Display Display group Description
En Enclosure Number The enclosure number is the default display and is a decimal
number in the range 00 through 14. See Using the Enclosure

the enclosure bay 1 loop ID. Valid loop IDs are in the range
00 through 7F.

audible alarm disabled (oF). See Audible Alarm Operations
for detailed information.
Fr Firmware Revision This display group defines the EMU code firmware version.
Er Error Condition This display group reads Er when there is an error condition.
NOTE:
Any time you press and release the bottom push button the display will change to En, Li, rG, Au, or Er.
A flashing alphanumeric display indicates that you can edit an address, state, or view a condition report.
EMU push button status indicators
The push button status indicators display error conditions and the state of the audible alarm .
• When an error condition exists, the top push button status indicator is On.
• For a single error condition, the status indicator is On until the error condition is viewed.
• For multiple errors, the status indicator is On until the last error condition is viewed.
• The bottom push button indicator is On only when the alarm is muted or disabled.
Audible alarm operations
Whenever an error condition exists, the audible alarm automatically sounds until all errors are corrected.
You have the option of either muting or disabling the alarm.
• Disabling the audible alarm prevents it from sounding for any error condition.
• Muting the alarm silences it for the existing condition, but any new condition causes the alarm
to sound.
Audible alarm patterns
The audible alarm sound pattern differs depending on the type of error condition. See Table 17 for the
duration and the approximate relationship of these alarms. The most severe, active error condition
controls the alarm pattern.
