Motorola DGP8550Ex Two Way Radio
Motorola DGP8550Ex
The Motorola DGP8550EX is a high-end explosion-proof walkie-talkie that combines robust and reliable two-way communication with the highest levels of ATEX and IECEx protection. Its striking blue casing serves as a visual identifier, ensuring that only ATEX-certified equipment can enter hazardous areas. It meets the stringent emergency communication requirements of the oil, gas, chemical, and mining industries.
Main features
Highest Level ATEX and IECEx Safety Certifications
The DGP8550Ex has been certified to the highest international standards for safe use in explosive environments. It is ATEX and IECEx certified for gas environments (II 2G Ex ib IIC T4 Gb), dust environments (II 2D Ex ib IIIC T130°C Db), and mining environments (IM2 Ex ib I Mb). This comprehensive certification ensures safe use even in the most hazardous environments.
IP67 Protection Rating and Military Standards
This Motorola ATEX radio is designed for the most demanding environments, meeting or exceeding MIL-STD-810 standards, offering superior resistance to shock, vibration, and extreme temperatures. It boasts an IP67 protection rating, meaning it is completely dustproof and can be submerged in 1 meter of water for up to 30 minutes.
Superior Digital Audio in Extreme Noise Environments
Clear communication in high-noise environments is crucial for safety. The DGP8550Ex utilizes MOTOTRBO digital technology to deliver loud, clear, and easy-to-understand audio. Innovative features such as Intelligent Audio automatically adjust volume based on ambient noise levels, ensuring information penetrates the roar of heavy machinery, engines, and alarms.
Designed for Gloves and High-Intensity Operations
In a race against time, ease of use is paramount. The DGP8550Ex features large, comfortable-touch PTT, volume, and channel knobs, making it easy to operate even with thick gloves. A prominent orange emergency button allows for quick and easy access for workers to call for assistance. A large color display and bright LED indicators provide clear visibility of critical status information.
Personnel Fall Alarm and Lone Work Alarm
In addition to physical protection, this radio integrates intelligent safety software. Built-in personnel fall alarm and lonely work alarm functions automatically trigger emergency alarms when a worker becomes incapacitated or fails to respond to periodic prompts. This instant notification can determine the success or failure of a rescue operation and prevent tragedy.
Leveraging MOTOTRBO networks to extend coverage and capacity
The DGP8550Ex is not isolated. It supports advanced MOTOTRBO systems such as IP Site Connect (extending global coverage using the internet) and Capacity Plus (increasing user capacity at a single site to over 1000 people). Linked Capacity Plus combines the two for wide-area, high-density connectivity.
