Hardware Configuration
The LCI-90 will work with a wide variety of input sensors, output alarms and data systems. The
4.0 SYSTEM CONFIGURATION
menu, shown below, allows the LCI-90 to be customized for
a particular installation. Once these settings have been made, this menu also offers a security fea-
ture that locks out unauthorized changes. Should it happen, however, that unwanted changes to
the configuration are made, it is possible to return to the "Factory Setup" configuration, which can
be customized for a given installation. The functions of each item in this menu are described in
Sections 6.1-6.6.

6.1
Security
Security is either
OFF (0)
or
ON (1)
. When Security is
ON
most of the RUN functions are
disabled, i.e.
RSET
,
CALB
and
ALRM SET
are locked out. The user can access the
DIAG screen(s), and can silence alarms, but all menu items are locked out except for the
security option.
To change the Security setting, press
ENT
. This will highlight the default value (0=off, 1=
on), and allow the operator to enter a security code. This number can be any value between
2 and 255, which will become the security unlock code, so it should be kept in a safe place.
Once a number is entered (and
RUN
is pressed to save the change), the security lockout
feature is enabled, and can only be disabled by re-entering the
same number
.
6.2
Factory Setup
This item always defaults to
NO
; pressing
ENT
and changing the value to
YES
, followed
by a second
ENT
will immediately restore all configuration parameters to their "Factory
Setup" values. This operation should only be necessary in cases where the LCI-90 does not
seem to be working properly and it is desired to return to a known configuration in order to
perform long-distance troubleshooting. All existing configuration parameters are lost and
the display will return to RUN mode automatically after this operation.
