MINIATURE ALARM SIGNALING - SET ASSEMBLED AND STARTED

Producer: AVT

A simple but effective generator of alarm signals. Built on the UM3561 integrated circuit. The generated sounds are stored in the built-in ROM of organization of 256 8-bit words. The choice of the type of signal generated is possible thanks to the two-input selector. There is a very simple single-transistor acoustic signal amplifier on the board. Thanks to this, the sound can be emitted by a small loudspeaker.
A properly assembled system does not require any commissioning activities.

The device is especially recommended for people who want to achieve eye-catching alarm signals for modelers
