Troubleshooting
II. TEMPERATURE
MONITORING
1. The temperature reading
is low: -85°F or -65°C.
2. The temperature reading
is high: 200°F or 93°C.
3. The temperature reading
is inaccurate.
III. SOUND MONITORING
1. False high sound alarms
occur frequently.
2. High sound does not
cause an alarm.
IV. OTHER
1. Alarm status of input is
incorrect.
2. The unit won't perform an
autotest.
3. The unit calls again with
the same alarm after I
acknowledge it.
Troubleshooting
Check wires for a loose connection or
broken wire.
Check the wiring to see if the wires touch.
Replace the sensor with a compatible
model.
Calibrate the input. See “Inputs” in
Chapter Five for information on calibrating
the input properly.
Reprogram the sound sensitivity to a
less sensitive value and increase the
recognition time. See “Sound” in Chapter
Five.
Move the microphone closer to the sound
source and/or reprogram the sensitivity
and recognition time. See “Sound” in
Chapter Five.
Reprogram the input type to the correct
normality. See “Inputs” in Chapter Five.
Disable the Call Cancel feature. (See
Chapter Five)
Increase the “Alarm reset” value. See
“Alarm Reset Time” sections in Chapter
Five and “Alarm is Acknowledged” in
Chapter Six.
Lengthen recognition time. See various
“Recognition Time” sections in Chapter
Five.
Open circuit on the input.
The circuit is shorted.
The sensor may be
incompatible with the unit.
See 2.8K and 10K thermistor
look-up tables in Chapter
Three.
The sensor may simply need
calibration.
The programmed sound
sensitivity and recognition
time results in over-sensitivity
to non-alarm sounds as well
as alarm sound.
The microphone is not close
enough to the sound source,
or the programmed sound
setting results in a lack of
sensitivity to the high sound.
Incorrect input normality.
The call-cancel feature is
enabled. An auto test won't
execute if this feature is
enabled.
Alarm reset time is set at too
short an interval.
Alarm condition is sporadic,
going on and off.
