  • external control signal;
  • automatically - by timer.

The notification mode is set using a group of microswitches.

The sirens are produced with supply voltage:

  • 12-27V DC;
  • 220V AC.

Distinctive features:

  • Fully sealed housing with IP67 degree of protection;
  • two-stage notification with automatic or external control;
  • a wide choice of different types of sound notification independently for each step;
  • independent programming by the user of the operating mode;
