Tips: Where to install a motor alarm?
In general, a motor alarm can cover a range of 1 square kilometer. If motor alarm is used for air raid warning, the air defense department will set the motor alarm according to this distance. However, in the process of sound transmission, it will be blocked by high-rise buildings. Generally, in dense populated areas in city, the installation of alarms is relatively dense. In open areas, the motor alarm quantity is less. In addition, the gathering places such as squares or schools are also important places to install motor alarms.
