KNTECH KNEx8 is the VoIP version of the KNEx explosion-proof telephone with loudspeaker. It is ATEX marked II 2G Ex db ib IIB T5 Gb and registers on a SIP 2.0 IP-PBX over the plant LAN.
A built-in amplifier drives an external 8 ohm 30 W explosion-proof horn, so the KNEx8 can be used as a telephone and local paging point in the same housing. KNTECH also uses the KNEx8 as a field station in its PAGA systems.
