6 ProductConguration
6.1 Install Battery for Backup Power
The monitoring system and chart recorder each have a battery system, enabling a period of continuous
operation if power is lost.
NOTE ► The optional Access Control system uses the monitoring system battery for backup
power, in the event of a power failure.
► The monitoring system will start on battery power alone. If the refrigerator was
previously not connected to AC power and the battery is switched on, the monitoring
system will begin running on battery power.
Battery life varies by manufacturer as well as voltage level remaining. Providing full power is available
and no battery-related alarms are active, backup power for the monitoring system is available for up to
20 hours (the Low Battery alarm will activate after approximately 18 hours of battery use). Providing full
power is available, backup power for the optional Access Control system is available for up to 2.5 hours.
!
CAUTION ► Before installing or replacing batteries, switch the power and battery OFF.
Disconnect the refrigerator from AC power.
NOTE If AC power is lost, the monitoring system will automatically disable some features to
prolong battery power. Data collection will continue until battery power is depleted.

6.2 External Monitoring Devices
The remote alarm interface is a relay switch with three terminals:
► Common (COM)
► Normally Open (NO)
► Normally Closed (NC)
Terminals are dry contacts and do not supply voltage. Interface circuit is either normally open or normally
closed, depending on terminals used.
Requirements for your alarm system determine which alarm wires must connect to terminals.
!
CAUTION ► The interface on the remote alarm monitoring system is intended for connection to
the end user’s central alarm system(s) that uses normally-open or normally-closed
dry contacts.
► If an external power supply exceeding 33 V (RMS) or 70 V (DC) is connected to the
remote alarm monitoring system’s circuit, the remote alarm will not function properly;
may be damaged; or may result in injury to the user.
The terminals on the remote alarm interface have the following maximum load capacity:
► 0.5 A at 125 V (AC): 1 A at 250 V (DC)
