2. Pre PAT
During pre PAT ensure the below points
• BTS layout
• Qua ty c ec o BTS RF umper VSWR E1 ca es EMU nsta at on etc.
• External Alarms verification with Emanco confirmation.

• Check if the Layout is matched with the Actual
Installation
• If found any mismatch escalate immediately

Quality check
• Check all the jumpers quality, should be as per
huawei standard
• Check E1 cable, alarm cable, power cables. All
standard, there should not be loop of any
cables. If loop is necessary put it inside the
BTS cabinet.
• EMU installation must be standardized.

• 100% accurate test – Mark the cables of one alarm pair as Front Side BATB and Back side BATB as per the existing connections
– Then Remove this alarm pair from BATB Telecom Side (Siemens)
–
Tune
multimeter to
DC
Voltage – Connect Red pole from multimeter to the cable marked as Front side BATB
– Connect Black pole from multimeter to the cable marked as Back side BATB
– If the value is Positive then cable marked as Front side BATB is Positive and the cable marked as Back side BATB is negative
– If the value is negative then cable marked as Front side BATB is negative and the Back side BATB is positive
–
• 99 % sites which is having BATA civil end Black is Negative (Common) and White is Positive, check figure‐1
• In some cases the Ne ative common is loo with each other exam le check fi ure‐2
• In sites not having BATB do same testing on the Siemens Krone, Disconnect one alarm, mark the cables and test by above procedure.

How to check Normally Open and Normally Closed
• 100% Accurate Testing:
–
– Disconnect alarms from Telecom side (Siemens)
– Tune multimeter on
Buzzer
– Check i there is buzzer on the civil side
– If there is buzzer means normally closed
– If there is no buzzer means normally open
–
The
Alarms
currently
coming
(Active)
will
have
opposite
status,
• For example if AC‐1 alarm is coming
• Check if buzzer is received on all other alarms and no buzzer on AC‐1 alarm
• s means a a a arms are norma y c ose
• And if there is buzzer on AC‐1 alarm and other alarms no buzzer.
• This means that all alarms normally open.

• Polarization from BATB civil End – Black is negative
• From Telecom End the solid color is +ive, Dashed (white with color) is –ive.
• In Siemens Rectifier Black is +ive, Blue is –ive(for alarms directly connected)
• Connectivity for
Siemens
Rectifier:
– 149: Battery Discharge
– 147: Power Major
– 146+148 series connection: Power Minor
– Commercial Power will be connected to BATB as usual.
