ESIS is delighted to announce that Guardian Telecom has recently appointed ESIS as their Sales Representative for Europe for their wide range of Hazardous areas and Ruggedized telephones.

We are not representing the PAGA or Intercom Systems which Guardian currently has or develops in the future.

Guardian telephones are engineered from the ground up to work reliably and last – especially in the roughest weather, toughest applications, and most extreme environments. Each product is fully integrated “Ruggedized” high-performance telecommunications equipment for non-hazardous, hazardous, Class I Division 1, Class I Division 2 and other hardened equipment applications needed around the globe.

Guardian is certified under ISO 9001:2008; CSA Type 4X, UL, ATEX; NEC: Class I & II Division 1 & 2, IEC: Zone 1; and NEMA IP66.
