EXTERNAL ALARM’S AT BTS SITE

AMIT MISHRA 2

INTRODUCTION

Alarm’s are used to monitor the site in case of any fault occur then

alarm panel automatically generate the alarm for corresponding fault occurred at site.

AMIT MISHRA 3

Why alarm’s are used at site?

External alarm is important at BTS site because in case of any fault occur then as a maintenance engineer it will be easier for us to identify the problem and rectify it accordingly. We can check at DDF, where termination of alarm is done. It provide security and stability to whole BTS site.

ALARM NAME OR SYNTAX OR TITLE

It define the name of the alarm at BTS site. It may differ according to the operator. Depending upon BTS used syntax or title can change. Some of the example of name of alarm operator are as follow’s..

PARAMETER DESCRIPTION CONTINUED

ALARM TYPE

ALARM NO

Every operator decide a particular alarm no for it’s BTS site and accordingly series of alarm is decided. for eg-7401 in NOKIA flexi BTS case.

ALARM TYPE

Type of alarm mean’s that either alarm will be normally Closed or normally open. Normally open mean’s that state of alarm in normal condition is OPEN. Normally closed mean’s that state of alarm in normal condition is closed.

MAJOR

MINOR

CRITICAL

Critical mean’s that ,it require immediate attention, if on BTS site any alarm is critical defined that mean’s that level of alarm severity is high. for eg : LLOP- low lubricant oil pressure.

MAJOR

Major mean’s that ,it’s severity level is lesser than critical but it is also needed attention as soon as possible. for eg: low fuel level

MINOR

Minor mean’s that ,it’s severity level is lesser in compare to other alarm and site may not get affected as much as in case of critical and major. for eg- site on DG.

ALARM PORT

Alarm port or pin no is decided by operator itself .

COLOUR CODE

The colour code of alarm wire is decided by operator itself. Always it will exist in pair for PCM cable’s used.

ROOT CAUSE

• IT DECIDE THE CAUSE OF ALARM

ROUTE OF ALARM

It decide the route of alarm or we can say that where alarm connection start till termination of that alarm.

ROOT CAUSE

Root cause mean’s the exact cause of fault which led to the alarm at the site.

AMIT MISHRA 11

ALARM CABLE CONNECTION Alarm cable are PCM cable. They exist in pair’s. Each alarm will be connected to ddf with these cable.(two wire is one pair) 37 pin D-type connector. Alarm ddf installed on shelter wall. Alarm’s are connected to sensor’s.

TO ELABORATE ABOVE DESCRIPTION TAKE EXAMPLE OF NOKIA FLEXI BTS

There are 12 external alarm for nokia flexi BTS. For 12 alarm connection ,we need 37 pin D connector in which 24 pin’s will be used. For each alarm , we require one pair E1 cable having two wire. Termination of these cable is done on DDF i.e from BTS to DDF and from alarm sensor to DDF.

MATERIAL REQUIREMENT- ALARM CABLE KRONE RACK CAT-5 CABLE 7-9 METER SOLDERING IRON OTHRE BASIC TOOL’S

AMIT MISHRA 42


INSTALLATION PROCESS- Initial step before installation-

(1)Alarm cable is too long so cut it into two pieces.

(2)1st cable will be used to take alarm from rectifier smart pack i/o ports to crone.

(3)2nd cable with connector at one end will be used for taking alarms from krone to BTS EAC port(2G cabinet).

AMIT MISHRA 43


INSTALLATION PROCESS CONTINUE-

STEP-1 KRONE INSTALLATION

Install the krone on rack and fix this rack in rectifier cabinet. Use proper size bolt’s and washer.

AMIT MISHRA 44

Alarm cable installation(BTS – KRONE)


Connect the alarm cable connector on EAC port at BTS(2G cabinet) Bring the other end of alarm cable to rectifier through roxtec. Punch the alarm cable on the lower side of krone according to the alarm’s sequence. The alarm cable should be fixed properly with ties and properly routed.

AMIT MISHRA 45


Route this cable properly with ties and fix it near the Rectifier I/O ports

• Connect Green & White Green (Alarm nu 1) with Pins 8 & 9 of CON1

(X1)

• Connect Grey & White Grey (Alarm nu 4) with Pins 9 & 10 of CON2

(X2)

• Connect Violet & White Violet (Alarm nu 3) with Pins 15 & 16 of

CON2 (X2)

• Connect Blue & White Blue (Alarm nu 2) with Pins 18 & 19 of CON2

AMIT MISHRA 52

Overall summary is that on any BTS site external alarm’s are important. Alarm’s make fault finding easy. External alarm’s make BTS site safer and easy to maintain. Each alarm has it’s own importance cannot be neglected.
