Shopping malls are the luxurious and leisure way to get out of the busy and hectic life. But recently, we have witnessed a number of fire accident cases in commercial complexes, worldwide, that lead to a tragic loss of human life. The only defensive measure that can be taken to prevent it from occurring is installing a fire alarm system.
