LARGE POWER ALARM SIGNAL - PLATE

Producer: AVT

An inseparable element of every reliable alarm system. The siren was designed in the most simplified way, from generally available elements. The signal is generated in two symmetrical multivibrators that cooperate with each other. One of them provides a signal modulating the work of the other. As a result, the acoustic signal builds up and falls, which makes it well recognizable.
The signal from the multivibrators is directed to the power amplifier supplemented with capacitors filtering / disarming the power supply.

The device is especially recommended in alarm systems, all those who need a reliable sounder
