3.14 Alarm Time Delay
Each individual alarm can be programmed with a time delay (
Table 16
), causing the unit to delay
a specified amount of time (0-255 seconds) before recognizing the alarm. The alarm condition
must be present for the full amount of the time delay before the alarm will sound. If the alarm
condition is diverted prematurely, the alarm will not be recognized and the time delay will auto-
matically reset.
3.15 Common Alarm Enable
Each individual alarm can be selected to activate/deactivate the common alarm relay. If the ener-
gize common alarm function is set to
YES
, the relay is energized immediately as the alarm is
enunciated, and de-energized when the alarm condition has cleared. If the alarm is completely
DISABLED, the alarm has no effect on the common alarm relay. Use the
UP/DOWN
arrows to
scroll to a particular alarm, press the
ENTER
button to select it, then press the
ENTER
key
again to select Yes or No.
3.16 Custom Alarms
The custom alarm messages can be selected from a list of standard alarm messages, or the opera-
tor can write his/her own message. A MAXIMUM OF THREE (3) ALARM MESSAGES CAN BE
CUSTOMIZED.
The text for custom alarms can be changed at any time by selecting “CUSTOM ALARMS”. To
change the text for a custom alarm, select the alarm you would like to change, 1, 2 or 3. Using the
UP/DOWN
arrows, step through the list of seven standard alarm messages (listed below) and two
custom alarms. Select the alarm message desired and store it by pressing
ENTER
.
•SMOKE DETECTED
•CUSTOM 2
•CUSTOM 3
•STANDBY GC PUMP
• WATER FLOW LOSS
•STANDBY UNIT ON
•CUSTOM 1
NOTE
For software alarms such as “loss of power” and “short cycle,” the time
delay should be left at the factory default of 0.
