According to Dallas City, it is announced that an alarm that sounded at 156 locations in the city in the early midnight is not a notification of an emergency situation but a crime by someone outside. I am trying to figure out the criminal as "looking for a single needle from the hay of the hay", but the city of Dallas is in the process of investigating the vulnerability of the cause and alarm system.


Emergency alarm began to sound at around 0:30 on Saturday, April 8, 2017 local time, fire fighters and others took care of the problem, but the alarm kept ringing for about an hour is. As suddenly the alarm began to sound everywhere, there were 4,400 911 notifications arriving during the time between the incident and 3 AM. This is more than twice the average number of 911 reports usually from 23 o'clock to 7 o'clock the next time, it can be seen that the city was panicked. Dallas city called on 'Twitter' because alarm is a malfunction of the system on Twitter ', 911 line seems to be waiting for 6 minutes around 0:15.

Please empty. Please do NOT call 911. Thank you.
