Its  the factory security system that is going off. I took a look at the door pins and hood/trunk pins to ensure they are not broken/loose.But everything looks all right. Sometimes it goes off once a day and sometimes at 2-3 days interval. I took out the fuse with anti theft written but it still foes off.Right now I took the connection to the horn off so that it doesnot disturb my peaceful neighbour. But I want to solve this problem permanently by completely making this system off.I need your help.My mechanic is also out of town. please help me

Going on the assumption this is an after market alarm system, I would have to say that you missed a fuse.  Most alarm systems have more than one, typically one that protects the parking light output (also preventing bypassing by shorting the bulb) and at least one for the brain of the alarm itself.  I would say to trace back the wire from where you removed the fuse and disconnect all of the harnesses that are connected to the brain of the system.  

If I am wrong with my assumption of it being an after market alarm and it is the factory security system that is going off I would take a look at the door pins and hood/trunk pins to ensure they are not broken/loose.

If you tell me the make model and year of the car, it may have a factory disarm wire that you can ground permanently to prevent the alarm from arming in the first place.

Answer
DEI lists:

Factory Alarm Disarm    lt.grn/blk/ sil dots      -     anti-theft module

Grounding this wire should disable your factory alarm.  

I am not completely familiar with the Nissan factory security system, you may be able to just unplug the harnesses from the security module and disable it all together.  I would suggest posting this question to http://www.nissanforum.com/ someone there may be able to better answer if pulling the security module would effect anything else.
