The DP4401Ex is a digital two-way radio built to ATEX specifications, with 32 channels that allow communication within a team and the ability to make individual and group calls, depending on whether a private or group conversation is needed.
It is certified for safe use in hazardous working environments and can be used in potentially explosive atmospheres such as the natural-gas, oil and mining industries.
The IP67 ingress protection means the radio is fully protected against dust ingress, and is also protected against submersion in water for long periods.
With a rugged design, the DP4401Ex is built to military standards (MIL-STD-810 C / D / E / F / G), covering a wide range of environmental conditions; the radio keeps working from -30°C to 60°C.
As the DP4401Ex is designed for use in hazardous working environments, it has many features to help keep workers safe, alongside GPS that lets operators be tracked at their exact locations — which helps improve efficiency as well as safety.
The DP4401Ex uses a transmit-interrupt function so a user can get an important message through to any ongoing conversations. This can be used when an incident has occurred or when new instructions need to reach a group of workers. The Lone Worker and Man Down features identify whether an operator is in danger.
Lone Worker monitors the DP4401Ex's activity levels; if it is inactive for a preset period, the radio sounds an audible alert, and if there is still no response, a notification is sent to a base station or to other radios on the network to make them aware of the situation. Man Down works similarly, but instead of monitoring activity levels it monitors the radio's orientation, watching its position over an extended period.
It comes with the standard 2075 mAh Li-Ion battery, giving up to 19 hours of operation in digital mode and 16 hours in analogue mode. (test based on a 5/5/90 duty cycle)
Many additional accessories are available for use with the DP4801Ex, ATEX-certified to ensure safe use within users' working environment and compatible with the radio.
