The siren/loudspeaker GS-2 is designed to play recorded verbal warning messages upon alarms in the two-threshold gas detection systems made by GAZEX.

The siren can be used in large enclosed spaces allowing the transmission of clear messages to those who should be warned of alarms in the system of gas detection.

GS-2 cannot be used in areas designated as “zone of danger of explosion”.

  • SD memory slot for programming spoken messages (only GS-2) - choice of about 30 versions of the message (using the optional software.);
  • optional – the ability to configure the control inputs (number of messages) and create your own user messages (configuration software for editing and warning signals and messages);
  • High durability and reliability;
  • Easy assembly (base: 2 point mounting, the speaker: snap to base).
