SW1 DIP Switch Settings
The OPEN position on SW1 is the OFF state. Refer to Figure 1-3 for an explanation of
DIP switch positions. SW1 switch settings are as follows:
1 through 6 - LED-10 Series annunciator address switches.
The first six switches are used to set the address of the annunciator. The OFF
(OPEN) up position equals a binary 1 and the ON down position equals a
binary 0. Refer to Table 1-1 for information on setting these switches for
specific addresses. Each LED-10 Series annunciator connected to the EIA-
485 communication bus must have a unique address.
7 - Not used
8 - ON = Receive/Transmit, OFF (OPEN) = Receive Only
Switch 8 set to ON position enables Receive/Transmit mode for the LED-10
Series annunciator. This allows the annunciator to receive and display system
status information and to transmit supervision status. It also allows the LED-10
model to transmit system control data such as Acknowledge/Step, Reset,
Signal Silence and Drill. Switch 8 set to the OFF position enables Receive
Only mode which allows the annunciator to receive and display system status
information but prevents supervision status from being transmitted back to the
FACP. It also prevents function switch operation on the LED-10 model. To
ensure annunciator supervision for all LED-10 Series annunciators and
function switch capability for the LED-10 model, each annunciator connected to
the EIA-485 communication bus must have a unique address and should be
set to enable Receive/Transmit Mode.
