The APD double-line industrial telephone set is the terminal that makes it possible to have calls over 2 independent telephone lines and can be coupled with any CB telephone exchange. It is designed for being used wherever there are difficult working conditions, e.g. very high humidity, noise, dustiness, mechanical exposures, polluted atmosphere. It is recommended for installation at industrial halls, guardrooms, construction sites, warehouses and non-methane mines etc.
High level of call signal volume and very intensive optical signaller visible from a far distance ensure efficient calling even in environments with high noise level and high dustiness degree.
The telephone casing provides dust- and splash-proofness with IP65 grade of protection.
The telephone set is designed for operation within the temperature range of -25°C to 60°C.
