Problem
Cause
Solution
1.
False
high
sound
alarms
occur
frequently.
2.
High
sound
does
not
cause
an
alarm.
The
programmed
sound
sensitivity
results
in
over-sensitivity
to
non-alarm
sound
as
well
as
alarm sound. Sound
Recognition
Time
is
too
short.
The
unit
is
not
close
enough
to
the
high
sound
source, or the programmed sound setting results in a lack of sensitivity to high sound.
Reprogram
the
sound
sensitivity.
Refer
to
Chapter
5,
Section
5.10.
Lengthen
the
sound
Recognition
Time.
Refer
to
Chapter
5,
Section
5.10.
Move the unit closer or reprogram the sound sensitivity. Refer
to
Chapter
5,
Section
5.10.
Sound
Level Monitoring:
5.
False
high
temperature
alarms
from
freezer.
6.
The
Sensaphone
calls
with
a
high/
low temperature alarm but recites a temperature that’s within the programmed limits.
Most freezers have a defrost cycle during which the temperature will rise considerably, thus causing an alarm to occur. The
Sensaphone
recites
the
“current”
temperature when it calls you, not the temperature at the time the alarm occurred. It is likely that the temperature has changed since the time the alarm was detected and has since returned to normal operating conditions.
Program
an
zone
recognition
time
longer
than
the defrost cycle. Shorten the Call Delay or lengthen the Zone Recognition
Time.
