World Cement,

The radios are in constant use seven days a week and 24 hr/d. Since they must operate in demanding conditions – users are outside for prolonged periods – Hope Cement selected radios certified with IP57/67 ratings to ensure protection from particles and water ingress. The models include 50 DP 3400 and DP 3600 and 14 ATEX DP 4800 mobile radios.

As well as communications between users and talk groups, supervisors also wanted to call teams using their mobile phones. DCRS installed Mototrbo’s Digital Telephone Interconnect feature – a simple upgrade requiring a software revision for the radios and the connection of an analogue phone patch box to the repeaters.

Mototrbo DP3400 and ATEX certified DP4800 two-way digital radios.

The site presents some challenging conditions, including quarry and manufacturing areas, but the radios’ robust construction, high IP rating and ATEX compliance ensure continuing operation. In terms of safety, the radios support lone-worker and man-down features and have a dedicated emergency button; when pressed, a call is made to central dispatch in order for help to be sent quickly. And an override channel enables an ‘all call’ to be made (sending a message to all users at once) to instigate emergency procedures if an incident occurs.

Another key reason behind Hope Cement’s decision to install Mototrbo was the fact that it can support the phased transition from analogue to digital radios. DCRS set one of the Capacity Plus channels in analogue mode and programmed the analogue channel into the Mototrbo radios to support seamless calling between the old analogue and new digital devices. The configuration enabled Hope Cement to add new Mototrbo radios in accordance with budget limits.

Enhanced communications delivers greater safety for Hope Cement’s team.

Clear communications in challenging conditions

Hope Cement now has a high-capacity digital two-way radio system that provides clear voice communications across the entire site – against constant background noise. As well as group and individual calls, supervisors and teams can communicate seamlessly between radios and mobile phones. Engineered tough and designed to cope with challenging industrial environments and harsh weather, the Mototrbo radios ensure reliable continuous operation, while the man-down functionality and override emergency calling feature help enhance site team safety.

With a true digital system and the option to add data services in the future, Hope Cement has the reliable, high-performance and scalable two-way radio platform to support safe and effective operations well into the future.
