Alarm switch enabled and alarm switch valid level are required to be noted when checking
the Boolean alarm both on the SMT and the LMT. The following part takes the Door Open
Alarm of the DEMU as an example to describe the procedure for testing the Boolean alarm.
NOTE
Trigger conditions of the Door Open Alarm: When the cabinet door of the BTS is open, the
l
DEMU reports Door Open Alarm; when the cabinet door of the BTS is closed, the Door Open
Alarm is cleared.
Disable the Door Open Alarm and configure the alarm valid level: When the Door Open
l
Alarm is disabled, the DEMU does not report the Door Open Alarm. In other words, the Door
Open Alarm is shielded. Alarm valid level configuration specifies the valid level of the door
sensor alarm, which is determined by the attribute of the field Gate Magnetism.
On the LMT, choose Alarm Maintenance > Browse Alarm. Check the alarm information in
l
the displayed Browse Alarm dialog box.
1. Check whether the Door Open Alarm can be reported normally by opening the
cabinet door of the BTS and be cleared normally by closing the cabinet door of the
BTS.
If the alarm can be reported and cleared normally, end the checking task.
–
If the alarm cannot be reported, go to
–
Gate Magnetism.
TIP
If the valid level of the door sensor alarm on site is inconsistent with the valid level of the door
sensor alarm based on the data configuration, the reported alarms are opposite. For example,
if the valid level of the door sensor alarm on site is high and the configured valid level is low,
then:
When the cabinet door of the BTS is closed, the DEMU reports the Door Open Alarm; when
the cabinet door of the BTS is open, the Door Open Alarm is cleared.
2. In the BSC6000 Local Maintenance Terminal window, right-click the site to be
queried and choose Configure Site Board Attributes. The Configure Site Board
Attributes dialog box is displayed.
3. Click Configure Site Board Attributes, the Site Device Attributes dialog box is
displayed.
4. Right-click DEMU, choose Configure Site Board Attributes. The Basic Attributes
of Site Board dialog box is displayed.
5. Click the Configure Site Board Attributes tab. Then set Board Parameter
Configuration Enabled to Yes. Click Special Alarm Switch Enabled to check
whether Gate Magnetism(Disabled) is selected, as shown in
In normal conditions, the check box Gate Magnetism(Disabled) is deselected,
–
which means it is enabled and the Door Open Alarm is reported once the alarm is
generated.
If the check box Gate Magnetism(Disabled) is selected, deselect the check box.
