"old" alarms in memory.
2. Unacknowledged alarms Date/Time &'Al-ARMS"displayed.

alarms. Press "RESET' ONCE TO
SILENCE, TWICE TO COMPLETELY
RESET ALAHM. lf alarm reoccurs, the
annunciator will sound again.
When the unit is first powered ON, the display will indicate the time, date, and "NO
A1-ARMS". lf the unit'has been powered rip Sireviously, the internal memory may contain
alarm messages. lf this is the c'ase, the stored. alarms may be reviewed by press.ing .
either of the irrow buttons. lf no alarms have been stored, the display will show blank
alarms when scrolling with the arrow buttons.
- 2. Displaying Alarms
The following will describe the use of the arrow buttons to scrollthrough alarms stored
in memory.
The alarm messages may be thought of as a list on a sheet of paper. The display is
simply a window moving'up or down the page viewing the first two or second two lines
of any one alarm. Eaclialarm is made up olfour lines (two screens).
The down arrow will take you to the second two lines of an alarm, or to the next alarm,
depending on where you -are at when you press it. The first two lines of an alarm give
informatioh about timir and date and unit number, the second two lines give a
description of the alarm.
The up arrow willtake you to previous alarms or from the second two lines of a given
alarm to the first two lines of that alarm.
Pressing both arrow keys simultaneously will set the display back to viewing .'A[-ARMS"
or "NO ALARMS" and ttie scrolling wind6w back to Alarm #1. The unit will store a
maximum of 20 alarms.
3. Receiving Alarms
When the unit receives an alarm message, the LCD will display the wgrd "A[ARMS', the
alarm L.E.D. will illuminate, and the audi-ble alarm will sound (if the unit is set to do this).
At this point, the RESET button can be pressed once to silence the audible alarm. This
will allow thd user to view the current alarm(s) without the annoyance of the audible
alarm. lf the RESET button is pressed a sebond time, the current alarms in the 485
Alarm will be acknowledged ahd a "Fleset Alarms" message will be broadcast to all
attached devices that reSpond to the 485 Alarm. Before resetting alarms,.the pending
problems should be solvdld or the alarm will reoccur and equipment problems or
product loss could occur.
lf the 485 Alarm loses communications, it willturn on both the LED and audible alarms
ind display "Network Down". This may be.acknowledged Py pre^ssing the RESET
Outton.'This error suggests a wiring oi switch setting problem. Communications will be
initiated by another d6Vice in tess than 5 minutes or i-mmediately upon powering up the
485 alarm.
