BATTERY BACKUP & POWER FAILURE ALARM
The D-100 battery backup system uses 4 each AA rechargeable batteries. During the
power failure, the batteries will support the alarm system and the temperature display
for 8 hours. When the power resumes, the batteries will be automatically recharged.
During a power failure event, the visual display will turn into flashing red background
with “PF” (power failure) message. Audible alarm & remote alarm contact would be
activated to alert users. The D-100 will still display and monitor the refrigerator
temperature during a power failure event until the battery power is depleted.
Once the power resumes, the display will still be flashing red, and showing “PF”
message, even if the refrigerator’s temperature is normal. It is a feature to alert
users that a power failure event has occurred. Users should check the temperature
history on the display. To clear the “PF” message, press any button.
