Procedure

4-28 l Commissioning the Boolean alarm (Door Open Alarm of the DEMU)



Issue 02 (2009-04-20)

BTS3900(A) GSM


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 l l

Trigger conditions of the Door Open Alarm : When the cabinet door of the BTS is open, the

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

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.

l On the LMT, choose Alarm Maintenance > Browse Alarm . Check the alarm information in 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 Step 2 to check the data configuration of the

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 Figure 4-26 .

–

–

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.

6.

Click Special Alarm Switch Valid Level Configuration in the Basic Attributes of

Site Board dialog box. Check whether the configuration of the Gate Magnetism(Low

Level) is consistent with the actual alarm switch valid level of the Gate Magnetism,

as shown in Figure 4-27 . If the alarm switch valid level of the field Gate Magnetism

is high level, then

–

In normal conditions, the check box Gate Magnetism(Low Level) is deselected, which means the Door Open Alarm is reported at a high level.

–

If the check box Gate Magnetism(Low Level) is selected, deselect the check box.

7.

When the checking is complete, 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, reconnect the related monitoring signal cable. For details, see the BTS3900 Quick Installation Guide or the BTS3900A Quick

Installation Guide .

l Commissioning the alarm reported through the RS485 port (temperature monitoring alarm of the DTCU)

The following part takes the temperature monitoring of the DTCU as an example to describe the commissioning of the temperature monitoring alarm of the monitoring board.

NOTE l Trigger conditions of Temperature Too High Alarm: When the actual temperature of DTCU exceeds the High Temperature Alarm Threshold , the DTCU reports the Temperature Too High Alarm.

l Trigger condition of Temperature Too Low Alarm: When the actual temperature of DTCU exceeds the Low Temperature Alarm Threshold , the DTCU reports the Temperature Too Low Alarm.

l On the LMT, choose Alarm Maintenance > Browse Alarm . Check the alarm information in the displayed Browse Alarm dialog box.
