System does not Alarm
If the alarm light is not flashing and there is no alarm sound when detecting the label, first whether the
frequency of the label is the same as the frequency of the emission center, check whether the warning
light, the buzzer wiring is good, and whether the warning light or the buzzer itself is damaged. If there is
no, check the indicator ALARM on the printed circuit board. “Bright” indicates that the system has alarmed,
but there is no alarm output. At this time, some circuit faults (component failure or damage) should be
considered.
Note:
When the environmental interference is very serious (the noise level indicator lights up), the system
will not work properly.
System Error Alarm
For a radio-frequency system, accidental false alarms due to interference from broadband interference
sources such as certain radio waves or electrical switch sparks are allowed and do not fall within the
system's fault range. However, frequent false alarms or even continuous self-sounding should be a serious
failure. At this time, in addition to finding a strong source of interference and eliminating it, the system
itself should also be inspected and trouble-shooted. It is also possible to solve the problem of false alarms
by setting debugging methods such as modulation frequency, signal synchronization, adjusting sensitivity,
and adjusting scan frequency offset.
