WIRELESS METHANE GAS DETECTION AND PROTECTION SYSTEM
Prefer AirMesh contains wireless methane gas detector and ELEKTROGAS normal-open solenoid valve with manual reset that operates at 12V voltage.
SECURE - 128/256 bit AES Banking encryption Standard
DIGITALLY CALIBRATED - individual alarm threshold setting at preset gas concentrations
CONFIGURABLE - via Primatech AirMesh Config App
REDUNDANT PROTECTION - Mesh Technology - NSPOF No Single point of failure
FLEXIBLE - the components of the network can be relocated
NO WIRES, NO HOLES IN THE WALLS - detectors are applied directly to the wall and communicate wirelessly
SCALABLE - the system can be expanded with components from the AirMesh range
SAFE RADIO EMISSIONS - system according to RED 2014/53/EU directive
