1.3 SW1 DIP Switch Settings
Refer to “DIP Switch Settings Example” on page 12, for an explanation
of DIP switch positions. SW1 switch settings follow:
1 - On = Key-switch disabled, Off = Key-switch enabled.
Switch 1 set to the Off position enables key-switch operation. The
key-switch may now be used to enable the FDU-80 membrane
switches, allowing remote switch functions, or lockout the switches,
preventing remote switch functions
Switch 1 set to the On position disables the key-switch operation.
Refer to “Switch Functions” on page 15, for key-switch function
description.
2 - On = Piezo sounder enabled, Off = Piezo sounder
disabled.
CAUTION: Piezo sounder must not be disabled without prior
approval of the Local Authority Having Jurisdiction (LAHJ).
3 - On = Receive/Transmit, Off = Receive Only.
Set switch 3 to Off position for all FDU-80 Annunciators except the
last (or only) annunciator on the EIA-485 loop. Set switch 3 to On
position for the last or only annunciator on the EIA-485 loop to
allow transmission of a supervision signal and function switch
depressions back to the FACP.
The last or only annunciator must be
set for Receive/Transmit (switch 3 in the On position).
A break (open circuit) in the power or EIA-485 connections creates
an FDU-80 Annunciator fault at the control panel. All annunciators
before the break will continue to display information (
but the func-
tion switches on the FDU-80 will no longer operate )
