Signal Information Modification Sub-Menu

Here you can change the name of signals connected to the Controller. Signals have two names. One is
the “Signal Full Name” and another is the “Signal Abbreviated Name”. The “Signal Full Name” is displayed
in the WEB Interface menus and the “Signal Abbreviated Name” is displayed in the local LCD display
menus.

Enter the new signal name in the “New Name” column and select what Name is to be changed (“Signal
Full

Name” or “Signal Abbreviated Name”). Click on the "Set" button to save the new name.

Signal Full Name (32 characters maximum).

Signal Abbreviated Name (15 characters maximum).

Note: If a signal is renamed it is recommended to retain enough information about the physical location

of the signal as possible. As an example, if you want to assign a name of 'Intrusion 6' to the signal
who's default name is 'DI1 Alarm' it could be labeled 'DI1 Intrusion 6'. This will help in physically
locating the wiring etc. related to the 'Intrusion 6' alarm. Alternately, the customer could label the
wiring and/or position that is related to the signal name.
