Enable Alarms: Each individual alarm can be selected to be ENABLED (annunciated audibly, visu- ally, and communicated to a Site Products System) or DISABLED (ignored).

Enable Common Alarm: Each individual alarm can be selected to energize or to not energize the common alarm relay. If the energize common alarm function is set to YES, the relay is energized immediately as the alarm is annunciated and de-energized when the alarm condition goes away (only after the alarm has been recognized). If the function is set to NO, the alarm has no effect on the com- mon alarm relay regardless of whether the alarm is ENABLED or DISABLED.

Set Custom Alarms: The custom alarm messages can be from a list of standard alarm messages or you can create your own message.

NOTE

Only one (1) or two (2) of the alarm messages can be your own message.

They can be in any location(s) 1 through 4. The text for custom alarms can be changed at any time by selecting “SET CUSTOM ALARMS”. To change the text for a custom alarm, select “SELECT ALARM”. Then, select which alarm you would like to change, 1 through 4. Using the UP/DOWN arrows will step through the list of five standard alarm messages (see Standard Alarm Messages on page 12) and the two custom alarms.

NOTE

The two custom alarm message will be shown with what was previously programmed in them and can be changed.

Press ENTER to make your selection. To modify the two custom alarm messages, go back one screen and select “CHANGE CUSTOM TXT 1” (or 2). Text can be up to 20 characters in length and can be any of the following characters (or a blank space):

ABCDEFGHIJKLMNOPQRSTUVWXYZ#%*-0123456789.
