What Is A Hand Operated Siren

A Hand operated siren is a type of siren that has a distinct handle at the back of the main head. When you rotate that handle it produces a sound which as a warning sign for people working there that a fire emergency has occurred at your place everyone gets to a safe place. What makes hand operated sirens different from other types of electric and automatic sirens is that it can be used at the time of no electricity when all the automatic and electronic equipment fail to respond even at that time you can warn everyone about the fire emergency and save them from any casualty.

How Does Hand Operated Siren Works
As from the name it depicts that its hand operated so there is no need for any kind of electric input since it would be working with your energy and intensity by which you will be rotating the handle a few times to produce a sound slowly getting louder with every turn you make. It has a motor installed inside that drives the shaft which is attached to a rotor, also called a chopper or fan, to both the ends. Every rotor is surrounded by a stator, a sort of casing, which has a various number of holes that are rectangular in shape.
Each of the blades of the hand operated siren draws and forces the air out through the slots inside the stator while the plates at the end of each of the blades stop or interrupt the flow. As a result, it creates rarefied and alternating compressed air pressure that produces a deafening sound.
In easy works the rotation of the handle generates electricity which powers the sound of the siren, the reach and intensity of the siren increase with the increase of speed of rotation.
