Technical details

HTT is the most advanced signaling device offered by Atest Gaz. The device has an acoustic and optical module and is also designed to work in the explosion hazard zone (Ex). The device allows personalized configuration tailored to the needs of demanding customers and with consideration to specific features of target markets.

 

  • The signalling device is equipped with LED modules that allow for any configuration using 5 colours and the two-threshold acoustic signaling function, so you can easily identify the state of emergency in the facility By default, these values ​​are 110 dB for an alarm and 70 dB for an alarm confirmed by the service.
  • The device body made of stainless steel and IP65 protection index enable operation of the HTT under the most demanding and harsh environmental conditions, with presence of aggressive factors, dust or liquids.
  • HTT guarantees reliability thanks to the use of a solution based on LED diodes and a Flash module – built with High Power LED diodes. The applied solution facilitates the identification of the threat state thanks to the generated flashes causing light reflections on the elements of the technological installation.

 

The use of the presented solution allows to standardize the communication system in the facility, thanks to which all employees can quickly and unambiguously determine the current level of risk at the workplace.
