: 50475).
For this example, only one relay per SFP-1024 zone is required and the ACM-8Rs are
sharing the EIA-485 bus with two LED-10Ns. Since ACM-8Rs are sharing the bus with
two other devices, the address setting for the ACM-8Rs should be switches SW1 = 0
and SW2 = 3. Enter this address into the SFP-1024 Level 3 addresses 02 - 03.
Since each ACM-8R module contains eight relays, two ACM-8R modules are required
for 10 zones. Set the Mode Select switch SW4 for alarm only on both ACM-8Rs (SW4-
1 = ON). Set the first ACM-8R on the bus for Receive Only (SW4-2 = ON) and the last
ACM-8R for Receive/Transmit (SW4-2 = OFF). Set switch SW3 on the first ACM-8R so
that SW3-2 = ON and SW3-5 = ON, and the remaining switches are OFF. Set SW3 on
the last ACM-8R so that SW3-3 = ON and SW3-5 = ON, and the remaining switches
are OFF.
Note: Figure A-2 is provided as an application example and is not intended to be used
as a wiring diagram. Refer to Figure A-1 or the appropriate manuals for detailed wiring
information.
