Since most Informant installations are
wall-mounted to refrigeration rooms,
an external antenna is required.
Depending on the type of building, the
antenna can be mounted above the
conduit.
In all-metal buildings, a roof-mounted
antenna will be required.
When the Informant will be more than
five miles from the cell phone tower
a directional antenna will likely be
required.

setting those. However, the delay time before sending an alarm is set on this page.
Many delays are used on switch and contact functions.
Temperature: delay alarm to ignore defrost cycle. Typically 30-45 minutes.
Door Position: delay alarm to allow door to be open for a period. Typically 5 minutes.
Refrigeration Leak: delay to assure that genuine leak is present. Typically 15 minutes.
Set delays carefully. A short delay causes false alarms, a long delay may mask prob-
lems.

There are two internal batteries that keep the Freezer Alert running when city power is
lost. The batteries last for 24 hours or more. When they are exhausted, they must be
replaced with CR123A cells which are available at Walmart.
Testing the City Power Alarm.
Unplug the wall transformer from the power receptacle. The display should go
dim as the unit starts to conserve battery power. After two minutes, you should
receive a text message alarm.

Loss of city power is a critical failure. The
Informant contains two Lithium batteries
that automatically keep the Informant run-
ning when city power fails.
When power fails, text message alarms are
sent and the event is logged.
There is a one!minute delay before
alarming to ignore transient power spikes of
black outs.
