1.3 SW1 DIP Switch Settings
Refer to “DIP Switch Settings Example” on page 13, 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 LCD-80F 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 16, 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 = Supervision Receive/Transmit, OFF = Supervision Receive
Only.
• One Annunciator - if a single LCD-80F is the only annunciator
connected to the EIA-485 loop, Switch 3 must be set to the ON
position to allow the FACP to supervise the annunciator.
• Multiple Annunciators - if multiple LCD-80F annunciators are
connected to the EIA-485 loop, the annunciator physically
connected as the last device on the loop (farthest from the ‘OUT’
terminals on the FACP) must have Switch 3 set to the ON
position in order to supervise all annunciators on the loop. All
remaining annunciators must have Switch 3 set to the OFF
position for proper supervision and operation.
It is important to note that the function switches on all LCD-80F
annunciators will operate regardless of the setting of Switch 3.
A break (open circuit) in the power or EIA-485 connections creates
an LCD-80F Annunciator fault at the control panel. All annunciators
before the break will continue to display information (but the
function switches on these LCD-80Fs will no longer operate).
