Button alarm

A push-button alarm is a common safety device used to issue alarm signals in emergencies. Its main working principle is to control the circuit's continuity by opening and closing the contacts of a push-button switch, thereby triggering the alarm's ringing or flashing light warning functions.
The purpose of a push-button alarm is to provide a rapid and effective alarm signal in emergencies. It is widely used in various public places, enterprises, institutions, schools, hospitals, supermarkets, shopping malls, and other locations to ensure the safety of people and property.
The operating conditions of a push-button alarm generally include the following: First, the stability of the power supply; the power supply voltage must match the device's operating voltage range. Second, the ambient temperature should not be too high or too low, typically between 0℃ and 50℃. Finally, the sensitivity of the push-button switch contacts must meet the device's requirements.
Test parameters include: the force required to trigger the button, the contact resistance of the switch contacts, current, and voltage. Before use, relevant tests and adjustments are necessary to ensure the device functions properly.
