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:
Problem Cause Solution
1. Alarm status of an alert input is
incorrect.
2. False power out alarms
Incorrect input normality.
Programmed Recognition Time is too short.
Reconfigure the input.
Refer to Chapter 5, Section 5.1.
AC power is often subject to brief
interruptions. To avoid frequent, false alarms,
increase the power Recognition Time.
Refer to Chapter 5, Section 5.9.
