Principle

The principle of traditional manual alarm is the application of shock sensors,auto alarm sensors work once accept vibration signal .As a result , thunders and rains,or touches of dogs and cats , even car alarms of other cars nearby,can cause alarm reaction .

The principle of manual  alarm is turning the crank ,the gear box of 

progressive transmission ,through the transmission block driving wheel at high speed .In the process of high speed , high speed and high pressure to set the wheel on absorption of air fixed window of resonance in extrusion and at the same time, to play the role of alarm.

Becasue it is manual alarm , the primary speed determines the sound effect of the alarm. The speed and the sound effect is proportinal , relatively speaking , the higher the speed , the greater the sound . There are some differences from man to man to shake the alarm. The height , 

strength ,shaking speed of the man who shake the alarm influences the alarm sound effect. So we are here for macro regulation ,the primary speed of shaking should not less than 90r/min, otherwise it will not sound effect.

  

Operation & Maintenance 

 

1 The operation of manual alarm need one man only . While alarms at work , the wheel inside is working at high speed ,generally more than 

2000r/min , Don't put your fingers or other foreign body into  the wheel inside, otherwise it will cause personal injury or cause damage to the alarm.

2 Juveniles are not alllowed to use manual alarms.

3 the alarm require regular maintenance to keep normal operation.If alarm fails to operate properly , arrange for an experienced mechanics or directly contact the company .
